-
-Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
-Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
-
-In addition to negotiator, it allows:
-
-- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
-  as well as `('text/html', 'application/json')`.
-- Allows type shorthands such as `json`.
-- Returns `false` when no types match
-- Treats non-existent headers as `*`

-## Installation
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install accepts
-```
-
-## API
-
-```js
-var accepts = require('accepts')
-```
-
-### accepts(req)
-
-Create a new `Accepts` object for the given `req`.
-
-#### .charset(charsets)
-
-Return the first accepted charset. If nothing in `charsets` is accepted,
-then `false` is returned.
-
-#### .charsets()
-
-Return the charsets that the request accepts, in the order of the client's
-preference (most preferred first).
-
-#### .encoding(encodings)
-
-Return the first accepted encoding. If nothing in `encodings` is accepted,
-then `false` is returned.
-
-#### .encodings()
-
-Return the encodings that the request accepts, in the order of the client's
-preference (most preferred first).
-
-#### .language(languages)
-
-Return the first accepted language. If nothing in `languages` is accepted,
-then `false` is returned.
-
-#### .languages()
-
-Return the languages that the request accepts, in the order of the client's
-preference (most preferred first).
-
-#### .type(types)
-
-Return the first accepted type (and it is returned as the same text as what
-appears in the `types` array). If nothing in `types` is accepted, then `false`
-is returned.
-
-The `types` array can contain full MIME types or file extensions. Any value
-that is not a full MIME type is passed to `require('mime-types').lookup`.
-
-#### .types()
-
-Return the types that the request accepts, in the order of the client's
-preference (most preferred first).
-
-## Examples
-
-### Simple type negotiation
-
-This simple example shows how to use `accepts` to return a different typed
-respond body based on what the client wants to accept. The server lists it's
-preferences in order and will get back the best match between the client and
-server.
-
-```js
-var accepts = require('accepts')
-var http = require('http')
-
-function app (req, res) {
-  var accept = accepts(req)
-
-  // the order of this list is significant; should be server preferred order
-  switch (accept.type(['json', 'html'])) {
-    case 'json':
-      res.setHeader('Content-Type', 'application/json')
-      res.write('{"hello":"world!"}')
-      break
-    case 'html':
-      res.setHeader('Content-Type', 'text/html')
-      res.write('<b>hello, world!</b>')
-      break
-    default:
-      // the fallback is text/plain, so no need to specify it above
-      res.setHeader('Content-Type', 'text/plain')
-      res.write('hello, world!')
-      break
-  }
-
-  res.end()
-}
-
-http.createServer(app).listen(3000)
-```
-
-You can test this out with the cURL program:
-```sh
-curl -I -H'Accept: text/html' http://localhost:3000/
-```

-Node.js body parsing middleware.
-
-Parse incoming request bodies in a middleware before your handlers, available
-under the `req.body` property.
-
-**Note** As `req.body`'s shape is based on user-controlled input, all
-properties and values in this object are untrusted and should be validated
-before trusting. For example, `req.body.foo.toString()` may fail in multiple
-ways, for example the `foo` property may not be there or may not be a string,
-and `toString` may not be a function and instead a string or other user input.
-
-[Learn about the anatomy of an HTTP transaction in Node.js](https://nodejs.org/en/docs/guides/anatomy-of-an-http-transaction/).
-
-_This does not handle multipart bodies_, due to their complex and typically
-large nature. For multipart bodies, you may be interested in the following
-modules:
-
-  * [busboy](https://www.npmjs.org/package/busboy#readme) and
-    [connect-busboy](https://www.npmjs.org/package/connect-busboy#readme)
-  * [multiparty](https://www.npmjs.org/package/multiparty#readme) and
-    [connect-multiparty](https://www.npmjs.org/package/connect-multiparty#readme)
-  * [formidable](https://www.npmjs.org/package/formidable#readme)
-  * [multer](https://www.npmjs.org/package/multer#readme)
-
-This module provides the following parsers:
-
-  * [JSON body parser](#bodyparserjsonoptions)
-  * [Raw body parser](#bodyparserrawoptions)
-  * [Text body parser](#bodyparsertextoptions)
-  * [URL-encoded form body parser](#bodyparserurlencodedoptions)
-
-Other body parsers you might be interested in:
-
-- [body](https://www.npmjs.org/package/body#readme)
-- [co-body](https://www.npmjs.org/package/co-body#readme)
-
-## Installation
-
-```sh
-$ npm install body-parser
-```
-
-## API
-
-```js
-const bodyParser = require('body-parser')
-```
-
-The `bodyParser` object exposes various factories to create middlewares. All
-middlewares will populate the `req.body` property with the parsed body when
-the `Content-Type` request header matches the `type` option.
-
-The various errors returned by this module are described in the
-[errors section](#errors).
-
-### bodyParser.json([options])
-
-Returns middleware that only parses `json` and only looks at requests where
-the `Content-Type` header matches the `type` option. This parser accepts any
-Unicode encoding of the body and supports automatic inflation of `gzip`,
-`br` (brotli) and `deflate` encodings.
-
-A new `body` object containing the parsed data is populated on the `request`
-object after the middleware (i.e. `req.body`).
-
-#### Options
-
-The `json` function takes an optional `options` object that may contain any of
-the following keys:
-
-##### defaultCharset
-
-Specify the default character set for the json content if the charset is not
-specified in the `Content-Type` header of the request. Defaults to `utf-8`.
-
-##### inflate
-
-When set to `true`, then deflated (compressed) bodies will be inflated; when
-`false`, deflated bodies are rejected. Defaults to `true`.
-
-##### limit
-
-Controls the maximum request body size. If this is a number, then the value
-specifies the number of bytes; if it is a string, the value is passed to the
-[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
-to `'100kb'`.
-
-##### reviver
-
-The `reviver` option is passed directly to `JSON.parse` as the second
-argument. You can find more information on this argument
-[in the MDN documentation about JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Example.3A_Using_the_reviver_parameter).
-
-##### strict
-
-When set to `true`, will only accept arrays and objects; when `false` will
-accept anything `JSON.parse` accepts. Defaults to `true`.
-
-##### type
-
-The `type` option is used to determine what media type the middleware will
-parse. This option can be a string, array of strings, or a function. If not a
-function, `type` option is passed directly to the
-[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
-be an extension name (like `json`), a mime type (like `application/json`), or
-a mime type with a wildcard (like `*/*` or `*/json`). If a function, the `type`
-option is called as `fn(req)` and the request is parsed if it returns a truthy
-value. Defaults to `application/json`.
-
-##### verify
-
-The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
-where `buf` is a `Buffer` of the raw request body and `encoding` is the
-encoding of the request. The parsing can be aborted by throwing an error.
-
-### bodyParser.raw([options])
-
-Returns middleware that parses all bodies as a `Buffer` and only looks at
-requests where the `Content-Type` header matches the `type` option. This
-parser supports automatic inflation of `gzip`, `br` (brotli) and `deflate`
-encodings.
-
-A new `body` object containing the parsed data is populated on the `request`
-object after the middleware (i.e. `req.body`). This will be a `Buffer` object
-of the body.
-
-#### Options
-
-The `raw` function takes an optional `options` object that may contain any of
-the following keys:
-
-##### inflate
-
-When set to `true`, then deflated (compressed) bodies will be inflated; when
-`false`, deflated bodies are rejected. Defaults to `true`.
-
-##### limit
-
-Controls the maximum request body size. If this is a number, then the value
-specifies the number of bytes; if it is a string, the value is passed to the
-[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
-to `'100kb'`.
-
-##### type
-
-The `type` option is used to determine what media type the middleware will
-parse. This option can be a string, array of strings, or a function.
-If not a function, `type` option is passed directly to the
-[type-is](https://www.npmjs.org/package/type-is#readme) library and this
-can be an extension name (like `bin`), a mime type (like
-`application/octet-stream`), or a mime type with a wildcard (like `*/*` or
-`application/*`). If a function, the `type` option is called as `fn(req)`
-and the request is parsed if it returns a truthy value. Defaults to
-`application/octet-stream`.
-
-##### verify
-
-The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
-where `buf` is a `Buffer` of the raw request body and `encoding` is the
-encoding of the request. The parsing can be aborted by throwing an error.
-
-### bodyParser.text([options])
-
-Returns middleware that parses all bodies as a string and only looks at
-requests where the `Content-Type` header matches the `type` option. This
-parser supports automatic inflation of `gzip`, `br` (brotli) and `deflate`
-encodings.
-
-A new `body` string containing the parsed data is populated on the `request`
-object after the middleware (i.e. `req.body`). This will be a string of the
-body.
-
-#### Options
-
-The `text` function takes an optional `options` object that may contain any of
-the following keys:
-
-##### defaultCharset
-
-Specify the default character set for the text content if the charset is not
-specified in the `Content-Type` header of the request. Defaults to `utf-8`.
-
-##### inflate
-
-When set to `true`, then deflated (compressed) bodies will be inflated; when
-`false`, deflated bodies are rejected. Defaults to `true`.
-
-##### limit
-
-Controls the maximum request body size. If this is a number, then the value
-specifies the number of bytes; if it is a string, the value is passed to the
-[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
-to `'100kb'`.
-
-##### type
-
-The `type` option is used to determine what media type the middleware will
-parse. This option can be a string, array of strings, or a function. If not
-a function, `type` option is passed directly to the
-[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
-be an extension name (like `txt`), a mime type (like `text/plain`), or a mime
-type with a wildcard (like `*/*` or `text/*`). If a function, the `type`
-option is called as `fn(req)` and the request is parsed if it returns a
-truthy value. Defaults to `text/plain`.
-
-##### verify
-
-The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
-where `buf` is a `Buffer` of the raw request body and `encoding` is the
-encoding of the request. The parsing can be aborted by throwing an error.
-
-### bodyParser.urlencoded([options])
-
-Returns middleware that only parses `urlencoded` bodies and only looks at
-requests where the `Content-Type` header matches the `type` option. This
-parser accepts only UTF-8 encoding of the body and supports automatic
-inflation of `gzip`, `br` (brotli) and `deflate` encodings.
-
-A new `body` object containing the parsed data is populated on the `request`
-object after the middleware (i.e. `req.body`). This object will contain
-key-value pairs, where the value can be a string or array (when `extended` is
-`false`), or any type (when `extended` is `true`).
-
-#### Options
-
-The `urlencoded` function takes an optional `options` object that may contain
-any of the following keys:
-
-##### extended
-
-The "extended" syntax allows for rich objects and arrays to be encoded into the
-URL-encoded format, allowing for a JSON-like experience with URL-encoded. For
-more information, please [see the qs
-library](https://www.npmjs.org/package/qs#readme).
-
-Defaults to `false`.
-
-##### inflate
-
-When set to `true`, then deflated (compressed) bodies will be inflated; when
-`false`, deflated bodies are rejected. Defaults to `true`.
-
-##### limit
-
-Controls the maximum request body size. If this is a number, then the value
-specifies the number of bytes; if it is a string, the value is passed to the
-[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
-to `'100kb'`.
-
-##### parameterLimit
-
-The `parameterLimit` option controls the maximum number of parameters that
-are allowed in the URL-encoded data. If a request contains more parameters
-than this value, a 413 will be returned to the client. Defaults to `1000`.
-
-##### type
-
-The `type` option is used to determine what media type the middleware will
-parse. This option can be a string, array of strings, or a function. If not
-a function, `type` option is passed directly to the
-[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
-be an extension name (like `urlencoded`), a mime type (like
-`application/x-www-form-urlencoded`), or a mime type with a wildcard (like
-`*/x-www-form-urlencoded`). If a function, the `type` option is called as
-`fn(req)` and the request is parsed if it returns a truthy value. Defaults
-to `application/x-www-form-urlencoded`.
-
-##### verify
-
-The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
-where `buf` is a `Buffer` of the raw request body and `encoding` is the
-encoding of the request. The parsing can be aborted by throwing an error.
-
-##### defaultCharset
-
-The default charset to parse as, if not specified in content-type. Must be
-either `utf-8` or `iso-8859-1`. Defaults to `utf-8`.
-
-##### charsetSentinel
-
-Whether to let the value of the `utf8` parameter take precedence as the charset
-selector. It requires the form to contain a parameter named `utf8` with a value
-of `✓`. Defaults to `false`.
-
-##### interpretNumericEntities
-
-Whether to decode numeric entities such as `&#9786;` when parsing an iso-8859-1
-form. Defaults to `false`.
-
-
-##### depth
-
-The `depth` option is used to configure the maximum depth of the `qs` library when `extended` is `true`. This allows you to limit the amount of keys that are parsed and can be useful to prevent certain types of abuse. Defaults to `32`. It is recommended to keep this value as low as possible.
-
-## Errors
-
-The middlewares provided by this module create errors using the
-[`http-errors` module](https://www.npmjs.com/package/http-errors). The errors
-will typically have a `status`/`statusCode` property that contains the suggested
-HTTP response code, an `expose` property to determine if the `message` property
-should be displayed to the client, a `type` property to determine the type of
-error without matching against the `message`, and a `body` property containing
-the read body, if available.
-
-The following are the common errors created, though any error can come through
-for various reasons.
-
-### content encoding unsupported
-
-This error will occur when the request had a `Content-Encoding` header that
-contained an encoding but the "inflation" option was set to `false`. The
-`status` property is set to `415`, the `type` property is set to
-`'encoding.unsupported'`, and the `charset` property will be set to the
-encoding that is unsupported.
-
-### entity parse failed
-
-This error will occur when the request contained an entity that could not be
-parsed by the middleware. The `status` property is set to `400`, the `type`
-property is set to `'entity.parse.failed'`, and the `body` property is set to
-the entity value that failed parsing.
-
-### entity verify failed
-
-This error will occur when the request contained an entity that could not be
-failed verification by the defined `verify` option. The `status` property is
-set to `403`, the `type` property is set to `'entity.verify.failed'`, and the
-`body` property is set to the entity value that failed verification.
-
-### request aborted
-
-This error will occur when the request is aborted by the client before reading
-the body has finished. The `received` property will be set to the number of
-bytes received before the request was aborted and the `expected` property is
-set to the number of expected bytes. The `status` property is set to `400`
-and `type` property is set to `'request.aborted'`.
-
-### request entity too large
-
-This error will occur when the request body's size is larger than the "limit"
-option. The `limit` property will be set to the byte limit and the `length`
-property will be set to the request body's length. The `status` property is
-set to `413` and the `type` property is set to `'entity.too.large'`.
-
-### request size did not match content length
-
-This error will occur when the request's length did not match the length from
-the `Content-Length` header. This typically occurs when the request is malformed,
-typically when the `Content-Length` header was calculated based on characters
-instead of bytes. The `status` property is set to `400` and the `type` property
-is set to `'request.size.invalid'`.
-
-### stream encoding should not be set
-
-This error will occur when something called the `req.setEncoding` method prior
-to this middleware. This module operates directly on bytes only and you cannot
-call `req.setEncoding` when using this module. The `status` property is set to
-`500` and the `type` property is set to `'stream.encoding.set'`.
-
-### stream is not readable
-
-This error will occur when the request is no longer readable when this middleware
-attempts to read it. This typically means something other than a middleware from
-this module read the request body already and the middleware was also configured to
-read the same request. The `status` property is set to `500` and the `type`
-property is set to `'stream.not.readable'`.
-
-### too many parameters
-
-This error will occur when the content of the request exceeds the configured
-`parameterLimit` for the `urlencoded` parser. The `status` property is set to
-`413` and the `type` property is set to `'parameters.too.many'`.
-
-### unsupported charset "BOGUS"
-
-This error will occur when the request had a charset parameter in the
-`Content-Type` header, but the `iconv-lite` module does not support it OR the
-parser does not support it. The charset is contained in the message as well
-as in the `charset` property. The `status` property is set to `415`, the
-`type` property is set to `'charset.unsupported'`, and the `charset` property
-is set to the charset that is unsupported.
-
-### unsupported content encoding "bogus"
-
-This error will occur when the request had a `Content-Encoding` header that
-contained an unsupported encoding. The encoding is contained in the message
-as well as in the `encoding` property. The `status` property is set to `415`,
-the `type` property is set to `'encoding.unsupported'`, and the `encoding`
-property is set to the encoding that is unsupported.
-
-### The input exceeded the depth
-
-This error occurs when using `bodyParser.urlencoded` with the `extended` property set to `true` and the input exceeds the configured `depth` option. The `status` property is set to `400`. It is recommended to review the `depth` option and evaluate if it requires a higher value. When the `depth` option is set to `32` (default value), the error will not be thrown.
-
-## Examples
-
-### Express/Connect top-level generic
-
-This example demonstrates adding a generic JSON and URL-encoded parser as a
-top-level middleware, which will parse the bodies of all incoming requests.
-This is the simplest setup.
-
-```js
-const express = require('express')
-const bodyParser = require('body-parser')
-
-const app = express()
-
-// parse application/x-www-form-urlencoded
-app.use(bodyParser.urlencoded())
-
-// parse application/json
-app.use(bodyParser.json())
-
-app.use(function (req, res) {
-  res.setHeader('Content-Type', 'text/plain')
-  res.write('you posted:\n')
-  res.end(String(JSON.stringify(req.body, null, 2)))
-})
-```
-
-### Express route-specific
-
-This example demonstrates adding body parsers specifically to the routes that
-need them. In general, this is the most recommended way to use body-parser with
-Express.
-
-```js
-const express = require('express')
-const bodyParser = require('body-parser')
-
-const app = express()
-
-// create application/json parser
-const jsonParser = bodyParser.json()
-
-// create application/x-www-form-urlencoded parser
-const urlencodedParser = bodyParser.urlencoded()
-
-// POST /login gets urlencoded bodies
-app.post('/login', urlencodedParser, function (req, res) {
-  if (!req.body || !req.body.username) res.sendStatus(400)
-  res.send('welcome, ' + req.body.username)
-})
-
-// POST /api/users gets JSON bodies
-app.post('/api/users', jsonParser, function (req, res) {
-  if (!req.body) res.sendStatus(400)
-  // create user in req.body
-})
-```
-
-### Change accepted type for parsers
-
-All the parsers accept a `type` option which allows you to change the
-`Content-Type` that the middleware will parse.
-
-```js
-const express = require('express')
-const bodyParser = require('body-parser')
-
-const app = express()
-
-// parse various different custom JSON types as JSON
-app.use(bodyParser.json({ type: 'application/*+json' }))
-
-// parse some custom thing into a Buffer
-app.use(bodyParser.raw({ type: 'application/vnd.custom-type' }))
-
-// parse an HTML body into a string
-app.use(bodyParser.text({ type: 'text/html' }))
-```

-# Bytes utility
-
-[![NPM Version][npm-image]][npm-url]
-[![NPM Downloads][downloads-image]][downloads-url]
-[![Build Status][ci-image]][ci-url]
-[![Test Coverage][coveralls-image]][coveralls-url]
-
-Utility to parse a string bytes (ex: `1TB`) to bytes (`1099511627776`) and vice-versa.
-
-## Installation
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```bash
-$ npm install bytes
-```
-
-## Usage
-
-```js
-var bytes = require('bytes');
-```
-
-#### bytes(number｜string value, [options]): number｜string｜null
-
-Default export function. Delegates to either `bytes.format` or `bytes.parse` based on the type of `value`.
-
-**Arguments**
-
-| Name    | Type     | Description        |
-|---------|----------|--------------------|
-| value   | `number`｜`string` | Number value to format or string value to parse |
-| options | `Object` | Conversion options for `format` |
-
-**Returns**
-
-| Name    | Type             | Description                                     |
-|---------|------------------|-------------------------------------------------|
-| results | `string`｜`number`｜`null` | Return null upon error. Numeric value in bytes, or string value otherwise. |
-
-**Example**
-
-```js
-bytes(1024);
-// output: '1KB'
-
-bytes('1KB');
-// output: 1024
-```
-
-#### bytes.format(number value, [options]): string｜null
-
-Format the given value in bytes into a string. If the value is negative, it is kept as such. If it is a float, it is
- rounded.
-
-**Arguments**
-
-| Name    | Type     | Description        |
-|---------|----------|--------------------|
-| value   | `number` | Value in bytes     |
-| options | `Object` | Conversion options |
-
-**Options**
-
-| Property          | Type   | Description                                                                             |
-|-------------------|--------|-----------------------------------------------------------------------------------------|
-| decimalPlaces | `number`｜`null` | Maximum number of decimal places to include in output. Default value to `2`. |
-| fixedDecimals | `boolean`｜`null` | Whether to always display the maximum number of decimal places. Default value to `false` |
-| thousandsSeparator | `string`｜`null` | Example of values: `' '`, `','` and `'.'`... Default value to `''`. |
-| unit | `string`｜`null` | The unit in which the result will be returned (B/KB/MB/GB/TB). Default value to `''` (which means auto detect). |
-| unitSeparator | `string`｜`null` | Separator to use between number and unit. Default value to `''`. |
-
-**Returns**
-
-| Name    | Type             | Description                                     |
-|---------|------------------|-------------------------------------------------|
-| results | `string`｜`null` | Return null upon error. String value otherwise. |
-
-**Example**
-
-```js
-bytes.format(1024);
-// output: '1KB'
-
-bytes.format(1000);
-// output: '1000B'
-
-bytes.format(1000, {thousandsSeparator: ' '});
-// output: '1 000B'
-
-bytes.format(1024 * 1.7, {decimalPlaces: 0});
-// output: '2KB'
-
-bytes.format(1024, {unitSeparator: ' '});
-// output: '1 KB'
-```
-
-#### bytes.parse(string｜number value): number｜null
-
-Parse the string value into an integer in bytes. If no unit is given, or `value`
-is a number, it is assumed the value is in bytes.
-
-Supported units and abbreviations are as follows and are case-insensitive:
-
-  * `b` for bytes
-  * `kb` for kilobytes
-  * `mb` for megabytes
-  * `gb` for gigabytes
-  * `tb` for terabytes
-  * `pb` for petabytes
-
-The units are in powers of two, not ten. This means 1kb = 1024b according to this parser.
-
-**Arguments**
-
-| Name          | Type   | Description        |
-|---------------|--------|--------------------|
-| value   | `string`｜`number` | String to parse, or number in bytes.   |
-
-**Returns**
-
-| Name    | Type        | Description             |
-|---------|-------------|-------------------------|
-| results | `number`｜`null` | Return null upon error. Value in bytes otherwise. |
-
-**Example**
-
-```js
-bytes.parse('1KB');
-// output: 1024
-
-bytes.parse('1024');
-// output: 1024
-
-bytes.parse(1024);
-// output: 1024
-```

-Helper functions around Function call/apply/bind, for use in `call-bind`.
-
-The only packages that should likely ever use this package directly are `call-bind` and `get-intrinsic`.
-Please use `call-bind` unless you have a very good reason not to.
-
-## Getting started
-
-```sh
-npm install --save call-bind-apply-helpers
-```
-
-## Usage/Examples
-
-```js
-const assert = require('assert');
-const callBindBasic = require('call-bind-apply-helpers');
-
-function f(a, b) {
-	assert.equal(this, 1);
-	assert.equal(a, 2);
-	assert.equal(b, 3);
-	assert.equal(arguments.length, 2);
-}
-
-const fBound = callBindBasic([f, 1]);
-
-delete Function.prototype.call;
-delete Function.prototype.bind;
-
-fBound(2, 3);
-```
-
-## Tests
-
-Clone the repo, `npm install`, and run `npm test`

-## Usage/Examples
-
-```js
-const assert = require('assert');
-const callBound = require('call-bound');
-
-const slice = callBound('Array.prototype.slice');
-
-delete Function.prototype.call;
-delete Function.prototype.bind;
-delete Array.prototype.slice;
-
-assert.deepEqual(slice([1, 2, 3, 4], 1, -1), [2, 3]);
-```
-
-## Tests

-
-Create and parse HTTP `Content-Disposition` header
-
-## Installation
-
-```sh
-$ npm install content-disposition
-```
-
-## API
-
-```js
-const contentDisposition = require('content-disposition')
-```
-
-### contentDisposition(filename, options)
-
-Create an attachment `Content-Disposition` header value using the given file name,
-if supplied. The `filename` is optional and if no file name is desired, but you
-want to specify `options`, set `filename` to `undefined`.
-
-```js
-res.setHeader('Content-Disposition', contentDisposition('∫ maths.pdf'))
-```
-
-**note** HTTP headers are of the ISO-8859-1 character set. If you are writing this
-header through a means different from `setHeader` in Node.js, you'll want to specify
-the `'binary'` encoding in Node.js.
-
-#### Options
-
-`contentDisposition` accepts these properties in the options object.
-
-##### fallback
-
-If the `filename` option is outside ISO-8859-1, then the file name is actually
-stored in a supplemental field for clients that support Unicode file names and
-a ISO-8859-1 version of the file name is automatically generated.
-
-This specifies the ISO-8859-1 file name to override the automatic generation or
-disables the generation all together, defaults to `true`.
-
-  - A string will specify the ISO-8859-1 file name to use in place of automatic
-    generation.
-  - `false` will disable including a ISO-8859-1 file name and only include the
-    Unicode version (unless the file name is already ISO-8859-1).
-  - `true` will enable automatic generation if the file name is outside ISO-8859-1.
-
-If the `filename` option is ISO-8859-1 and this option is specified and has a
-different value, then the `filename` option is encoded in the extended field
-and this set as the fallback field, even though they are both ISO-8859-1.
-
-##### type
-
-Specifies the disposition type, defaults to `"attachment"`. This can also be
-`"inline"`, or any other value (all values except inline are treated like
-`attachment`, but can convey additional information if both parties agree to
-it). The type is normalized to lower-case.
-
-### contentDisposition.parse(string)
-
-```js
-const disposition = contentDisposition.parse('attachment; filename="EURO rates.txt"; filename*=UTF-8\'\'%e2%82%ac%20rates.txt')
-```
-
-Parse a `Content-Disposition` header string. This automatically handles extended
-("Unicode") parameters by decoding them and providing them under the standard
-parameter name. This will return an object with the following properties (examples
-are shown for the string `'attachment; filename="EURO rates.txt"; filename*=UTF-8\'\'%e2%82%ac%20rates.txt'`):
-
- - `type`: The disposition type (always lower case). Example: `'attachment'`
-
- - `parameters`: An object of the parameters in the disposition (name of parameter
-   always lower case and extended versions replace non-extended versions). Example:
-   `{filename: "€ rates.txt"}`
-
-## Examples
-
-### Send a file for download
-
-```js
-const contentDisposition = require('content-disposition')
-const destroy = require('destroy')
-const fs = require('fs')
-const http = require('http')
-const onFinished = require('on-finished')
-
-const filePath = '/path/to/public/plans.pdf'
-
-http.createServer(function onRequest (req, res) {
-  // set headers
-  res.setHeader('Content-Type', 'application/pdf')
-  res.setHeader('Content-Disposition', contentDisposition(filePath))
-
-  // send file
-  const stream = fs.createReadStream(filePath)
-  stream.pipe(res)
-  onFinished(res, function () {
-    destroy(stream)
-  })
-})
-```

-
-Create and parse HTTP Content-Type header according to RFC 7231
-
-## Installation
-
-```sh
-$ npm install content-type
-```
-
-## API
-
-```js
-var contentType = require('content-type')
-```
-
-### contentType.parse(string)
-
-```js
-var obj = contentType.parse('image/svg+xml; charset=utf-8')
-```
-
-Parse a `Content-Type` header. This will return an object with the following
-properties (examples are shown for the string `'image/svg+xml; charset=utf-8'`):
-
- - `type`: The media type (the type and subtype, always lower case).
-   Example: `'image/svg+xml'`
-
- - `parameters`: An object of the parameters in the media type (name of parameter
-   always lower case). Example: `{charset: 'utf-8'}`
-
-Throws a `TypeError` if the string is missing or invalid.
-
-### contentType.parse(req)
-
-```js
-var obj = contentType.parse(req)
-```
-
-Parse the `Content-Type` header from the given `req`. Short-cut for
-`contentType.parse(req.headers['content-type'])`.
-
-Throws a `TypeError` if the `Content-Type` header is missing or invalid.
-
-### contentType.parse(res)
-
-```js
-var obj = contentType.parse(res)
-```
-
-Parse the `Content-Type` header set on the given `res`. Short-cut for
-`contentType.parse(res.getHeader('content-type'))`.
-
-Throws a `TypeError` if the `Content-Type` header is missing or invalid.
-
-### contentType.format(obj)
-
-```js
-var str = contentType.format({
-  type: 'image/svg+xml',
-  parameters: { charset: 'utf-8' }
-})
-```
-
-Format an object into a `Content-Type` header. This will return a string of the
-content type for the given object with the following properties (examples are
-shown that produce the string `'image/svg+xml; charset=utf-8'`):
-
- - `type`: The media type (will be lower-cased). Example: `'image/svg+xml'`
-
- - `parameters`: An object of the parameters in the media type (name of the
-   parameter will be lower-cased). Example: `{charset: 'utf-8'}`
-
-Throws a `TypeError` if the object contains an invalid type or parameter names.

-
-Basic HTTP cookie parser and serializer for HTTP servers.
-
-## Installation
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install cookie
-```
-
-## API
-
-```js
-var cookie = require('cookie');
-```
-
-### cookie.parse(str, options)
-
-Parse an HTTP `Cookie` header string and returning an object of all cookie name-value pairs.
-The `str` argument is the string representing a `Cookie` header value and `options` is an
-optional object containing additional parsing options.
-
-```js
-var cookies = cookie.parse('foo=bar; equation=E%3Dmc%5E2');
-// { foo: 'bar', equation: 'E=mc^2' }
-```
-
-#### Options
-
-`cookie.parse` accepts these properties in the options object.
-
-##### decode
-
-Specifies a function that will be used to decode a cookie's value. Since the value of a cookie
-has a limited character set (and must be a simple string), this function can be used to decode
-a previously-encoded cookie value into a JavaScript string or other object.
-
-The default function is the global `decodeURIComponent`, which will decode any URL-encoded
-sequences into their byte representations.
-
-**note** if an error is thrown from this function, the original, non-decoded cookie value will
-be returned as the cookie's value.
-
-### cookie.serialize(name, value, options)
-
-Serialize a cookie name-value pair into a `Set-Cookie` header string. The `name` argument is the
-name for the cookie, the `value` argument is the value to set the cookie to, and the `options`
-argument is an optional object containing additional serialization options.
-
-```js
-var setCookie = cookie.serialize('foo', 'bar');
-// foo=bar
-```
-
-#### Options
-
-`cookie.serialize` accepts these properties in the options object.
-
-##### domain
-
-Specifies the value for the [`Domain` `Set-Cookie` attribute][rfc-6265-5.2.3]. By default, no
-domain is set, and most clients will consider the cookie to apply to only the current domain.
-
-##### encode
-
-Specifies a function that will be used to encode a cookie's value. Since value of a cookie
-has a limited character set (and must be a simple string), this function can be used to encode
-a value into a string suited for a cookie's value.
-
-The default function is the global `encodeURIComponent`, which will encode a JavaScript string
-into UTF-8 byte sequences and then URL-encode any that fall outside of the cookie range.
-
-##### expires
-
-Specifies the `Date` object to be the value for the [`Expires` `Set-Cookie` attribute][rfc-6265-5.2.1].
-By default, no expiration is set, and most clients will consider this a "non-persistent cookie" and
-will delete it on a condition like exiting a web browser application.
-
-**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and
-`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this,
-so if both are set, they should point to the same date and time.
-
-##### httpOnly
-
-Specifies the `boolean` value for the [`HttpOnly` `Set-Cookie` attribute][rfc-6265-5.2.6]. When truthy,
-the `HttpOnly` attribute is set, otherwise it is not. By default, the `HttpOnly` attribute is not set.
-
-**note** be careful when setting this to `true`, as compliant clients will not allow client-side
-JavaScript to see the cookie in `document.cookie`.
-
-##### maxAge
-
-Specifies the `number` (in seconds) to be the value for the [`Max-Age` `Set-Cookie` attribute][rfc-6265-5.2.2].
-The given number will be converted to an integer by rounding down. By default, no maximum age is set.
-
-**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and
-`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this,
-so if both are set, they should point to the same date and time.
-
-##### partitioned
-
-Specifies the `boolean` value for the [`Partitioned` `Set-Cookie`](rfc-cutler-httpbis-partitioned-cookies)
-attribute. When truthy, the `Partitioned` attribute is set, otherwise it is not. By default, the
-`Partitioned` attribute is not set.
-
-**note** This is an attribute that has not yet been fully standardized, and may change in the future.
-This also means many clients may ignore this attribute until they understand it.
-
-More information about can be found in [the proposal](https://github.com/privacycg/CHIPS).
-
-##### path
-
-Specifies the value for the [`Path` `Set-Cookie` attribute][rfc-6265-5.2.4]. By default, the path
-is considered the ["default path"][rfc-6265-5.1.4].
-
-##### priority
-
-Specifies the `string` to be the value for the [`Priority` `Set-Cookie` attribute][rfc-west-cookie-priority-00-4.1].
-
-  - `'low'` will set the `Priority` attribute to `Low`.
-  - `'medium'` will set the `Priority` attribute to `Medium`, the default priority when not set.
-  - `'high'` will set the `Priority` attribute to `High`.
-
-More information about the different priority levels can be found in
-[the specification][rfc-west-cookie-priority-00-4.1].
-
-**note** This is an attribute that has not yet been fully standardized, and may change in the future.
-This also means many clients may ignore this attribute until they understand it.
-
-##### sameSite
-
-Specifies the `boolean` or `string` to be the value for the [`SameSite` `Set-Cookie` attribute][rfc-6265bis-09-5.4.7].
-
-  - `true` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
-  - `false` will not set the `SameSite` attribute.
-  - `'lax'` will set the `SameSite` attribute to `Lax` for lax same site enforcement.
-  - `'none'` will set the `SameSite` attribute to `None` for an explicit cross-site cookie.
-  - `'strict'` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
-
-More information about the different enforcement levels can be found in
-[the specification][rfc-6265bis-09-5.4.7].
-
-**note** This is an attribute that has not yet been fully standardized, and may change in the future.
-This also means many clients may ignore this attribute until they understand it.
-
-##### secure
-
-Specifies the `boolean` value for the [`Secure` `Set-Cookie` attribute][rfc-6265-5.2.5]. When truthy,
-the `Secure` attribute is set, otherwise it is not. By default, the `Secure` attribute is not set.
-
-**note** be careful when setting this to `true`, as compliant clients will not send the cookie back to
-the server in the future if the browser does not have an HTTPS connection.
-
-## Example
-
-The following example uses this module in conjunction with the Node.js core HTTP server
-to prompt a user for their name and display it back on future visits.
-
-```js
-var cookie = require('cookie');
-var escapeHtml = require('escape-html');
-var http = require('http');
-var url = require('url');
-
-function onRequest(req, res) {
-  // Parse the query string
-  var query = url.parse(req.url, true, true).query;
-
-  if (query && query.name) {
-    // Set a new cookie with the name
-    res.setHeader('Set-Cookie', cookie.serialize('name', String(query.name), {
-      httpOnly: true,
-      maxAge: 60 * 60 * 24 * 7 // 1 week
-    }));
-
-    // Redirect back after setting cookie
-    res.statusCode = 302;
-    res.setHeader('Location', req.headers.referer || '/');
-    res.end();
-    return;
-  }
-
-  // Parse the cookies on the request
-  var cookies = cookie.parse(req.headers.cookie || '');
-
-  // Get the visitor name set in the cookie
-  var name = cookies.name;
-
-  res.setHeader('Content-Type', 'text/html; charset=UTF-8');
-
-  if (name) {
-    res.write('<p>Welcome back, <b>' + escapeHtml(name) + '</b>!</p>');
-  } else {
-    res.write('<p>Hello, new visitor!</p>');
-  }
-
-  res.write('<form method="GET">');
-  res.write('<input placeholder="enter your name" name="name"> <input type="submit" value="Set Name">');
-  res.end('</form>');

-http.createServer(onRequest).listen(3000);

-## Installation
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install cors
-```
-
-## Usage
-
-### Simple Usage (Enable *All* CORS Requests)
-
-```javascript
-var express = require('express')
-var cors = require('cors')
-var app = express()
-
-app.use(cors())
-
-app.get('/products/:id', function (req, res, next) {
-  res.json({msg: 'This is CORS-enabled for all origins!'})
-})
-
-app.listen(80, function () {
-  console.log('CORS-enabled web server listening on port 80')
-})
-```
-
-### Enable CORS for a Single Route
-
-```javascript
-var express = require('express')
-var cors = require('cors')
-var app = express()
-
-app.get('/products/:id', cors(), function (req, res, next) {
-  res.json({msg: 'This is CORS-enabled for a Single Route'})
-})
-
-app.listen(80, function () {
-  console.log('CORS-enabled web server listening on port 80')
-})
-```
-
-### Configuring CORS
-
-```javascript
-var express = require('express')
-var cors = require('cors')
-var app = express()
-
-var corsOptions = {
-  origin: 'http://example.com',
-  optionsSuccessStatus: 200 // some legacy browsers (IE11, various SmartTVs) choke on 204
-}
-
-app.get('/products/:id', cors(corsOptions), function (req, res, next) {
-  res.json({msg: 'This is CORS-enabled for only example.com.'})
-})
-
-app.listen(80, function () {
-  console.log('CORS-enabled web server listening on port 80')
-})
-```
-
-### Configuring CORS w/ Dynamic Origin
-
-```javascript
-var express = require('express')
-var cors = require('cors')
-var app = express()
-
-var whitelist = ['http://example1.com', 'http://example2.com']
-var corsOptions = {
-  origin: function (origin, callback) {
-    if (whitelist.indexOf(origin) !== -1) {
-      callback(null, true)
-    } else {
-      callback(new Error('Not allowed by CORS'))
-    }
-  }
-}
-
-app.get('/products/:id', cors(corsOptions), function (req, res, next) {
-  res.json({msg: 'This is CORS-enabled for a whitelisted domain.'})
-})
-
-app.listen(80, function () {
-  console.log('CORS-enabled web server listening on port 80')
-})
-```
-
-If you do not want to block REST tools or server-to-server requests,
-add a `!origin` check in the origin function like so:
-
-```javascript
-var corsOptions = {
-  origin: function (origin, callback) {
-    if (whitelist.indexOf(origin) !== -1 || !origin) {
-      callback(null, true)
-    } else {
-      callback(new Error('Not allowed by CORS'))
-    }
-  }
-}
-```
-
-### Enabling CORS Pre-Flight
-
-Certain CORS requests are considered 'complex' and require an initial
-`OPTIONS` request (called the "pre-flight request"). An example of a
-'complex' CORS request is one that uses an HTTP verb other than
-GET/HEAD/POST (such as DELETE) or that uses custom headers. To enable
-pre-flighting, you must add a new OPTIONS handler for the route you want
-to support:
-
-```javascript
-var express = require('express')
-var cors = require('cors')
-var app = express()
-
-app.options('/products/:id', cors()) // enable pre-flight request for DELETE request
-app.del('/products/:id', cors(), function (req, res, next) {
-  res.json({msg: 'This is CORS-enabled for all origins!'})
-})
-
-app.listen(80, function () {
-  console.log('CORS-enabled web server listening on port 80')
-})
-```
-
-You can also enable pre-flight across-the-board like so:
-
-```javascript
-app.options('*', cors()) // include before other routes
-```
-
-### Configuring CORS Asynchronously
-
-```javascript
-var express = require('express')
-var cors = require('cors')
-var app = express()
-
-var whitelist = ['http://example1.com', 'http://example2.com']
-var corsOptionsDelegate = function (req, callback) {
-  var corsOptions;
-  if (whitelist.indexOf(req.header('Origin')) !== -1) {
-    corsOptions = { origin: true } // reflect (enable) the requested origin in the CORS response
-  } else {
-    corsOptions = { origin: false } // disable CORS for this request
-  }
-  callback(null, corsOptions) // callback expects two parameters: error and options
-}
-
-app.get('/products/:id', cors(corsOptionsDelegate), function (req, res, next) {
-  res.json({msg: 'This is CORS-enabled for a whitelisted domain.'})
-})
-
-app.listen(80, function () {
-  console.log('CORS-enabled web server listening on port 80')
-})

-## Configuration Options
-
-* `origin`: Configures the **Access-Control-Allow-Origin** CORS header. Possible values:
-  - `Boolean` - set `origin` to `true` to reflect the [request origin](http://tools.ietf.org/html/draft-abarth-origin-09), as defined by `req.header('Origin')`, or set it to `false` to disable CORS.
-  - `String` - set `origin` to a specific origin. For example if you set it to `"http://example.com"` only requests from "http://example.com" will be allowed.
-  - `RegExp` - set `origin` to a regular expression pattern which will be used to test the request origin. If it's a match, the request origin will be reflected. For example the pattern `/example\.com$/` will reflect any request that is coming from an origin ending with "example.com".
-  - `Array` - set `origin` to an array of valid origins. Each origin can be a `String` or a `RegExp`. For example `["http://example1.com", /\.example2\.com$/]` will accept any request from "http://example1.com" or from a subdomain of "example2.com".
-  - `Function` - set `origin` to a function implementing some custom logic. The function takes the request origin as the first parameter and a callback (which expects the signature `err [object], allow [bool]`) as the second.
-* `methods`: Configures the **Access-Control-Allow-Methods** CORS header. Expects a comma-delimited string (ex: 'GET,PUT,POST') or an array (ex: `['GET', 'PUT', 'POST']`).
-* `allowedHeaders`: Configures the **Access-Control-Allow-Headers** CORS header. Expects a comma-delimited string (ex: 'Content-Type,Authorization') or an array (ex: `['Content-Type', 'Authorization']`). If not specified, defaults to reflecting the headers specified in the request's **Access-Control-Request-Headers** header.
-* `exposedHeaders`: Configures the **Access-Control-Expose-Headers** CORS header. Expects a comma-delimited string (ex: 'Content-Range,X-Content-Range') or an array (ex: `['Content-Range', 'X-Content-Range']`). If not specified, no custom headers are exposed.
-* `credentials`: Configures the **Access-Control-Allow-Credentials** CORS header. Set to `true` to pass the header, otherwise it is omitted.
-* `maxAge`: Configures the **Access-Control-Max-Age** CORS header. Set to an integer to pass the header, otherwise it is omitted.
-* `preflightContinue`: Pass the CORS preflight response to the next handler.
-* `optionsSuccessStatus`: Provides a status code to use for successful `OPTIONS` requests, since some legacy browsers (IE11, various SmartTVs) choke on `204`.
-
-The default configuration is the equivalent of:
-
-```json
-{
-  "origin": "*",
-  "methods": "GET,HEAD,PUT,PATCH,POST,DELETE",
-  "preflightContinue": false,
-  "optionsSuccessStatus": 204
-}
-```
-
-For details on the effect of each CORS header, read [this](http://www.html5rocks.com/en/tutorials/cors/) article on HTML5 Rocks.
-
-## Demo
-
-A demo that illustrates CORS working (and not working) using jQuery is available here: [http://node-cors-client.herokuapp.com/](http://node-cors-client.herokuapp.com/)

-
-A tiny JavaScript debugging utility modelled after Node.js core's debugging
-technique. Works in Node.js and web browsers.
-
-## Installation
-
-```bash
-$ npm install debug
-```
-
-## Usage
-
-`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
-
-Example [_app.js_](./examples/node/app.js):
-
-```js
-var debug = require('debug')('http')
-  , http = require('http')
-  , name = 'My App';
-
-// fake app
-
-debug('booting %o', name);
-
-http.createServer(function(req, res){
-  debug(req.method + ' ' + req.url);
-  res.end('hello\n');
-}).listen(3000, function(){
-  debug('listening');
-});
-
-// fake worker of some kind
-
-require('./worker');
-```
-
-Example [_worker.js_](./examples/node/worker.js):
-
-```js
-var a = require('debug')('worker:a')
-  , b = require('debug')('worker:b');
-
-function work() {
-  a('doing lots of uninteresting work');
-  setTimeout(work, Math.random() * 1000);
-}
-
-work();
-
-function workb() {
-  b('doing some work');
-  setTimeout(workb, Math.random() * 2000);
-}
-
-workb();
-```
-
-The `DEBUG` environment variable is then used to enable these based on space or
-comma-delimited names.
-
-Here are some examples:
-
-<img width="647" alt="screen shot 2017-08-08 at 12 53 04 pm" src="https://user-images.githubusercontent.com/71256/29091703-a6302cdc-7c38-11e7-8304-7c0b3bc600cd.png">
-<img width="647" alt="screen shot 2017-08-08 at 12 53 38 pm" src="https://user-images.githubusercontent.com/71256/29091700-a62a6888-7c38-11e7-800b-db911291ca2b.png">

-
-#### Windows command prompt notes
-
-##### CMD
-
-On Windows the environment variable is set using the `set` command.
-
-```cmd
-set DEBUG=*,-not_this
-```
-
-Example:
-
-```cmd
-set DEBUG=* & node app.js
-```
-
-##### PowerShell (VS Code default)
-
-PowerShell uses different syntax to set environment variables.
-
-```cmd
-$env:DEBUG = "*,-not_this"
-```
-
-Example:
-
-```cmd
-$env:DEBUG='app';node app.js
-```
-
-Then, run the program to be debugged as usual.
-
-npm script example:
-```js
-  "windowsDebug": "@powershell -Command $env:DEBUG='*';node app.js",
-```
-
-## Namespace Colors
-
-Every debug instance has a color generated for it based on its namespace name.
-This helps when visually parsing the debug output to identify which debug instance
-a debug line belongs to.
-
-#### Node.js
-
-In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
-the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
-otherwise debug will only use a small handful of basic colors.
-
-<img width="521" src="https://user-images.githubusercontent.com/71256/29092181-47f6a9e6-7c3a-11e7-9a14-1928d8a711cd.png">
-
-#### Web Browser
-
-Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
-option. These are WebKit web inspectors, Firefox ([since version
-31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
-and the Firebug plugin for Firefox (any version).
-
-<img width="524" src="https://user-images.githubusercontent.com/71256/29092033-b65f9f2e-7c39-11e7-8e32-f6f0d8e865c1.png">
-
-
-## Millisecond diff
-
-When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
-
-<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
-
-When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
-
-<img width="647" src="https://user-images.githubusercontent.com/71256/29091956-6bd78372-7c39-11e7-8c55-c948396d6edd.png">
-
-
-## Conventions
-
-If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser".  If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable.  You can then use it for normal output as well as debug output.
-
-## Wildcards
-
-The `*` character may be used as a wildcard. Suppose for example your library has
-debuggers named "connect:bodyParser", "connect:compress", "connect:session",
-instead of listing all three with
-`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
-`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
-
-You can also exclude specific debuggers by prefixing them with a "-" character.
-For example, `DEBUG=*,-connect:*` would include all debuggers except those
-starting with "connect:".
-
-## Environment Variables
-
-When running through Node.js, you can set a few environment variables that will
-change the behavior of the debug logging:
-
-| Name      | Purpose                                         |
-|-----------|-------------------------------------------------|
-| `DEBUG`   | Enables/disables specific debugging namespaces. |
-| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY).  |
-| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
-| `DEBUG_DEPTH` | Object inspection depth.                    |
-| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
-
-
-__Note:__ The environment variables beginning with `DEBUG_` end up being
-converted into an Options object that gets used with `%o`/`%O` formatters.
-See the Node.js documentation for
-[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
-for the complete list.
-
-## Formatters
-
-Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
-Below are the officially supported formatters:
-
-| Formatter | Representation |
-|-----------|----------------|
-| `%O`      | Pretty-print an Object on multiple lines. |
-| `%o`      | Pretty-print an Object all on a single line. |
-| `%s`      | String. |
-| `%d`      | Number (both integer and float). |
-| `%j`      | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
-| `%%`      | Single percent sign ('%'). This does not consume an argument. |
-
-
-### Custom formatters
-
-You can add custom formatters by extending the `debug.formatters` object.
-For example, if you wanted to add support for rendering a Buffer as hex with
-`%h`, you could do something like:
-
-```js
-const createDebug = require('debug')
-createDebug.formatters.h = (v) => {
-  return v.toString('hex')
-}
-
-// …elsewhere
-const debug = createDebug('foo')
-debug('this is hex: %h', new Buffer('hello world'))
-//   foo this is hex: 68656c6c6f20776f726c6421 +0ms
-```
-
-
-## Browser Support
-
-You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
-or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
-if you don't want to build it yourself.
-
-Debug's enable state is currently persisted by `localStorage`.
-Consider the situation shown below where you have `worker:a` and `worker:b`,
-and wish to debug both. You can enable this using `localStorage.debug`:
-
-```js
-localStorage.debug = 'worker:*'
-```
-
-And then refresh the page.
-
-```js
-a = debug('worker:a');
-b = debug('worker:b');
-
-setInterval(function(){
-  a('doing some work');
-}, 1000);
-
-setInterval(function(){
-  b('doing some work');
-}, 1200);
-```
-
-In Chromium-based web browsers (e.g. Brave, Chrome, and Electron), the JavaScript console will—by default—only show messages logged by `debug` if the "Verbose" log level is _enabled_.

-
-## Output streams
-
-  By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
-
-Example [_stdout.js_](./examples/node/stdout.js):
-
-```js
-var debug = require('debug');
-var error = debug('app:error');
-
-// by default stderr is used
-error('goes to stderr!');
-
-var log = debug('app:log');
-// set this namespace to log via console.log
-log.log = console.log.bind(console); // don't forget to bind to console!
-log('goes to stdout');
-error('still goes to stderr!');
-
-// set all output to go via console.info
-// overrides all per-namespace log settings
-debug.log = console.info.bind(console);
-error('now goes to stdout via console.info');
-log('still goes to stdout, but via console.info now');
-```
-
-## Extend
-You can simply extend debugger 
-```js
-const log = require('debug')('auth');
-
-//creates new debug instance with extended namespace
-const logSign = log.extend('sign');
-const logLogin = log.extend('login');
-
-log('hello'); // auth hello
-logSign('hello'); //auth:sign hello
-logLogin('hello'); //auth:login hello
-```
-
-## Set dynamically
-
-You can also enable debug dynamically by calling the `enable()` method :
-
-```js
-let debug = require('debug');
-
-console.log(1, debug.enabled('test'));
-
-debug.enable('test');
-console.log(2, debug.enabled('test'));
-
-debug.disable();
-console.log(3, debug.enabled('test'));
-
-```
-
-print :   
-```
-1 false
-2 true
-3 false
-```
-
-Usage :  
-`enable(namespaces)`  
-`namespaces` can include modes separated by a colon and wildcards.
-   
-Note that calling `enable()` completely overrides previously set DEBUG variable : 
-
-```
-$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))'
-=> false
-```
-
-`disable()`
-
-Will disable all namespaces. The functions returns the namespaces currently
-enabled (and skipped). This can be useful if you want to disable debugging
-temporarily without knowing what was enabled to begin with.
-
-For example:
-
-```js
-let debug = require('debug');
-debug.enable('foo:*,-foo:bar');
-let namespaces = debug.disable();
-debug.enable(namespaces);
-```
-
-Note: There is no guarantee that the string will be identical to the initial
-enable string, but semantically they will be identical.
-
-## Checking whether a debug target is enabled
-
-After you've created a debug instance, you can determine whether or not it is
-enabled by checking the `enabled` property:
-
-```javascript
-const debug = require('debug')('http');
-
-if (debug.enabled) {
-  // do stuff...
-}
-```
-
-You can also manually toggle this property to force the debug instance to be
-enabled or disabled.
-
-## Usage in child processes
-
-Due to the way `debug` detects if the output is a TTY or not, colors are not shown in child processes when `stderr` is piped. A solution is to pass the `DEBUG_COLORS=1` environment variable to the child process.  
-For example:
-
-```javascript
-worker = fork(WORKER_WRAP_PATH, [workerPath], {
-  stdio: [
-    /* stdin: */ 0,
-    /* stdout: */ 'pipe',
-    /* stderr: */ 'pipe',
-    'ipc',
-  ],
-  env: Object.assign({}, process.env, {
-    DEBUG_COLORS: 1 // without this settings, colors won't be shown
-  }),
-});
-
-worker.stderr.pipe(process.stderr, { end: false });
-```

-Deprecate all the things
-
-> With great modules comes great responsibility; mark things deprecated!
-
-## Install
-
-This module is installed directly using `npm`:
-
-```sh
-$ npm install depd
-```
-
-This module can also be bundled with systems like
-[Browserify](http://browserify.org/) or [webpack](https://webpack.github.io/),
-though by default this module will alter it's API to no longer display or
-track deprecations.
-
-## API
-
-<!-- eslint-disable no-unused-vars -->
-
-```js
-var deprecate = require('depd')('my-module')
-```
-
-This library allows you to display deprecation messages to your users.
-This library goes above and beyond with deprecation warnings by
-introspection of the call stack (but only the bits that it is interested
-in).
-
-Instead of just warning on the first invocation of a deprecated
-function and never again, this module will warn on the first invocation
-of a deprecated function per unique call site, making it ideal to alert
-users of all deprecated uses across the code base, rather than just
-whatever happens to execute first.
-
-The deprecation warnings from this module also include the file and line
-information for the call into the module that the deprecated function was
-in.
-
-**NOTE** this library has a similar interface to the `debug` module, and
-this module uses the calling file to get the boundary for the call stacks,
-so you should always create a new `deprecate` object in each file and not
-within some central file.
-
-### depd(namespace)
-
-Create a new deprecate function that uses the given namespace name in the
-messages and will display the call site prior to the stack entering the
-file this function was called from. It is highly suggested you use the
-name of your module as the namespace.
-
-### deprecate(message)
-
-Call this function from deprecated code to display a deprecation message.
-This message will appear once per unique caller site. Caller site is the
-first call site in the stack in a different file from the caller of this
-function.
-
-If the message is omitted, a message is generated for you based on the site
-of the `deprecate()` call and will display the name of the function called,
-similar to the name displayed in a stack trace.
-
-### deprecate.function(fn, message)
-
-Call this function to wrap a given function in a deprecation message on any
-call to the function. An optional message can be supplied to provide a custom
-message.
-
-### deprecate.property(obj, prop, message)
-
-Call this function to wrap a given property on object in a deprecation message
-on any accessing or setting of the property. An optional message can be supplied
-to provide a custom message.
-
-The method must be called on the object where the property belongs (not
-inherited from the prototype).
-
-If the property is a data descriptor, it will be converted to an accessor
-descriptor in order to display the deprecation message.
-
-### process.on('deprecation', fn)
-
-This module will allow easy capturing of deprecation errors by emitting the
-errors as the type "deprecation" on the global `process`. If there are no
-listeners for this type, the errors are written to STDERR as normal, but if
-there are any listeners, nothing will be written to STDERR and instead only
-emitted. From there, you can write the errors in a different format or to a
-logging source.
-
-The error represents the deprecation and is emitted only once with the same
-rules as writing to STDERR. The error has the following properties:
-
-  - `message` - This is the message given by the library
-  - `name` - This is always `'DeprecationError'`
-  - `namespace` - This is the namespace the deprecation came from
-  - `stack` - This is the stack of the call to the deprecated thing
-
-Example `error.stack` output:
-
-```
-DeprecationError: my-cool-module deprecated oldfunction
-    at Object.<anonymous> ([eval]-wrapper:6:22)
-    at Module._compile (module.js:456:26)
-    at evalScript (node.js:532:25)
-    at startup (node.js:80:7)
-    at node.js:902:3
-```
-
-### process.env.NO_DEPRECATION
-
-As a user of modules that are deprecated, the environment variable `NO_DEPRECATION`
-is provided as a quick solution to silencing deprecation warnings from being
-output. The format of this is similar to that of `DEBUG`:
-
-```sh
-$ NO_DEPRECATION=my-module,othermod node app.js
-```
-
-This will suppress deprecations from being output for "my-module" and "othermod".
-The value is a list of comma-separated namespaces. To suppress every warning
-across all namespaces, use the value `*` for a namespace.
-
-Providing the argument `--no-deprecation` to the `node` executable will suppress
-all deprecations (only available in Node.js 0.8 or higher).
-
-**NOTE** This will not suppress the deperecations given to any "deprecation"
-event listeners, just the output to STDERR.
-
-### process.env.TRACE_DEPRECATION
-
-As a user of modules that are deprecated, the environment variable `TRACE_DEPRECATION`
-is provided as a solution to getting more detailed location information in deprecation
-warnings by including the entire stack trace. The format of this is the same as
-`NO_DEPRECATION`:
-
-```sh
-$ TRACE_DEPRECATION=my-module,othermod node app.js
-```
-
-This will include stack traces for deprecations being output for "my-module" and
-"othermod". The value is a list of comma-separated namespaces. To trace every
-warning across all namespaces, use the value `*` for a namespace.
-
-Providing the argument `--trace-deprecation` to the `node` executable will trace
-all deprecations (only available in Node.js 0.8 or higher).
-
-**NOTE** This will not trace the deperecations silenced by `NO_DEPRECATION`.
-
-## Display
-
-![message](files/message.png)
-
-When a user calls a function in your library that you mark deprecated, they
-will see the following written to STDERR (in the given colors, similar colors
-and layout to the `debug` module):
-
-```
-bright cyan    bright yellow
-|              |          reset       cyan
-|              |          |           |
-▼              ▼          ▼           ▼
-my-cool-module deprecated oldfunction [eval]-wrapper:6:22
-▲              ▲          ▲           ▲
-|              |          |           |
-namespace      |          |           location of mycoolmod.oldfunction() call
-               |          deprecation message
-               the word "deprecated"
-```
-
-If the user redirects their STDERR to a file or somewhere that does not support
-colors, they see (similar layout to the `debug` module):
-
-```
-Sun, 15 Jun 2014 05:21:37 GMT my-cool-module deprecated oldfunction at [eval]-wrapper:6:22
-▲                             ▲              ▲          ▲              ▲
-|                             |              |          |              |
-timestamp of message          namespace      |          |             location of mycoolmod.oldfunction() call
-                                             |          deprecation message
-                                             the word "deprecated"
-```
-
-## Examples
-
-### Deprecating all calls to a function
-
-This will display a deprecated message about "oldfunction" being deprecated
-from "my-module" on STDERR.
-
-```js
-var deprecate = require('depd')('my-cool-module')
-
-// message automatically derived from function name
-// Object.oldfunction
-exports.oldfunction = deprecate.function(function oldfunction () {
-  // all calls to function are deprecated
-})
-
-// specific message
-exports.oldfunction = deprecate.function(function () {
-  // all calls to function are deprecated
-}, 'oldfunction')
-```
-
-### Conditionally deprecating a function call
-
-This will display a deprecated message about "weirdfunction" being deprecated
-from "my-module" on STDERR when called with less than 2 arguments.
-
-```js
-var deprecate = require('depd')('my-cool-module')
-
-exports.weirdfunction = function () {
-  if (arguments.length < 2) {
-    // calls with 0 or 1 args are deprecated
-    deprecate('weirdfunction args < 2')
-  }
-}
-```
-
-When calling `deprecate` as a function, the warning is counted per call site
-within your own module, so you can display different deprecations depending
-on different situations and the users will still get all the warnings:
-
-```js
-var deprecate = require('depd')('my-cool-module')
-
-exports.weirdfunction = function () {
-  if (arguments.length < 2) {
-    // calls with 0 or 1 args are deprecated
-    deprecate('weirdfunction args < 2')
-  } else if (typeof arguments[0] !== 'string') {
-    // calls with non-string first argument are deprecated
-    deprecate('weirdfunction non-string first arg')
-  }
-}
-```
-
-### Deprecating property access
-
-This will display a deprecated message about "oldprop" being deprecated
-from "my-module" on STDERR when accessed. A deprecation will be displayed
-when setting the value and when getting the value.
-
-```js
-var deprecate = require('depd')('my-cool-module')
-
-exports.oldprop = 'something'
-
-// message automatically derives from property name
-deprecate.property(exports, 'oldprop')
-
-// explicit message
-deprecate.property(exports, 'oldprop', 'oldprop >= 0.10')
-```

-Get the first event in a set of event emitters and event pairs,
-then clean up after itself.
-
-## Install
-
-```sh
-$ npm install ee-first
-```
-
-## API
-
-```js
-var first = require('ee-first')
-```
-
-### first(arr, listener)
-
-Invoke `listener` on the first event from the list specified in `arr`. `arr` is
-an array of arrays, with each array in the format `[ee, ...event]`. `listener`
-will be called only once, the first time any of the given events are emitted. If
-`error` is one of the listened events, then if that fires first, the `listener`
-will be given the `err` argument.
-
-The `listener` is invoked as `listener(err, ee, event, args)`, where `err` is the
-first argument emitted from an `error` event, if applicable; `ee` is the event
-emitter that fired; `event` is the string event name that fired; and `args` is an
-array of the arguments that were emitted on the event.
-
-```js
-var ee1 = new EventEmitter()
-var ee2 = new EventEmitter()
-
-first([
-  [ee1, 'close', 'end', 'error'],
-  [ee2, 'error']
-], function (err, ee, event, args) {
-  // listener invoked
-})
-```
-
-#### .cancel()
-
-The group of listeners can be cancelled before being invoked and have all the event
-listeners removed from the underlying event emitters.
-
-```js
-var thunk = first([
-  [ee1, 'close', 'end', 'error'],
-  [ee2, 'error']
-], function (err, ee, event, args) {
-  // listener invoked
-})
-
-// cancel and clean up
-thunk.cancel()
-```

-# Encode URL
-
-Encode a URL to a percent-encoded form, excluding already-encoded sequences.
-
-## Installation
-
-```sh
-npm install encodeurl
-```
-
-## API
-
-```js
-var encodeUrl = require('encodeurl')
-```
-
-### encodeUrl(url)
-
-Encode a URL to a percent-encoded form, excluding already-encoded sequences.
-
-This function accepts a URL and encodes all the non-URL code points (as UTF-8 byte sequences). It will not encode the "%" character unless it is not part of a valid sequence (`%20` will be left as-is, but `%foo` will be encoded as `%25foo`).
-
-This encode is meant to be "safe" and does not throw errors. It will try as hard as it can to properly encode the given URL, including replacing any raw, unpaired surrogate pairs with the Unicode replacement character prior to encoding.
-
-## Examples
-
-### Encode a URL containing user-controlled data
-
-```js
-var encodeUrl = require('encodeurl')
-var escapeHtml = require('escape-html')
-
-http.createServer(function onRequest (req, res) {
-  // get encoded form of inbound url
-  var url = encodeUrl(req.url)
-
-  // create html message
-  var body = '<p>Location ' + escapeHtml(url) + ' not found</p>'
-
-  // send a 404
-  res.statusCode = 404
-  res.setHeader('Content-Type', 'text/html; charset=UTF-8')
-  res.setHeader('Content-Length', String(Buffer.byteLength(body, 'utf-8')))
-  res.end(body, 'utf-8')
-})
-```
-
-### Encode a URL for use in a header field
-
-```js
-var encodeUrl = require('encodeurl')
-var escapeHtml = require('escape-html')
-var url = require('url')
-
-http.createServer(function onRequest (req, res) {
-  // parse inbound url
-  var href = url.parse(req)
-
-  // set new host for redirect
-  href.host = 'localhost'
-  href.protocol = 'https:'
-  href.slashes = true
-
-  // create location header
-  var location = encodeUrl(url.format(href))
-
-  // create html message
-  var body = '<p>Redirecting to new site: ' + escapeHtml(location) + '</p>'
-
-  // send a 301
-  res.statusCode = 301
-  res.setHeader('Content-Type', 'text/html; charset=UTF-8')
-  res.setHeader('Content-Length', String(Buffer.byteLength(body, 'utf-8')))
-  res.setHeader('Location', location)
-  res.end(body, 'utf-8')
-})
-```
-
-## Similarities
-
-This function is _similar_ to the intrinsic function `encodeURI`. However, it will not encode:
-
-* The `\`, `^`, or `|` characters
-* The `%` character when it's part of a valid sequence
-* `[` and `]` (for IPv6 hostnames)
-* Replaces raw, unpaired surrogate pairs with the Unicode replacement character
-
-As a result, the encoding aligns closely with the behavior in the [WHATWG URL specification][whatwg-url]. However, this package only encodes strings and does not do any URL parsing or formatting.
-
-It is expected that any output from `new URL(url)` will not change when used with this package, as the output has already been encoded. Additionally, if we were to encode before `new URL(url)`, we do not expect the before and after encoded formats to be parsed any differently.
-
-## Testing
-
-```sh
-$ npm test
-$ npm run lint
-```

-
-Create simple HTTP ETags
-
-This module generates HTTP ETags (as defined in RFC 7232) for use in
-HTTP responses.
-
-## Installation
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install etag
-```
-
-## API
-
-<!-- eslint-disable no-unused-vars -->
-
-```js
-var etag = require('etag')
-```
-
-### etag(entity, [options])
-
-Generate a strong ETag for the given entity. This should be the complete
-body of the entity. Strings, `Buffer`s, and `fs.Stats` are accepted. By
-default, a strong ETag is generated except for `fs.Stats`, which will
-generate a weak ETag (this can be overwritten by `options.weak`).
-
-<!-- eslint-disable no-undef -->
-
-```js
-res.setHeader('ETag', etag(body))
-```
-
-#### Options
-
-`etag` accepts these properties in the options object.
-
-##### weak
-
-Specifies if the generated ETag will include the weak validator mark (that
-is, the leading `W/`). The actual entity tag is the same. The default value
-is `false`, unless the `entity` is `fs.Stats`, in which case it is `true`.
-

-```js
-import express from 'express'
-
-const app = express()
-
-app.get('/', (req, res) => {
-  res.send('Hello World')
-})
-
-app.listen(3000, () => {
-  console.log('Server is running on http://localhost:3000')
-})
-```
-
-## Installation
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/).
-
-Before installing, [download and install Node.js](https://nodejs.org/en/download/).
-Node.js 18 or higher is required.
-
-If this is a brand new project, make sure to create a `package.json` first with
-the [`npm init` command](https://docs.npmjs.com/creating-a-package-json-file).
-
-Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```bash
-npm install express
-```
-
-Follow [our installing guide](https://expressjs.com/en/starter/installing.html)
-for more information.
-
-## Features
-
-  * Robust routing
-  * Focus on high performance
-  * Super-high test coverage
-  * HTTP helpers (redirection, caching, etc)
-  * View system supporting 14+ template engines
-  * Content negotiation
-  * Executable for generating applications quickly
-
-## Docs & Community
-
-  * [Website and Documentation](https://expressjs.com/) - [[website repo](https://github.com/expressjs/expressjs.com)]
-  * [GitHub Organization](https://github.com/expressjs) for Official Middleware & Modules
-  * [Github Discussions](https://github.com/expressjs/discussions) for discussion on the development and usage of Express
-
-**PROTIP** Be sure to read the [migration guide to v5](https://expressjs.com/en/guide/migrating-5)
-
-## Quick Start
-
-  The quickest way to get started with express is to utilize the executable [`express(1)`](https://github.com/expressjs/generator) to generate an application as shown below:
-
-  Install the executable. The executable's major version will match Express's:
-
-```bash
-npm install -g express-generator@4
-```
-
-  Create the app:
-
-```bash
-express /tmp/foo && cd /tmp/foo
-```
-
-  Install dependencies:
-
-```bash
-npm install
-```
-
-  Start the server:
-
-```bash
-npm start
-```
-
-  View the website at: http://localhost:3000
-
-## Philosophy
-
-  The Express philosophy is to provide small, robust tooling for HTTP servers, making
-  it a great solution for single page applications, websites, hybrids, or public
-  HTTP APIs.
-
-  Express does not force you to use any specific ORM or template engine. With support for over
-  14 template engines via [@ladjs/consolidate](https://github.com/ladjs/consolidate),
-  you can quickly craft your perfect framework.
-
-## Examples
-
-  To view the examples, clone the Express repository:
-
-```bash
-git clone https://github.com/expressjs/express.git --depth 1 && cd express
-```
-
-  Then install the dependencies:
-
-```bash
-npm install
-```
-
-  Then run whichever example you want:
-
-```bash
-node examples/content-negotiation
-```
-
-## Contributing
-
-The Express.js project welcomes all constructive contributions. Contributions take many forms,
-from code for bug fixes and enhancements, to additions and fixes to documentation, additional
-tests, triaging incoming pull requests and issues, and more!
-
-See the [Contributing Guide] for more technical details on contributing.
-
-### Security Issues
-
-If you discover a security vulnerability in Express, please see [Security Policies and Procedures](SECURITY.md).
-
-### Running Tests
-
-To run the test suite, first install the dependencies:
-
-```bash
-npm install
-```
-
-Then run `npm test`:
-
-```bash
-npm test
-```

- *
- * For engines that do not provide `.__express` out of the box,

- * you may use this method. For example mapping the EJS template engine to
- * ".html" files:
- *
- *     app.engine('html', require('ejs').renderFile);
- *
- * In this case EJS provides a `.renderFile()` method with

- * though note that it aliases this method as `ejs.__express` internally
- * so if you're using ".ejs" extensions you don't need to do anything.
- *
- * Some template engines do not follow this convention, the
- * [Consolidate.js](https://github.com/tj/consolidate.js)
- * library was created to map all of node's popular template
- * engines to follow this convention, thus allowing them to
- * work seamlessly within Express.

-Node.js function to invoke as the final step to respond to HTTP request.
-
-## Installation
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install finalhandler
-```
-
-## API
-
-```js
-const finalhandler = require('finalhandler')
-```
-
-### finalhandler(req, res, [options])
-
-Returns function to be invoked as the final step for the given `req` and `res`.
-This function is to be invoked as `fn(err)`. If `err` is falsy, the handler will
-write out a 404 response to the `res`. If it is truthy, an error response will
-be written out to the `res` or `res` will be terminated if a response has already
-started.
-
-When an error is written, the following information is added to the response:
-
-  * The `res.statusCode` is set from `err.status` (or `err.statusCode`). If
-    this value is outside the 4xx or 5xx range, it will be set to 500.
-  * The `res.statusMessage` is set according to the status code.
-  * The body will be the HTML of the status code message if `env` is
-    `'production'`, otherwise will be `err.stack`.
-  * Any headers specified in an `err.headers` object.
-
-The final handler will also unpipe anything from `req` when it is invoked.
-
-#### options.env
-
-By default, the environment is determined by `NODE_ENV` variable, but it can be
-overridden by this option.
-
-#### options.onerror
-
-Provide a function to be called with the `err` when it exists. Can be used for
-writing errors to a central location without excessive function generation. Called
-as `onerror(err, req, res)`.
-
-## Examples
-
-### always 404
-
-```js
-const finalhandler = require('finalhandler')
-const http = require('http')
-
-const server = http.createServer((req, res) => {
-  const done = finalhandler(req, res)
-  done()
-})
-
-server.listen(3000)
-```
-
-### perform simple action
-
-```js
-const finalhandler = require('finalhandler')
-const fs = require('fs')
-const http = require('http')
-
-const server = http.createServer((req, res) => {
-  const done = finalhandler(req, res)
-
-  fs.readFile('index.html', (err, buf) => {
-    if (err) return done(err)
-    res.setHeader('Content-Type', 'text/html')
-    res.end(buf)
-  })
-})
-
-server.listen(3000)
-```
-
-### use with middleware-style functions
-
-```js
-const finalhandler = require('finalhandler')
-const http = require('http')
-const serveStatic = require('serve-static')
-
-const serve = serveStatic('public')
-
-const server = http.createServer((req, res) => {
-  const done = finalhandler(req, res)
-  serve(req, res, done)
-})
-
-server.listen(3000)
-```
-
-### keep log of all errors
-
-```js
-const finalhandler = require('finalhandler')
-const fs = require('fs')
-const http = require('http')
-
-const server = http.createServer((req, res) => {
-  const done = finalhandler(req, res, { onerror: logerror })
-
-  fs.readFile('index.html', (err, buf) => {
-    if (err) return done(err)
-    res.setHeader('Content-Type', 'text/html')
-    res.end(buf)
-  })
-})
-
-server.listen(3000)
-
-function logerror (err) {
-  console.error(err.stack || err.toString())
-}
-```

-Parse HTTP X-Forwarded-For header
-
-## Installation
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install forwarded
-```
-
-## API
-
-```js
-var forwarded = require('forwarded')
-```
-
-### forwarded(req)
-
-```js
-var addresses = forwarded(req)
-```
-
-Parse the `X-Forwarded-For` header from the request. Returns an array
-of the addresses, including the socket address for the `req`, in reverse
-order (i.e. index `0` is the socket address and the last index is the
-furthest address, typically the end-user).

-HTTP response freshness testing
-
-## Installation
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```
-$ npm install fresh
-```
-
-## API
-
-```js
-var fresh = require('fresh')
-```
-
-### fresh(reqHeaders, resHeaders)
-
-Check freshness of the response using request and response headers.
-
-When the response is still "fresh" in the client's cache `true` is
-returned, otherwise `false` is returned to indicate that the client
-cache is now stale and the full response should be sent.
-
-When a client sends the `Cache-Control: no-cache` request header to
-indicate an end-to-end reload request, this module will return `false`
-to make handling these requests transparent.
-
-## Known Issues
-
-This module is designed to only follow the HTTP specifications, not
-to work-around all kinda of client bugs (especially since this module
-typically does not receive enough information to understand what the
-client actually is).
-
-There is a known issue that in certain versions of Safari, Safari
-will incorrectly make a request that allows this module to validate
-freshness of the resource even when Safari does not have a
-representation of the resource in the cache. The module
-[jumanji](https://www.npmjs.com/package/jumanji) can be used in
-an Express application to work-around this issue and also provides
-links to further reading on this Safari bug.
-
-## Example
-
-### API usage
-
-<!-- eslint-disable no-redeclare -->
-
-```js
-var reqHeaders = { 'if-none-match': '"foo"' }
-var resHeaders = { etag: '"bar"' }
-fresh(reqHeaders, resHeaders)
-// => false
-
-var reqHeaders = { 'if-none-match': '"foo"' }
-var resHeaders = { etag: '"foo"' }
-fresh(reqHeaders, resHeaders)
-// => true
-```
-
-### Using with Node.js http server
-
-```js
-var fresh = require('fresh')
-var http = require('http')
-
-var server = http.createServer(function (req, res) {
-  // perform server logic
-  // ... including adding ETag / Last-Modified response headers
-
-  if (isFresh(req, res)) {
-    // client has a fresh copy of resource
-    res.statusCode = 304
-    res.end()
-    return
-  }
-
-  // send the resource
-  res.statusCode = 200
-  res.end('hello, world!')
-})
-
-function isFresh (req, res) {
-  return fresh(req.headers, {
-    etag: res.getHeader('ETag'),
-    'last-modified': res.getHeader('Last-Modified')
-  })
-}
-
-server.listen(3000)
-```

-Get and robustly cache all JS language-level intrinsics at first require time.
-
-See the syntax described [in the JS spec](https://tc39.es/ecma262/#sec-well-known-intrinsic-objects) for reference.
-
-## Example
-
-```js
-var GetIntrinsic = require('get-intrinsic');
-var assert = require('assert');
-
-// static methods
-assert.equal(GetIntrinsic('%Math.pow%'), Math.pow);
-assert.equal(Math.pow(2, 3), 8);
-assert.equal(GetIntrinsic('%Math.pow%')(2, 3), 8);
-delete Math.pow;
-assert.equal(GetIntrinsic('%Math.pow%')(2, 3), 8);
-
-// instance methods
-var arr = [1];
-assert.equal(GetIntrinsic('%Array.prototype.push%'), Array.prototype.push);
-assert.deepEqual(arr, [1]);
-
-arr.push(2);
-assert.deepEqual(arr, [1, 2]);
-
-GetIntrinsic('%Array.prototype.push%').call(arr, 3);
-assert.deepEqual(arr, [1, 2, 3]);
-
-delete Array.prototype.push;
-GetIntrinsic('%Array.prototype.push%').call(arr, 4);
-assert.deepEqual(arr, [1, 2, 3, 4]);
-
-// missing features
-delete JSON.parse; // to simulate a real intrinsic that is missing in the environment
-assert.throws(() => GetIntrinsic('%JSON.parse%'));
-assert.equal(undefined, GetIntrinsic('%JSON.parse%', true));
-```
-
-## Tests
-Simply clone the repo, `npm install`, and run `npm test`
-
-## Security
-
-Please email [@ljharb](https://github.com/ljharb) or see https://tidelift.com/security if you have a potential security vulnerability to report.

-Determine if the JS environment has Symbol support. Supports spec, or shams.
-
-## Example
-
-```js
-var hasSymbols = require('has-symbols');
-
-hasSymbols() === true; // if the environment has native Symbol support. Not polyfillable, not forgeable.
-
-var hasSymbolsKinda = require('has-symbols/shams');
-hasSymbolsKinda() === true; // if the environment has a Symbol sham that mostly follows the spec.
-```
-
-## Supported Symbol shams
- - get-own-property-symbols [npm](https://www.npmjs.com/package/get-own-property-symbols) | [github](https://github.com/WebReflection/get-own-property-symbols)
- - core-js [npm](https://www.npmjs.com/package/core-js) | [github](https://github.com/zloirock/core-js)
-
-## Tests
-Simply clone the repo, `npm install`, and run `npm test`

-
-Create HTTP errors for Express, Koa, Connect, etc. with ease.
-
-## Install
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```console
-$ npm install http-errors
-```
-
-## Example
-
-```js
-var createError = require('http-errors')
-var express = require('express')
-var app = express()
-
-app.use(function (req, res, next) {
-  if (!req.user) return next(createError(401, 'Please login to view this page.'))
-  next()
-})
-```
-
-## API
-
-This is the current API, currently extracted from Koa and subject to change.
-
-### Error Properties
-
-- `expose` - can be used to signal if `message` should be sent to the client,
-  defaulting to `false` when `status` >= 500
-- `headers` - can be an object of header names to values to be sent to the
-  client, defaulting to `undefined`. When defined, the key names should all
-  be lower-cased
-- `message` - the traditional error message, which should be kept short and all
-  single line
-- `status` - the status code of the error, mirroring `statusCode` for general
-  compatibility
-- `statusCode` - the status code of the error, defaulting to `500`
-
-### createError([status], [message], [properties])
-
-Create a new error object with the given message `msg`.
-The error object inherits from `createError.HttpError`.
-
-```js
-var err = createError(404, 'This video does not exist!')
-```
-
-- `status: 500` - the status code as a number
-- `message` - the message of the error, defaulting to node's text for that status code.
-- `properties` - custom properties to attach to the object
-
-### createError([status], [error], [properties])
-
-Extend the given `error` object with `createError.HttpError`
-properties. This will not alter the inheritance of the given
-`error` object, and the modified `error` object is the
-return value.
-
-<!-- eslint-disable no-redeclare -->
-
-```js
-fs.readFile('foo.txt', function (err, buf) {
-  if (err) {
-    if (err.code === 'ENOENT') {
-      var httpError = createError(404, err, { expose: false })
-    } else {
-      var httpError = createError(500, err)
-    }
-  }
-})
-```
-
-- `status` - the status code as a number
-- `error` - the error object to extend
-- `properties` - custom properties to attach to the object
-
-### createError.isHttpError(val)
-
-Determine if the provided `val` is an `HttpError`. This will return `true`
-if the error inherits from the `HttpError` constructor of this module or
-matches the "duck type" for an error this module creates. All outputs from
-the `createError` factory will return `true` for this function, including
-if an non-`HttpError` was passed into the factory.
-
-### new createError\[code || name\](\[msg]\))
-
-Create a new error object with the given message `msg`.
-The error object inherits from `createError.HttpError`.
-
-```js
-var err = new createError.NotFound()
-```
-
-- `code` - the status code as a number
-- `name` - the name of the error as a "bumpy case", i.e. `NotFound` or `InternalServerError`.
-

-### 🐞 Bug fixes
-
-* Handle split surrogate pairs when encoding utf8 - by [@yosion-p](https://github.com/yosion-p) and [@ashtuchkin](https://github.com/ashtuchkin) in [#282](https://github.com/ashtuchkin/iconv-lite/pull/282):
-
-    Handle a case where streaming utf8 encoder (converting js strings -> buffers) encounters 
-    surrogate pairs split between chunks (last character of one chunk is high surrogate and first
-    character of the next chunk is a low surrogate).
-
-* Avoid false positives in encodingExists by using objects without a prototype - by [@bjohansebas](https://github.com/bjohansebas) in [#328](https://github.com/ashtuchkin/iconv-lite/pull/328)
-
-    The encodingExists method could return incorrect results if the lookup matched properties inherited
-    from the prototype of the object that stores the encodings, such as constructor and others. This change
-    replaces that object with one that has no prototype, ensuring that only explicitly defined valid encodings
-    in the library are considered. In addition, the fix is applied to the internal cache system to avoid the same
-    kind of false positives
-
-### 🚀 Improvements
-
-* Make explicit that decode() method supports Uint8Array input - by [@jardicc](https://github.com/jardicc) in [#271](https://github.com/ashtuchkin/iconv-lite/pull/271)
-* Remove compatibility check for StringDecoder.end method - by [@bjohansebas](https://github.com/bjohansebas) in [#331](https://github.com/ashtuchkin/iconv-lite/pull/331)
-
-## 0.6.3 / 2021-05-23
-  * Fix HKSCS encoding to prefer Big5 codes if both Big5 and HKSCS codes are possible (#264)
-
-
-## 0.6.2 / 2020-07-08
-  * Support Uint8Array-s decoding without conversion to Buffers, plus fix an edge case.
-
-
-## 0.6.1 / 2020-06-28
-  * Support Uint8Array-s directly when decoding (#246, by @gyzerok)
-  * Unify package.json version ranges to be strictly semver-compatible (#241)
-  * Fix minor issue in UTF-32 decoder's endianness detection code.
-
-
-## 0.6.0 / 2020-06-08
-  * Updated 'gb18030' encoding to :2005 edition (see https://github.com/whatwg/encoding/issues/22).
-  * Removed `iconv.extendNodeEncodings()` mechanism. It was deprecated 5 years ago and didn't work 
-    in recent Node versions.
-  * Reworked Streaming API behavior in browser environments to fix #204. Streaming API will be 
-    excluded by default in browser packs, saving ~100Kb bundle size, unless enabled explicitly using 
-    `iconv.enableStreamingAPI(require('stream'))`.
-  * Updates to development environment & tests:
-    * Added ./test/webpack private package to test complex new use cases that need custom environment. 
-      It's tested as a separate job in Travis CI.
-    * Updated generation code for the new EUC-KR index file format from Encoding Standard.
-    * Removed Buffer() constructor in tests (#197 by @gabrielschulhof).
-
-
-## 0.5.2 / 2020-06-08
-  * Added `iconv.getEncoder()` and `iconv.getDecoder()` methods to typescript definitions (#229).
-  * Fixed semver version to 6.1.2 to support Node 8.x (by @tanandara).
-  * Capped iconv version to 2.x as 3.x has dropped support for older Node versions.
-  * Switched from instanbul to c8 for code coverage.
-
-
-## 0.5.1 / 2020-01-18
-
-  * Added cp720 encoding (#221, by @kr-deps)
-  * (minor) Changed Changelog.md formatting to use h2. 
-
-
-## 0.5.0 / 2019-06-26
-
-  * Added UTF-32 encoding, both little-endian and big-endian variants (UTF-32LE, UTF32-BE). If endianness
-    is not provided for decoding, it's deduced automatically from the stream using a heuristic similar to
-    what we use in UTF-16. (great work in #216 by @kshetline)
-  * Several minor updates to README (#217 by @oldj, plus some more)
-  * Added Node versions 10 and 12 to Travis test harness.
-
-
-## 0.4.24 / 2018-08-22
-
-  * Added MIK encoding (#196, by @Ivan-Kalatchev)
-
-
-## 0.4.23 / 2018-05-07
-
-  * Fix deprecation warning in Node v10 due to the last usage of `new Buffer` (#185, by @felixbuenemann)
-  * Switched from NodeBuffer to Buffer in typings (#155 by @felixfbecker, #186 by @larssn)
-
-
-## 0.4.22 / 2018-05-05
-
-  * Use older semver style for dependencies to be compatible with Node version 0.10 (#182, by @dougwilson)
-  * Fix tests to accomodate fixes in Node v10 (#182, by @dougwilson)
-
-
-## 0.4.21 / 2018-04-06
-
-  * Fix encoding canonicalization (#156)
-  * Fix the paths in the "browser" field in package.json (#174 by @LMLB)
-  * Removed "contributors" section in package.json - see Git history instead.
-
-
-## 0.4.20 / 2018-04-06
-
-  * Updated `new Buffer()` usages with recommended replacements as it's being deprecated in Node v10 (#176, #178 by @ChALkeR)
-
-
-## 0.4.19 / 2017-09-09
-
-  * Fixed iso8859-1 codec regression in handling untranslatable characters (#162, caused by #147)
-  * Re-generated windows1255 codec, because it was updated in iconv project
-  * Fixed grammar in error message when iconv-lite is loaded with encoding other than utf8
-
-
-## 0.4.18 / 2017-06-13
-
-  * Fixed CESU-8 regression in Node v8.
-
-
-## 0.4.17 / 2017-04-22
-
- * Updated typescript definition file to support Angular 2 AoT mode (#153 by @larssn)
-
-
-## 0.4.16 / 2017-04-22
-
- * Added support for React Native (#150)
- * Changed iso8859-1 encoding to usine internal 'binary' encoding, as it's the same thing (#147 by @mscdex)
- * Fixed typo in Readme (#138 by @jiangzhuo)
- * Fixed build for Node v6.10+ by making correct version comparison
- * Added a warning if iconv-lite is loaded not as utf-8 (see #142)
-
-
-## 0.4.15 / 2016-11-21
-
- * Fixed typescript type definition (#137)
-
-
-## 0.4.14 / 2016-11-20
-
- * Preparation for v1.0
- * Added Node v6 and latest Node versions to Travis CI test rig
- * Deprecated Node v0.8 support
- * Typescript typings (@larssn)
- * Fix encoding of Euro character in GB 18030 (inspired by @lygstate)
- * Add ms prefix to dbcs windows encodings (@rokoroku)
-
-
-## 0.4.13 / 2015-10-01
-
- * Fix silly mistake in deprecation notice.
-
-
-## 0.4.12 / 2015-09-26
-
- * Node v4 support:
-   * Added CESU-8 decoding (#106)
-   * Added deprecation notice for `extendNodeEncodings`
-   * Added Travis tests for Node v4 and io.js latest (#105 by @Mithgol)
-
-
-## 0.4.11 / 2015-07-03
-
- * Added CESU-8 encoding.
-
-
-## 0.4.10 / 2015-05-26
-
- * Changed UTF-16 endianness heuristic to take into account any ASCII chars, not
-   just spaces. This should minimize the importance of "default" endianness.
-
-
-## 0.4.9 / 2015-05-24
-
- * Streamlined BOM handling: strip BOM by default, add BOM when encoding if 
-   addBOM: true. Added docs to Readme.
- * UTF16 now uses UTF16-LE by default.
- * Fixed minor issue with big5 encoding.
- * Added io.js testing on Travis; updated node-iconv version to test against.
-   Now we just skip testing SBCS encodings that node-iconv doesn't support.
- * (internal refactoring) Updated codec interface to use classes.
- * Use strict mode in all files.
-
-
-## 0.4.8 / 2015-04-14
- 
- * added alias UNICODE-1-1-UTF-7 for UTF-7 encoding (#94)
-
-
-## 0.4.7 / 2015-02-05
-
- * stop official support of Node.js v0.8. Should still work, but no guarantees.
-   reason: Packages needed for testing are hard to get on Travis CI.
- * work in environment where Object.prototype is monkey patched with enumerable 
-   props (#89).
-
-
-## 0.4.6 / 2015-01-12
- 
- * fix rare aliases of single-byte encodings (thanks @mscdex)
- * double the timeout for dbcs tests to make them less flaky on travis
-
-
-## 0.4.5 / 2014-11-20
-
- * fix windows-31j and x-sjis encoding support (@nleush)
- * minor fix: undefined variable reference when internal error happens
-
-
-## 0.4.4 / 2014-07-16
-
- * added encodings UTF-7 (RFC2152) and UTF-7-IMAP (RFC3501 Section 5.1.3)
- * fixed streaming base64 encoding
-
-
-## 0.4.3 / 2014-06-14
-
- * added encodings UTF-16BE and UTF-16 with BOM
-
-
-## 0.4.2 / 2014-06-12
-
- * don't throw exception if `extendNodeEncodings()` is called more than once
-
-
-## 0.4.1 / 2014-06-11
-
- * codepage 808 added
-
-
-## 0.4.0 / 2014-06-10
-
- * code is rewritten from scratch
- * all widespread encodings are supported
- * streaming interface added
- * browserify compatibility added
- * (optional) extend core primitive encodings to make usage even simpler

-## iconv-lite: Pure JS character encoding conversion
-
-[![NPM Version][npm-version-image]][npm-url]
-[![NPM Downloads][npm-downloads-image]][npm-downloads-url]
-[![License][license-image]][license-url]
-[![NPM Install Size][npm-install-size-image]][npm-install-size-url]
-
-* No need for native code compilation. Quick to install, works on Windows, Web, and in sandboxed environments.
-* Used in popular projects like [Express.js (body_parser)](https://github.com/expressjs/body-parser), 
-  [Grunt](http://gruntjs.com/), [Nodemailer](http://www.nodemailer.com/), [Yeoman](http://yeoman.io/) and others.
-* Faster than [node-iconv](https://github.com/bnoordhuis/node-iconv) (see below for performance comparison).
-* Intuitive encode/decode API, including Streaming support.
-* In-browser usage via [browserify](https://github.com/substack/node-browserify) or [webpack](https://webpack.js.org/) (~180kb gzip compressed with Buffer shim included).
-* Typescript [type definition file](https://github.com/ashtuchkin/iconv-lite/blob/master/lib/index.d.ts) included.
-* React Native is supported (need to install `stream` module to enable Streaming API).
-
-## Usage
-
-### Basic API
-
-```javascript
-var iconv = require('iconv-lite');
-
-// Convert from an encoded buffer to a js string.
-str = iconv.decode(Buffer.from([0x68, 0x65, 0x6c, 0x6c, 0x6f]), 'win1251');
-
-// Convert from a js string to an encoded buffer.
-buf = iconv.encode("Sample input string", 'win1251');
-
-// Check if encoding is supported
-iconv.encodingExists("us-ascii")
-```
-
-### Streaming API
-
-```javascript
-// Decode stream (from binary data stream to js strings)
-http.createServer(function(req, res) {
-    var converterStream = iconv.decodeStream('win1251');
-    req.pipe(converterStream);
-
-    converterStream.on('data', function(str) {
-        console.log(str); // Do something with decoded strings, chunk-by-chunk.
-    });
-});
-
-// Convert encoding streaming example
-fs.createReadStream('file-in-win1251.txt')
-    .pipe(iconv.decodeStream('win1251'))
-    .pipe(iconv.encodeStream('ucs2'))
-    .pipe(fs.createWriteStream('file-in-ucs2.txt'));
-
-// Sugar: all encode/decode streams have .collect(cb) method to accumulate data.
-http.createServer(function(req, res) {
-    req.pipe(iconv.decodeStream('win1251')).collect(function(err, body) {
-        assert(typeof body == 'string');
-        console.log(body); // full request body string
-    });
-});
-```
-
-## Supported encodings
-
- *  All node.js native encodings: utf8, ucs2 / utf16-le, ascii, binary, base64, hex.
- *  Additional unicode encodings: utf16, utf16-be, utf-7, utf-7-imap, utf32, utf32-le, and utf32-be.
- *  All widespread singlebyte encodings: Windows 125x family, ISO-8859 family, 
-    IBM/DOS codepages, Macintosh family, KOI8 family, all others supported by iconv library. 
-    Aliases like 'latin1', 'us-ascii' also supported.
- *  All widespread multibyte encodings: CP932, CP936, CP949, CP950, GB2312, GBK, GB18030, Big5, Shift_JIS, EUC-JP.
-
-See [all supported encodings on wiki](https://github.com/ashtuchkin/iconv-lite/wiki/Supported-Encodings).
-
-Most singlebyte encodings are generated automatically from [node-iconv](https://github.com/bnoordhuis/node-iconv). Thank you Ben Noordhuis and libiconv authors!
-
-Multibyte encodings are generated from [Unicode.org mappings](http://www.unicode.org/Public/MAPPINGS/) and [WHATWG Encoding Standard mappings](http://encoding.spec.whatwg.org/). Thank you, respective authors!
-
-## Encoding/decoding speed
-
-Comparison with node-iconv module (1000x256kb, on MacBook Pro, Core i5/2.6 GHz, Node v0.12.0). 
-Note: your results may vary, so please always check on your hardware.
-
-    operation             iconv@2.1.4   iconv-lite@0.4.7
-    ----------------------------------------------------------
-    encode('win1251')     ~96 Mb/s      ~320 Mb/s
-    decode('win1251')     ~95 Mb/s      ~246 Mb/s
-
-## BOM handling
-
- * Decoding: BOM is stripped by default, unless overridden by passing `stripBOM: false` in options
-   (f.ex. `iconv.decode(buf, enc, {stripBOM: false})`).
-   A callback might also be given as a `stripBOM` parameter - it'll be called if BOM character was actually found.
- * If you want to detect UTF-8 BOM when decoding other encodings, use [node-autodetect-decoder-stream](https://github.com/danielgindi/node-autodetect-decoder-stream) module.
- * Encoding: No BOM added, unless overridden by `addBOM: true` option.
-
-## UTF-16 Encodings
-
-This library supports UTF-16LE, UTF-16BE and UTF-16 encodings. First two are straightforward, but UTF-16 is trying to be
-smart about endianness in the following ways:
- * Decoding: uses BOM and 'spaces heuristic' to determine input endianness. Default is UTF-16LE, but can be 
-   overridden with `defaultEncoding: 'utf-16be'` option. Strips BOM unless `stripBOM: false`.
- * Encoding: uses UTF-16LE and writes BOM by default. Use `addBOM: false` to override.
-
-## UTF-32 Encodings
-
-This library supports UTF-32LE, UTF-32BE and UTF-32 encodings. Like the UTF-16 encoding above, UTF-32 defaults to UTF-32LE, but uses BOM and 'spaces heuristics' to determine input endianness. 
- * The default of UTF-32LE can be overridden with the `defaultEncoding: 'utf-32be'` option. Strips BOM unless `stripBOM: false`.
- * Encoding: uses UTF-32LE and writes BOM by default. Use `addBOM: false` to override. (`defaultEncoding: 'utf-32be'` can also be used here to change encoding.)
-
-## Other notes
-
-When decoding, be sure to supply a Buffer to decode() method, otherwise [bad things usually happen](https://github.com/ashtuchkin/iconv-lite/wiki/Use-Buffers-when-decoding).  
-Untranslatable characters are set to � or ?. No transliteration is currently supported.  
-Node versions 0.10.31 and 0.11.13 are buggy, don't use them (see [#65](https://github.com/ashtuchkin/iconv-lite/issues/65), [#77](https://github.com/ashtuchkin/iconv-lite/issues/77)).

-  // == Japanese/ShiftJIS ====================================================
-  // All japanese encodings are based on JIS X set of standards:
-  // JIS X 0201 - Single-byte encoding of ASCII + ¥ + Kana chars at 0xA1-0xDF.
-  // JIS X 0208 - Main set of 6879 characters, placed in 94x94 plane, to be encoded by 2 bytes.
-  //              Has several variations in 1978, 1983, 1990 and 1997.
-  // JIS X 0212 - Supplementary plane of 6067 chars in 94x94 plane. 1990. Effectively dead.
-  // JIS X 0213 - Extension and modern replacement of 0208 and 0212. Total chars: 11233.
-  //              2 planes, first is superset of 0208, second - revised 0212.
-  //              Introduced in 2000, revised 2004. Some characters are in Unicode Plane 2 (0x2xxxx)
-
-  // Byte encodings are:
-  //  * Shift_JIS: Compatible with 0201, uses not defined chars in top half as lead bytes for double-byte
-  //               encoding of 0208. Lead byte ranges: 0x81-0x9F, 0xE0-0xEF; Trail byte ranges: 0x40-0x7E, 0x80-0x9E, 0x9F-0xFC.
-  //               Windows CP932 is a superset of Shift_JIS. Some companies added more chars, notably KDDI.
-  //  * EUC-JP:    Up to 3 bytes per character. Used mostly on *nixes.
-  //               0x00-0x7F       - lower part of 0201
-  //               0x8E, 0xA1-0xDF - upper part of 0201
-  //               (0xA1-0xFE)x2   - 0208 plane (94x94).
-  //               0x8F, (0xA1-0xFE)x2 - 0212 plane (94x94).
-  //  * JIS X 208: 7-bit, direct encoding of 0208. Byte ranges: 0x21-0x7E (94 values). Uncommon.
-  //               Used as-is in ISO2022 family.
-  //  * ISO2022-JP: Stateful encoding, with escape sequences to switch between ASCII,
-  //                0201-1976 Roman, 0208-1978, 0208-1983.
-  //  * ISO2022-JP-1: Adds esc seq for 0212-1990.
-  //  * ISO2022-JP-2: Adds esc seq for GB2313-1980, KSX1001-1992, ISO8859-1, ISO8859-7.
-  //  * ISO2022-JP-3: Adds esc seq for 0201-1976 Kana set, 0213-2000 Planes 1, 2.
-  //  * ISO2022-JP-2004: Adds 0213-2004 Plane 1.
-  //
-  // After JIS X 0213 appeared, Shift_JIS-2004, EUC-JISX0213 and ISO2022-JP-2004 followed, with just changing the planes.

-Browser-friendly inheritance fully compatible with standard node.js
-[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
-
-This package exports standard `inherits` from node.js `util` module in
-node environment, but also provides alternative browser-friendly
-implementation through [browser
-field](https://gist.github.com/shtylman/4339901). Alternative
-implementation is a literal copy of standard one located in standalone
-module to avoid requiring of `util`. It also has a shim for old
-browsers with no `Object.create` support.
-
-While keeping you sure you are using standard `inherits`
-implementation in node.js environment, it allows bundlers such as
-[browserify](https://github.com/substack/node-browserify) to not
-include full `util` package to your client code if all you need is
-just `inherits` function. It worth, because browser shim for `util`
-package is large and `inherits` is often the single function you need
-from it.
-
-It's recommended to use this package instead of
-`require('util').inherits` for any code that has chances to be used
-not only in node.js but in browser too.
-
-## usage
-
-```js
-var inherits = require('inherits');
-// then use exactly as the standard one
-```
-
-## note on version ~1.0
-
-Version ~1.0 had completely different motivation and is not compatible
-neither with 2.0 nor with standard node.js `inherits`.
-
-If you are using version ~1.0 and planning to switch to ~2.0, be
-careful:
-
-* new version uses `super_` instead of `super` for referencing
-  superclass
-* new version overwrites current prototype while old one preserves any
-  existing fields on it

-# ipaddr.js — an IPv6 and IPv4 address manipulation library [![Build Status](https://travis-ci.org/whitequark/ipaddr.js.svg)](https://travis-ci.org/whitequark/ipaddr.js)
-
-ipaddr.js is a small (1.9K minified and gzipped) library for manipulating
-IP addresses in JavaScript environments. It runs on both CommonJS runtimes
-(e.g. [nodejs]) and in a web browser.
-
-ipaddr.js allows you to verify and parse string representation of an IP
-address, match it against a CIDR range or range list, determine if it falls
-into some reserved ranges (examples include loopback and private ranges),
-and convert between IPv4 and IPv4-mapped IPv6 addresses.
-
-[nodejs]: http://nodejs.org
-
-## Installation
-
-`npm install ipaddr.js`
-
-or
-
-`bower install ipaddr.js`
-
-## API
-
-ipaddr.js defines one object in the global scope: `ipaddr`. In CommonJS,
-it is exported from the module:
-
-```js
-var ipaddr = require('ipaddr.js');
-```
-
-The API consists of several global methods and two classes: ipaddr.IPv6 and ipaddr.IPv4.
-
-### Global methods
-
-There are three global methods defined: `ipaddr.isValid`, `ipaddr.parse` and
-`ipaddr.process`. All of them receive a string as a single parameter.
-
-The `ipaddr.isValid` method returns `true` if the address is a valid IPv4 or
-IPv6 address, and `false` otherwise. It does not throw any exceptions.
-
-The `ipaddr.parse` method returns an object representing the IP address,
-or throws an `Error` if the passed string is not a valid representation of an
-IP address.
-
-The `ipaddr.process` method works just like the `ipaddr.parse` one, but it
-automatically converts IPv4-mapped IPv6 addresses to their IPv4 counterparts
-before returning. It is useful when you have a Node.js instance listening
-on an IPv6 socket, and the `net.ivp6.bindv6only` sysctl parameter (or its
-equivalent on non-Linux OS) is set to 0. In this case, you can accept IPv4
-connections on your IPv6-only socket, but the remote address will be mangled.
-Use `ipaddr.process` method to automatically demangle it.
-
-### Object representation
-
-Parsing methods return an object which descends from `ipaddr.IPv6` or
-`ipaddr.IPv4`. These objects share some properties, but most of them differ.
-
-#### Shared properties
-
-One can determine the type of address by calling `addr.kind()`. It will return
-either `"ipv6"` or `"ipv4"`.
-
-An address can be converted back to its string representation with `addr.toString()`.
-Note that this method:
- * does not return the original string used to create the object (in fact, there is
-   no way of getting that string)
- * returns a compact representation (when it is applicable)
-
-A `match(range, bits)` method can be used to check if the address falls into a
-certain CIDR range.
-Note that an address can be (obviously) matched only against an address of the same type.
-
-For example:
-
-```js
-var addr = ipaddr.parse("2001:db8:1234::1");
-var range = ipaddr.parse("2001:db8::");
-
-addr.match(range, 32); // => true
-```
-
-Alternatively, `match` can also be called as `match([range, bits])`. In this way,
-it can be used together with the `parseCIDR(string)` method, which parses an IP
-address together with a CIDR range.
-
-For example:
-
-```js
-var addr = ipaddr.parse("2001:db8:1234::1");
-
-addr.match(ipaddr.parseCIDR("2001:db8::/32")); // => true
-```
-
-A `range()` method returns one of predefined names for several special ranges defined
-by IP protocols. The exact names (and their respective CIDR ranges) can be looked up
-in the source: [IPv6 ranges] and [IPv4 ranges]. Some common ones include `"unicast"`
-(the default one) and `"reserved"`.
-
-You can match against your own range list by using
-`ipaddr.subnetMatch(address, rangeList, defaultName)` method. It can work with a mix of IPv6 or IPv4 addresses, and accepts a name-to-subnet map as the range list. For example:
-
-```js
-var rangeList = {
-  documentationOnly: [ ipaddr.parse('2001:db8::'), 32 ],
-  tunnelProviders: [
-    [ ipaddr.parse('2001:470::'), 32 ], // he.net
-    [ ipaddr.parse('2001:5c0::'), 32 ]  // freenet6
-  ]
-};
-ipaddr.subnetMatch(ipaddr.parse('2001:470:8:66::1'), rangeList, 'unknown'); // => "tunnelProviders"
-```
-
-The addresses can be converted to their byte representation with `toByteArray()`.
-(Actually, JavaScript mostly does not know about byte buffers. They are emulated with
-arrays of numbers, each in range of 0..255.)
-
-```js
-var bytes = ipaddr.parse('2a00:1450:8007::68').toByteArray(); // ipv6.google.com
-bytes // => [42, 0x00, 0x14, 0x50, 0x80, 0x07, 0x00, <zeroes...>, 0x00, 0x68 ]
-```
-
-The `ipaddr.IPv4` and `ipaddr.IPv6` objects have some methods defined, too. All of them
-have the same interface for both protocols, and are similar to global methods.
-
-`ipaddr.IPvX.isValid(string)` can be used to check if the string is a valid address
-for particular protocol, and `ipaddr.IPvX.parse(string)` is the error-throwing parser.
-
-`ipaddr.IPvX.isValid(string)` uses the same format for parsing as the POSIX `inet_ntoa` function, which accepts unusual formats like `0xc0.168.1.1` or `0x10000000`. The function `ipaddr.IPv4.isValidFourPartDecimal(string)` validates the IPv4 address and also ensures that it is written in four-part decimal format.

-[IPv4 ranges]: https://github.com/whitequark/ipaddr.js/blob/master/src/ipaddr.coffee#L71
-
-#### IPv6 properties
-
-Sometimes you will want to convert IPv6 not to a compact string representation (with
-the `::` substitution); the `toNormalizedString()` method will return an address where
-all zeroes are explicit.
-
-For example:
-
-```js
-var addr = ipaddr.parse("2001:0db8::0001");
-addr.toString(); // => "2001:db8::1"
-addr.toNormalizedString(); // => "2001:db8:0:0:0:0:0:1"
-```
-
-The `isIPv4MappedAddress()` method will return `true` if this address is an IPv4-mapped
-one, and `toIPv4Address()` will return an IPv4 object address.
-
-To access the underlying binary representation of the address, use `addr.parts`.
-
-```js
-var addr = ipaddr.parse("2001:db8:10::1234:DEAD");
-addr.parts // => [0x2001, 0xdb8, 0x10, 0, 0, 0, 0x1234, 0xdead]
-```
-
-A IPv6 zone index can be accessed via `addr.zoneId`:
-
-```js
-var addr = ipaddr.parse("2001:db8::%eth0");
-addr.zoneId // => 'eth0'
-```
-
-#### IPv4 properties
-
-`toIPv4MappedAddress()` will return a corresponding IPv4-mapped IPv6 address.
-
-To access the underlying representation of the address, use `addr.octets`.
-
-```js
-var addr = ipaddr.parse("192.168.1.1");
-addr.octets // => [192, 168, 1, 1]
-```
-
-`prefixLengthFromSubnetMask()` will return a CIDR prefix length for a valid IPv4 netmask or
-null if the netmask is not valid.
-
-```js
-ipaddr.IPv4.parse('255.255.255.240').prefixLengthFromSubnetMask() == 28
-ipaddr.IPv4.parse('255.192.164.0').prefixLengthFromSubnetMask()  == null
-```
-
-`subnetMaskFromPrefixLength()` will return an IPv4 netmask for a valid CIDR prefix length.
-
-```js
-ipaddr.IPv4.subnetMaskFromPrefixLength(24) == "255.255.255.0"
-ipaddr.IPv4.subnetMaskFromPrefixLength(29) == "255.255.255.248"
-```
-
-`broadcastAddressFromCIDR()` will return the broadcast address for a given IPv4 interface and netmask in CIDR notation.
-```js
-ipaddr.IPv4.broadcastAddressFromCIDR("172.0.0.1/24") == "172.0.0.255"
-```
-`networkAddressFromCIDR()` will return the network address for a given IPv4 interface and netmask in CIDR notation.
-```js
-ipaddr.IPv4.networkAddressFromCIDR("172.0.0.1/24") == "172.0.0.0"
-```
-
-#### Conversion
-
-IPv4 and IPv6 can be converted bidirectionally to and from network byte order (MSB) byte arrays.
-
-The `fromByteArray()` method will take an array and create an appropriate IPv4 or IPv6 object
-if the input satisfies the requirements. For IPv4 it has to be an array of four 8-bit values,
-while for IPv6 it has to be an array of sixteen 8-bit values.
-
-For example:
-```js
-var addr = ipaddr.fromByteArray([0x7f, 0, 0, 1]);
-addr.toString(); // => "127.0.0.1"
-```
-
-or
-
-```js
-var addr = ipaddr.fromByteArray([0x20, 1, 0xd, 0xb8, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1])
-addr.toString(); // => "2001:db8::1"
-```
-
-Both objects also offer a `toByteArray()` method, which returns an array in network byte order (MSB).
-
-For example:
-```js
-var addr = ipaddr.parse("127.0.0.1");
-addr.toByteArray(); // => [0x7f, 0, 0, 1]
-```
-
-or
-
-```js
-var addr = ipaddr.parse("2001:db8::1");
-addr.toByteArray(); // => [0x20, 1, 0xd, 0xb8, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1]
-```

-  * Remove parameter handling, which is outside RFC 6838 scope
-  * Remove `parse(req)` and `parse(res)` signatures
-  * perf: enable strict mode
-  * perf: use a class for object creation
-
-0.3.0 / 2014-09-07
-==================
-
-  * Support Node.js 0.6
-  * Throw error when parameter format invalid on parse
-
-0.2.0 / 2014-06-18
-==================
-
-  * Add `typer.format()` to format media types
-
-0.1.0 / 2014-06-17
-==================
-
-  * Accept `req` as argument to `parse`
-  * Accept `res` as argument to `parse`

-Simple RFC 6838 media type parser.
-
-This module will parse a given media type into it's component parts, like type,
-subtype, and suffix. A formatter is also provided to put them back together and
-the two can be combined to normalize media types into a canonical form.
-
-If you are looking to parse the string that represents a media type and it's
-parameters in HTTP (for example, the `Content-Type` header), use the
-[content-type module](https://www.npmjs.com/package/content-type).
-
-## Installation
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install media-typer
-```
-
-## API
-
-<!-- eslint-disable no-unused-vars -->
-
-```js
-var typer = require('media-typer')
-```
-
-### typer.parse(string)
-
-<!-- eslint-disable no-undef, no-unused-vars -->
-
-```js
-var obj = typer.parse('image/svg+xml')
-```
-
-Parse a media type string. This will return an object with the following
-properties (examples are shown for the string `'image/svg+xml; charset=utf-8'`):
-
- - `type`: The type of the media type (always lower case). Example: `'image'`
-
- - `subtype`: The subtype of the media type (always lower case). Example: `'svg'`
-
- - `suffix`: The suffix of the media type (always lower case). Example: `'xml'`
-
-If the given type string is invalid, then a `TypeError` is thrown.
-
-### typer.format(obj)
-
-<!-- eslint-disable no-undef, no-unused-vars -->
-
-```js
-var obj = typer.format({ type: 'image', subtype: 'svg', suffix: 'xml' })
-```
-
-Format an object into a media type string. This will return a string of the
-mime type for the given object. For the properties of the object, see the
-documentation for `typer.parse(string)`.
-
-If any of the given object values are invalid, then a `TypeError` is thrown.
-
-### typer.test(string)
-
-<!-- eslint-disable no-undef, no-unused-vars -->
-
-```js
-var valid = typer.test('image/svg+xml')
-```
-
-Validate a media type string. This will return `true` is the string is a well-
-formatted media type, or `false` otherwise.

-# mime-db
-
-[![NPM Version][npm-version-image]][npm-url]
-[![NPM Downloads][npm-downloads-image]][npm-url]
-[![Node.js Version][node-image]][node-url]
-[![Build Status][ci-image]][ci-url]
-[![Coverage Status][coveralls-image]][coveralls-url]
-
-This is a large database of mime types and information about them.
-It consists of a single, public JSON file and does not include any logic,
-allowing it to remain as un-opinionated as possible with an API.
-It aggregates data from the following sources:
-
-- https://www.iana.org/assignments/media-types/media-types.xhtml
-- https://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types
-- https://hg.nginx.org/nginx/raw-file/default/conf/mime.types
-
-## Installation
-
-```bash
-npm install mime-db
-```
-
-### Database Download
-
-If you intend to use this in a web browser, you can conveniently access the JSON file via [jsDelivr](https://www.jsdelivr.com/), a popular CDN (Content Delivery Network). To ensure stability and compatibility, it is advisable to specify [a release tag](https://github.com/jshttp/mime-db/tags) instead of using the 'master' branch. This is because the JSON file's format might change in future updates, and relying on a specific release tag will prevent potential issues arising from these changes.
-
-```
-https://cdn.jsdelivr.net/gh/jshttp/mime-db@master/db.json
-```
-
-## Usage
-
-```js
-var db = require('mime-db')
-
-// grab data on .js files
-var data = db['application/javascript']
-```
-
-## Data Structure
-
-The JSON file is a map lookup for lowercased mime types.
-Each mime type has the following properties:
-
-- `.source` - where the mime type is defined.
-    If not set, it's probably a custom media type.
-    - `apache` - [Apache common media types](https://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types)
-    - `iana` - [IANA-defined media types](https://www.iana.org/assignments/media-types/media-types.xhtml)
-    - `nginx` - [nginx media types](https://hg.nginx.org/nginx/raw-file/default/conf/mime.types)
-- `.extensions[]` - known extensions associated with this mime type.
-- `.compressible` - whether a file of this type can be gzipped.
-- `.charset` - the default charset associated with this type, if any.
-
-If unknown, every property could be `undefined`.
-
-## Note on MIME Type Data and Semver
-
-This package considers the programmatic api as the semver compatibility. This means the MIME type resolution is *not* considered
-in the semver bumps. This means that if you want to pin your `mime-db` data you will need to do it in your application. While
-this expectation was not set in docs until now, it is how the pacakge operated, so we do not feel this is a breaking change.
-
-## Contributing
-
-The primary way to contribute to this database is by updating the data in
-one of the upstream sources. The database is updated from the upstreams
-periodically and will pull in any changes.
-
-### Registering Media Types
-
-The best way to get new media types included in this library is to register
-them with the IANA. The community registration procedure is outlined in
-[RFC 6838 section 5](https://tools.ietf.org/html/rfc6838#section-5). Types
-registered with the IANA are automatically pulled into this library.
-
-### Direct Inclusion
-
-If that is not possible / feasible, they can be added directly here as a
-"custom" type. To do this, it is required to have a primary source that
-definitively lists the media type. If an extension is going to be listed as
-associated with this media type, the source must definitively link the
-media type and extension as well.
-
-To edit the database, only make PRs against `src/custom-types.json` or
-`src/custom-suffix.json`.
-
-The `src/custom-types.json` file is a JSON object with the MIME type as the
-keys and the values being an object with the following keys:
-
-- `compressible` - leave out if you don't know, otherwise `true`/`false` to
-  indicate whether the data represented by the type is typically compressible.
-- `extensions` - include an array of file extensions that are associated with
-  the type.
-- `notes` - human-readable notes about the type, typically what the type is.
-- `sources` - include an array of URLs of where the MIME type and the associated
-  extensions are sourced from. This needs to be a [primary source](https://en.wikipedia.org/wiki/Primary_source);
-  links to type aggregating sites and Wikipedia are _not acceptable_.
-
-To update the build, run `npm run build`.

-
-The ultimate javascript content-type utility.
-
-Similar to [the `mime@1.x` module](https://www.npmjs.com/package/mime), except:
-
-- __No fallbacks.__ Instead of naively returning the first available type,
-  `mime-types` simply returns `false`, so do
-  `var type = mime.lookup('unrecognized') || 'application/octet-stream'`.
-- No `new Mime()` business, so you could do `var lookup = require('mime-types').lookup`.
-- No `.define()` functionality
-- Bug fixes for `.lookup(path)`
-
-Otherwise, the API is compatible with `mime` 1.x.
-
-## Install
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install mime-types
-```
-
-## Note on MIME Type Data and Semver
-
-This package considers the programmatic api as the semver compatibility. Additionally, the package which provides the MIME data
-for this package (`mime-db`) *also* considers it's programmatic api as the semver contract. This means the MIME type resolution is *not* considered
-in the semver bumps.
-
-In the past the version of `mime-db` was pinned to give two decision points when adopting MIME data changes. This is no longer true. We still update the
-`mime-db` package here as a `minor` release when necessary, but will use a `^` range going forward. This means that if you want to pin your `mime-db` data
-you will need to do it in your application. While this expectation was not set in docs until now, it is how the pacakge operated, so we do not feel this is
-a breaking change.
-
-If you wish to pin your `mime-db` version you can do that with overrides via your package manager of choice. See their documentation for how to correctly configure that.
-
-## Adding Types
-
-All mime types are based on [mime-db](https://www.npmjs.com/package/mime-db),
-so open a PR there if you'd like to add mime types.
-
-## API
-
-```js
-var mime = require('mime-types')
-```
-
-All functions return `false` if input is invalid or not found.
-
-### mime.lookup(path)
-
-Lookup the content-type associated with a file.
-
-```js
-mime.lookup('json') // 'application/json'
-mime.lookup('.md') // 'text/markdown'
-mime.lookup('file.html') // 'text/html'
-mime.lookup('folder/file.js') // 'application/javascript'
-mime.lookup('folder/.htaccess') // false
-
-mime.lookup('cats') // false
-```
-
-### mime.contentType(type)
-
-Create a full content-type header given a content-type or extension.
-When given an extension, `mime.lookup` is used to get the matching
-content-type, otherwise the given content-type is used. Then if the
-content-type does not already have a `charset` parameter, `mime.charset`
-is used to get the default charset and add to the returned content-type.
-
-```js
-mime.contentType('markdown') // 'text/x-markdown; charset=utf-8'
-mime.contentType('file.json') // 'application/json; charset=utf-8'
-mime.contentType('text/html') // 'text/html; charset=utf-8'
-mime.contentType('text/html; charset=iso-8859-1') // 'text/html; charset=iso-8859-1'
-
-// from a full path
-mime.contentType(path.extname('/path/to/file.json')) // 'application/json; charset=utf-8'
-```
-
-### mime.extension(type)
-
-Get the default extension for a content-type.
-
-```js
-mime.extension('application/octet-stream') // 'bin'
-```
-
-### mime.charset(type)
-
-Lookup the implied default charset of a content-type.
-
-```js
-mime.charset('text/markdown') // 'UTF-8'
-```
-
-### var type = mime.types[extension]
-
-A map of content-types by extension.
-
-### [extensions...] = mime.extensions[type]
-
-A map of extensions by content-type.

-# ms
-
-![CI](https://github.com/vercel/ms/workflows/CI/badge.svg)
-
-Use this package to easily convert various time formats to milliseconds.
-
-## Examples
-
-```js
-ms('2 days')  // 172800000
-ms('1d')      // 86400000
-ms('10h')     // 36000000
-ms('2.5 hrs') // 9000000
-ms('2h')      // 7200000
-ms('1m')      // 60000
-ms('5s')      // 5000
-ms('1y')      // 31557600000
-ms('100')     // 100
-ms('-3 days') // -259200000
-ms('-1h')     // -3600000
-ms('-200')    // -200
-```
-
-### Convert from Milliseconds
-
-```js
-ms(60000)             // "1m"
-ms(2 * 60000)         // "2m"
-ms(-3 * 60000)        // "-3m"
-ms(ms('10 hours'))    // "10h"
-```
-
-### Time Format Written-Out
-
-```js
-ms(60000, { long: true })             // "1 minute"
-ms(2 * 60000, { long: true })         // "2 minutes"
-ms(-3 * 60000, { long: true })        // "-3 minutes"
-ms(ms('10 hours'), { long: true })    // "10 hours"
-```
-
-## Features
-
-- Works both in [Node.js](https://nodejs.org) and in the browser
-- If a number is supplied to `ms`, a string with a unit is returned
-- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`)
-- If you pass a string with a number and a valid unit, the number of equivalent milliseconds is returned
-
-## Related Packages
-
-- [ms.macro](https://github.com/knpwrs/ms.macro) - Run `ms` as a macro at build-time.
-
-## Caught a Bug?
-
-1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
-2. Link the package to the global module directory: `npm link`
-3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, Node.js will now use your clone of ms!
-
-As always, you can run the tests using: `npm test`

-# object-assign [![Build Status](https://travis-ci.org/sindresorhus/object-assign.svg?branch=master)](https://travis-ci.org/sindresorhus/object-assign)
-
-> ES2015 [`Object.assign()`](http://www.2ality.com/2014/01/object-assign.html) [ponyfill](https://ponyfill.com)
-
-
-## Use the built-in
-
-Node.js 4 and up, as well as every evergreen browser (Chrome, Edge, Firefox, Opera, Safari),
-support `Object.assign()` :tada:. If you target only those environments, then by all
-means, use `Object.assign()` instead of this package.
-
-
-## Install
-
-```
-$ npm install --save object-assign
-```
-
-
-## Usage
-
-```js
-const objectAssign = require('object-assign');
-
-objectAssign({foo: 0}, {bar: 1});
-//=> {foo: 0, bar: 1}
-
-// multiple sources
-objectAssign({foo: 0}, {bar: 1}, {baz: 2});
-//=> {foo: 0, bar: 1, baz: 2}
-
-// overwrites equal keys
-objectAssign({foo: 0}, {foo: 1}, {foo: 2});
-//=> {foo: 2}
-
-// ignores null and undefined sources
-objectAssign({foo: 0}, null, {bar: 1}, undefined);
-//=> {foo: 0, bar: 1}
-```
-
-
-## API
-
-### objectAssign(target, [source, ...])
-
-Assigns enumerable own properties of `source` objects to the `target` object and returns the `target` object. Additional `source` objects will overwrite previous ones.

-# example
-
-## circular
-
-``` js
-var inspect = require('object-inspect');
-var obj = { a: 1, b: [3,4] };
-obj.c = obj;
-console.log(inspect(obj));
-```
-
-## dom element
-
-``` js
-var inspect = require('object-inspect');
-
-var d = document.createElement('div');
-d.setAttribute('id', 'beep');
-d.innerHTML = '<b>wooo</b><i>iiiii</i>';
-
-console.log(inspect([ d, { a: 3, b : 4, c: [5,6,[7,[8,[9]]]] } ]));
-```
-
-output:
-
-```
-[ <div id="beep">...</div>, { a: 3, b: 4, c: [ 5, 6, [ 7, [ 8, [ ... ] ] ] ] } ]
-```
-
-# methods
-
-``` js
-var inspect = require('object-inspect')
-```
-
-## var s = inspect(obj, opts={})
-
-Return a string `s` with the string representation of `obj` up to a depth of `opts.depth`.
-
-Additional options:
-  - `quoteStyle`: must be "single" or "double", if present. Default `'single'` for strings, `'double'` for HTML elements.
-  - `maxStringLength`: must be `0`, a positive integer, `Infinity`, or `null`, if present. Default `Infinity`.
-  - `customInspect`: When `true`, a custom inspect method function will be invoked (either undere the `util.inspect.custom` symbol, or the `inspect` property). When the string `'symbol'`, only the symbol method will be invoked. Default `true`.
-  - `indent`: must be "\t", `null`, or a positive integer. Default `null`.
-  - `numericSeparator`: must be a boolean, if present. Default `false`. If `true`, all numbers will be printed with numeric separators (eg, `1234.5678` will be printed as `'1_234.567_8'`)

-
-Execute a callback when a HTTP request closes, finishes, or errors.
-
-## Install
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install on-finished
-```
-
-## API
-
-```js
-var onFinished = require('on-finished')
-```
-
-### onFinished(res, listener)
-
-Attach a listener to listen for the response to finish. The listener will
-be invoked only once when the response finished. If the response finished
-to an error, the first argument will contain the error. If the response
-has already finished, the listener will be invoked.
-
-Listening to the end of a response would be used to close things associated
-with the response, like open files.
-
-Listener is invoked as `listener(err, res)`.
-
-<!-- eslint-disable handle-callback-err -->
-
-```js
-onFinished(res, function (err, res) {
-  // clean up open fds, etc.
-  // err contains the error if request error'd
-})
-```
-
-### onFinished(req, listener)
-
-Attach a listener to listen for the request to finish. The listener will
-be invoked only once when the request finished. If the request finished
-to an error, the first argument will contain the error. If the request
-has already finished, the listener will be invoked.
-
-Listening to the end of a request would be used to know when to continue
-after reading the data.
-
-Listener is invoked as `listener(err, req)`.
-
-<!-- eslint-disable handle-callback-err -->
-
-```js
-var data = ''
-
-req.setEncoding('utf8')
-req.on('data', function (str) {
-  data += str
-})
-
-onFinished(req, function (err, req) {
-  // data is read unless there is err
-})
-```
-
-### onFinished.isFinished(res)
-
-Determine if `res` is already finished. This would be useful to check and
-not even start certain operations if the response has already finished.
-
-### onFinished.isFinished(req)
-
-Determine if `req` is already finished. This would be useful to check and
-not even start certain operations if the request has already finished.
-
-## Special Node.js requests
-
-### HTTP CONNECT method
-
-The meaning of the `CONNECT` method from RFC 7231, section 4.3.6:
-
-> The CONNECT method requests that the recipient establish a tunnel to
-> the destination origin server identified by the request-target and,
-> if successful, thereafter restrict its behavior to blind forwarding
-> of packets, in both directions, until the tunnel is closed.  Tunnels
-> are commonly used to create an end-to-end virtual connection, through
-> one or more proxies, which can then be secured using TLS (Transport
-> Layer Security, [RFC5246]).
-
-In Node.js, these request objects come from the `'connect'` event on
-the HTTP server.
-
-When this module is used on a HTTP `CONNECT` request, the request is
-considered "finished" immediately, **due to limitations in the Node.js
-interface**. This means if the `CONNECT` request contains a request entity,
-the request will be considered "finished" even before it has been read.
-
-There is no such thing as a response object to a `CONNECT` request in
-Node.js, so there is no support for one.
-
-### HTTP Upgrade request
-
-The meaning of the `Upgrade` header from RFC 7230, section 6.1:
-
-> The "Upgrade" header field is intended to provide a simple mechanism
-> for transitioning from HTTP/1.1 to some other protocol on the same
-> connection.
-
-In Node.js, these request objects come from the `'upgrade'` event on
-the HTTP server.
-
-When this module is used on a HTTP request with an `Upgrade` header, the
-request is considered "finished" immediately, **due to limitations in the
-Node.js interface**. This means if the `Upgrade` request contains a request
-entity, the request will be considered "finished" even before it has been
-read.
-
-There is no such thing as a response object to a `Upgrade` request in
-Node.js, so there is no support for one.
-
-## Example
-
-The following code ensures that file descriptors are always closed
-once the response finishes.
-
-```js
-var destroy = require('destroy')
-var fs = require('fs')
-var http = require('http')
-var onFinished = require('on-finished')
-
-http.createServer(function onRequest (req, res) {
-  var stream = fs.createReadStream('package.json')
-  stream.pipe(res)
-  onFinished(res, function () {
-    destroy(stream)
-  })
-})
-```

-# once
-
-Only call a function once.
-
-## usage
-
-```javascript
-var once = require('once')
-
-function load (file, cb) {
-  cb = once(cb)
-  loader.load('file')
-  loader.once('load', cb)
-  loader.once('error', cb)
-}
-```
-
-Or add to the Function.prototype in a responsible way:
-
-```javascript
-// only has to be done once
-require('once').proto()
-
-function load (file, cb) {
-  cb = cb.once()
-  loader.load('file')
-  loader.once('load', cb)
-  loader.once('error', cb)
-}
-```
-
-Ironically, the prototype feature makes this module twice as
-complicated as necessary.
-
-To check whether you function has been called, use `fn.called`. Once the
-function is called for the first time the return value of the original
-function is saved in `fn.value` and subsequent calls will continue to
-return this value.
-
-```javascript
-var once = require('once')
-
-function load (cb) {
-  cb = once(cb)
-  var stream = createStream()
-  stream.once('data', cb)
-  stream.once('end', function () {
-    if (!cb.called) cb(new Error('not found'))
-  })
-}
-```
-
-## `once.strict(func)`
-
-Throw an error if the function is called twice.
-
-Some functions are expected to be called only once. Using `once` for them would
-potentially hide logical errors.
-
-In the example below, the `greet` function has to call the callback only once:
-
-```javascript
-function greet (name, cb) {
-  // return is missing from the if statement
-  // when no name is passed, the callback is called twice
-  if (!name) cb('Hello anonymous')
-  cb('Hello ' + name)
-}
-
-function log (msg) {
-  console.log(msg)
-}
-
-// this will print 'Hello anonymous' but the logical error will be missed
-greet(null, once(msg))
-
-// once.strict will print 'Hello anonymous' and throw an error when the callback will be called the second time
-greet(null, once.strict(msg))
-```

-Parse a URL with memoization.
-
-## Install
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install parseurl
-```
-
-## API
-
-```js
-var parseurl = require('parseurl')
-```
-
-### parseurl(req)
-
-Parse the URL of the given request object (looks at the `req.url` property)
-and return the result. The result is the same as `url.parse` in Node.js core.
-Calling this function multiple times on the same `req` where `req.url` does
-not change will return a cached parsed object, rather than parsing again.
-
-### parseurl.original(req)
-
-Parse the original URL of the given request object and return the result.
-This works by trying to parse `req.originalUrl` if it is a string, otherwise
-parses `req.url`. The result is the same as `url.parse` in Node.js core.
-Calling this function multiple times on the same `req` where `req.originalUrl`
-does not change will return a cached parsed object, rather than parsing again.

-# Path-to-RegExp
-
-> Turn a path string such as `/user/:name` into a regular expression.

-[![NPM downloads][downloads-image]][downloads-url]
-[![Build status][build-image]][build-url]

-
-## Installation
-
-```
-npm install path-to-regexp --save
-```
-
-## Usage
-
-```js
-const {
-  match,
-  pathToRegexp,
-  compile,
-  parse,
-  stringify,
-} = require("path-to-regexp");
-```
-
-### Parameters
-
-Parameters match arbitrary strings in a path by matching up to the end of the segment, or up to any proceeding tokens. They are defined by prefixing a colon to the parameter name (`:foo`). Parameter names can use any valid JavaScript identifier, or be double quoted to use other characters (`:"param-name"`).
-
-```js
-const fn = match("/:foo/:bar");
-
-fn("/test/route");
-//=> { path: '/test/route', params: { foo: 'test', bar: 'route' } }
-```
-
-### Wildcard
-
-Wildcard parameters match one or more characters across multiple segments. They are defined the same way as regular parameters, but are prefixed with an asterisk (`*foo`).
-
-```js
-const fn = match("/*splat");
-
-fn("/bar/baz");
-//=> { path: '/bar/baz', params: { splat: [ 'bar', 'baz' ] } }
-```
-
-### Optional
-
-Braces can be used to define parts of the path that are optional.
-
-```js
-const fn = match("/users{/:id}/delete");
-
-fn("/users/delete");
-//=> { path: '/users/delete', params: {} }
-
-fn("/users/123/delete");
-//=> { path: '/users/123/delete', params: { id: '123' } }
-```
-
-## Match
-
-The `match` function returns a function for matching strings against a path:
-
-- **path** String, `TokenData` object, or array of strings and `TokenData` objects.
-- **options** _(optional)_ (Extends [pathToRegexp](#pathToRegexp) options)
-  - **decode** Function for decoding strings to params, or `false` to disable all processing. (default: `decodeURIComponent`)
-
-```js
-const fn = match("/foo/:bar");
-```
-
-**Please note:** `path-to-regexp` is intended for ordered data (e.g. paths, hosts). It can not handle arbitrarily ordered data (e.g. query strings, URL fragments, JSON, etc).
-
-## PathToRegexp
-
-The `pathToRegexp` function returns the `regexp` for matching strings against paths, and an array of `keys` for understanding the `RegExp#exec` matches.
-
-- **path** String, `TokenData` object, or array of strings and `TokenData` objects.
-- **options** _(optional)_ (See [parse](#parse) for more options)
-  - **sensitive** Regexp will be case sensitive. (default: `false`)
-  - **end** Validate the match reaches the end of the string. (default: `true`)
-  - **delimiter** The default delimiter for segments, e.g. `[^/]` for `:named` parameters. (default: `'/'`)
-  - **trailing** Allows optional trailing delimiter to match. (default: `true`)
-
-```js
-const { regexp, keys } = pathToRegexp("/foo/:bar");
-
-regexp.exec("/foo/123"); //=> ["/foo/123", "123"]
-```
-
-## Compile ("Reverse" Path-To-RegExp)
-
-The `compile` function will return a function for transforming parameters into a valid path:
-
-- **path** A string or `TokenData` object.
-- **options** (See [parse](#parse) for more options)
-  - **delimiter** The default delimiter for segments, e.g. `[^/]` for `:named` parameters. (default: `'/'`)
-  - **encode** Function for encoding input strings for output into the path, or `false` to disable entirely. (default: `encodeURIComponent`)
-
-```js
-const toPath = compile("/user/:id");
-
-toPath({ id: "name" }); //=> "/user/name"
-toPath({ id: "café" }); //=> "/user/caf%C3%A9"
-
-const toPathRepeated = compile("/*segment");
-
-toPathRepeated({ segment: ["foo"] }); //=> "/foo"
-toPathRepeated({ segment: ["a", "b", "c"] }); //=> "/a/b/c"
-
-// When disabling `encode`, you need to make sure inputs are encoded correctly. No arrays are accepted.
-const toPathRaw = compile("/user/:id", { encode: false });
-
-toPathRaw({ id: "%3A%2F" }); //=> "/user/%3A%2F"
-```
-
-## Stringify
-
-Transform a `TokenData` object to a Path-to-RegExp string.
-
-- **data** A `TokenData` object.
-
-```js
-const data = {
-  tokens: [
-    { type: "text", value: "/" },
-    { type: "param", name: "foo" },
-  ],
-};
-
-const path = stringify(data); //=> "/:foo"
-```
-
-## Developers
-
-- If you are rewriting paths with match and compile, consider using `encode: false` and `decode: false` to keep raw paths passed around.
-- To ensure matches work on paths containing characters usually encoded, such as emoji, consider using [encodeurl](https://github.com/pillarjs/encodeurl) for `encodePath`.
-
-### Parse
-
-The `parse` function accepts a string and returns `TokenData`, which can be used with `match` and `compile`.
-
-- **path** A string.
-- **options** _(optional)_
-  - **encodePath** A function for encoding input strings. (default: `x => x`, recommended: [`encodeurl`](https://github.com/pillarjs/encodeurl))
-
-### Tokens
-
-`TokenData` has two properties:
-
-- **tokens** A sequence of tokens, currently of types `text`, `parameter`, `wildcard`, or `group`.
-- **originalPath** The original path used with `parse`, shown in error messages to assist debugging.
-
-### Custom path
-
-In some applications you may not be able to use the `path-to-regexp` syntax, but you still want to use this library for `match` and `compile`. For example:
-
-```js
-import { match } from "path-to-regexp";
-
-const tokens = [
-  { type: "text", value: "/" },
-  { type: "parameter", name: "foo" },
-];
-const originalPath = "/[foo]"; // To help debug error messages.
-const path = { tokens, originalPath };
-const fn = match(path);
-
-fn("/test"); //=> { path: '/test', index: 0, params: { foo: 'test' } }
-```
-
-## Errors
-
-An effort has been made to ensure ambiguous paths from previous releases throw an error. This means you might be seeing an error when things worked before.
-
-### Missing parameter name
-
-Parameter names must be provided after `:` or `*`, for example `/*path`. They can be valid JavaScript identifiers (e.g. `:myName`) or JSON strings (`:"my-name"`).
-
-### Unexpected `?` or `+`
-
-In past releases, `?`, `*`, and `+` were used to denote optional or repeating parameters. As an alternative, try these:
-
-- For optional (`?`), use braces: `/file{.:ext}`.
-- For one or more (`+`), use a wildcard: `/*path`.
-- For zero or more (`*`), use both: `/files{/*path}`.
-
-### Unexpected `(`, `)`, `[`, `]`, etc.
-
-Previous versions of Path-to-RegExp used these for RegExp features. This version no longer supports them so they've been reserved to avoid ambiguity. To match these characters literally, escape them with a backslash, e.g. `"\\("`.
-
-### Unterminated quote
-
-Parameter names can be wrapped in double quote characters, and this error means you forgot to close the quote character. For example, `:"foo`.
-
-### Express <= 4.x
-
-Path-To-RegExp breaks compatibility with Express <= `4.x` in the following ways:
-
-- The wildcard `*` must have a name and matches the behavior of parameters `:`.
-- The optional character `?` is no longer supported, use braces instead: `/:file{.:ext}`.
-- Regexp characters are not supported.
-- Some characters have been reserved to avoid confusion during upgrade (`()[]?+!`).
-- Parameter names now support valid JavaScript identifiers, or quoted like `:"this"`.

-Determine address of proxied request
-
-## Install
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install proxy-addr
-```
-
-## API
-
-```js
-var proxyaddr = require('proxy-addr')
-```
-
-### proxyaddr(req, trust)
-
-Return the address of the request, using the given `trust` parameter.
-
-The `trust` argument is a function that returns `true` if you trust
-the address, `false` if you don't. The closest untrusted address is
-returned.
-
-```js
-proxyaddr(req, function (addr) { return addr === '127.0.0.1' })
-proxyaddr(req, function (addr, i) { return i < 1 })
-```
-
-The `trust` arugment may also be a single IP address string or an
-array of trusted addresses, as plain IP addresses, CIDR-formatted
-strings, or IP/netmask strings.
-
-```js
-proxyaddr(req, '127.0.0.1')
-proxyaddr(req, ['127.0.0.0/8', '10.0.0.0/8'])
-proxyaddr(req, ['127.0.0.0/255.0.0.0', '192.168.0.0/255.255.0.0'])
-```
-
-This module also supports IPv6. Your IPv6 addresses will be normalized
-automatically (i.e. `fe80::00ed:1` equals `fe80:0:0:0:0:0:ed:1`).
-
-```js
-proxyaddr(req, '::1')
-proxyaddr(req, ['::1/128', 'fe80::/10'])
-```
-
-This module will automatically work with IPv4-mapped IPv6 addresses
-as well to support node.js in IPv6-only mode. This means that you do
-not have to specify both `::ffff:a00:1` and `10.0.0.1`.
-
-As a convenience, this module also takes certain pre-defined names
-in addition to IP addresses, which expand into IP addresses:
-
-```js
-proxyaddr(req, 'loopback')
-proxyaddr(req, ['loopback', 'fc00:ac:1ab5:fff::1/64'])
-```
-
-  * `loopback`: IPv4 and IPv6 loopback addresses (like `::1` and
-    `127.0.0.1`).
-  * `linklocal`: IPv4 and IPv6 link-local addresses (like
-    `fe80::1:1:1:1` and `169.254.0.1`).
-  * `uniquelocal`: IPv4 private addresses and IPv6 unique-local
-    addresses (like `fc00:ac:1ab5:fff::1` and `192.168.0.1`).
-
-When `trust` is specified as a function, it will be called for each
-address to determine if it is a trusted address. The function is
-given two arguments: `addr` and `i`, where `addr` is a string of
-the address to check and `i` is a number that represents the distance
-from the socket address.
-
-### proxyaddr.all(req, [trust])
-
-Return all the addresses of the request, optionally stopping at the
-first untrusted. This array is ordered from closest to furthest
-(i.e. `arr[0] === req.connection.remoteAddress`).
-
-```js
-proxyaddr.all(req)
-```
-
-The optional `trust` argument takes the same arguments as `trust`
-does in `proxyaddr(req, trust)`.
-
-```js
-proxyaddr.all(req, 'loopback')
-```
-
-### proxyaddr.compile(val)
-
-Compiles argument `val` into a `trust` function. This function takes
-the same arguments as `trust` does in `proxyaddr(req, trust)` and
-returns a function suitable for `proxyaddr(req, trust)`.
-
-```js
-var trust = proxyaddr.compile('loopback')
-var addr = proxyaddr(req, trust)
-```
-
-This function is meant to be optimized for use against every request.
-It is recommend to compile a trust function up-front for the trusted
-configuration and pass that to `proxyaddr(req, trust)` for each request.

-
-A querystring parsing and stringifying library with some added security.
-
-Lead Maintainer: [Jordan Harband](https://github.com/ljharb)
-
-The **qs** module was originally created and maintained by [TJ Holowaychuk](https://github.com/visionmedia/node-querystring).
-
-## Usage
-
-```javascript
-var qs = require('qs');
-var assert = require('assert');
-
-var obj = qs.parse('a=c');
-assert.deepEqual(obj, { a: 'c' });
-
-var str = qs.stringify(obj);
-assert.equal(str, 'a=c');
-```
-
-### Parsing Objects
-
-[](#preventEval)
-```javascript
-qs.parse(string, [options]);
-```
-
-**qs** allows you to create nested objects within your query strings, by surrounding the name of sub-keys with square brackets `[]`.
-For example, the string `'foo[bar]=baz'` converts to:
-
-```javascript
-assert.deepEqual(qs.parse('foo[bar]=baz'), {
-    foo: {
-        bar: 'baz'
-    }
-});
-```
-
-When using the `plainObjects` option the parsed value is returned as a null object, created via `{ __proto__: null }` and as such you should be aware that prototype methods will not exist on it and a user may set those names to whatever value they like:
-
-```javascript
-var nullObject = qs.parse('a[hasOwnProperty]=b', { plainObjects: true });
-assert.deepEqual(nullObject, { a: { hasOwnProperty: 'b' } });
-```
-
-By default parameters that would overwrite properties on the object prototype are ignored, if you wish to keep the data from those fields either use `plainObjects` as mentioned above, or set `allowPrototypes` to `true` which will allow user input to overwrite those properties.
-*WARNING* It is generally a bad idea to enable this option as it can cause problems when attempting to use the properties that have been overwritten.
-Always be careful with this option.
-
-```javascript
-var protoObject = qs.parse('a[hasOwnProperty]=b', { allowPrototypes: true });
-assert.deepEqual(protoObject, { a: { hasOwnProperty: 'b' } });
-```
-
-URI encoded strings work too:
-
-```javascript
-assert.deepEqual(qs.parse('a%5Bb%5D=c'), {
-    a: { b: 'c' }
-});
-```
-
-You can also nest your objects, like `'foo[bar][baz]=foobarbaz'`:
-
-```javascript
-assert.deepEqual(qs.parse('foo[bar][baz]=foobarbaz'), {
-    foo: {
-        bar: {
-            baz: 'foobarbaz'
-        }
-    }
-});
-```
-
-By default, when nesting objects **qs** will only parse up to 5 children deep.
-This means if you attempt to parse a string like `'a[b][c][d][e][f][g][h][i]=j'` your resulting object will be:
-
-```javascript
-var expected = {
-    a: {
-        b: {
-            c: {
-                d: {
-                    e: {
-                        f: {
-                            '[g][h][i]': 'j'
-                        }
-                    }
-                }
-            }
-        }
-    }
-};
-var string = 'a[b][c][d][e][f][g][h][i]=j';
-assert.deepEqual(qs.parse(string), expected);
-```
-
-This depth can be overridden by passing a `depth` option to `qs.parse(string, [options])`:
-
-```javascript
-var deep = qs.parse('a[b][c][d][e][f][g][h][i]=j', { depth: 1 });
-assert.deepEqual(deep, { a: { b: { '[c][d][e][f][g][h][i]': 'j' } } });
-```
-
-You can configure **qs** to throw an error when parsing nested input beyond this depth using the `strictDepth` option (defaulted to false):
-
-```javascript
-try {
-    qs.parse('a[b][c][d][e][f][g][h][i]=j', { depth: 1, strictDepth: true });
-} catch (err) {
-    assert(err instanceof RangeError);
-    assert.strictEqual(err.message, 'Input depth exceeded depth option of 1 and strictDepth is true');
-}
-```
-
-The depth limit helps mitigate abuse when **qs** is used to parse user input, and it is recommended to keep it a reasonably small number. The strictDepth option adds a layer of protection by throwing an error when the limit is exceeded, allowing you to catch and handle such cases.
-
-For similar reasons, by default **qs** will only parse up to 1000 parameters. This can be overridden by passing a `parameterLimit` option:
-
-```javascript
-var limited = qs.parse('a=b&c=d', { parameterLimit: 1 });
-assert.deepEqual(limited, { a: 'b' });
-```
-
-If you want an error to be thrown whenever the a limit is exceeded (eg, `parameterLimit`, `arrayLimit`), set the `throwOnLimitExceeded` option to `true`. This option will generate a descriptive error if the query string exceeds a configured limit.
-```javascript
-try {
-    qs.parse('a=1&b=2&c=3&d=4', { parameterLimit: 3, throwOnLimitExceeded: true });
-} catch (err) {
-    assert(err instanceof Error);
-    assert.strictEqual(err.message, 'Parameter limit exceeded. Only 3 parameters allowed.');
-}
-```
-
-When `throwOnLimitExceeded` is set to `false` (default), **qs** will parse up to the specified `parameterLimit` and ignore the rest without throwing an error.
-
-To bypass the leading question mark, use `ignoreQueryPrefix`:
-
-```javascript
-var prefixed = qs.parse('?a=b&c=d', { ignoreQueryPrefix: true });
-assert.deepEqual(prefixed, { a: 'b', c: 'd' });
-```
-
-An optional delimiter can also be passed:
-
-```javascript
-var delimited = qs.parse('a=b;c=d', { delimiter: ';' });
-assert.deepEqual(delimited, { a: 'b', c: 'd' });
-```
-
-Delimiters can be a regular expression too:
-
-```javascript
-var regexed = qs.parse('a=b;c=d,e=f', { delimiter: /[;,]/ });
-assert.deepEqual(regexed, { a: 'b', c: 'd', e: 'f' });
-```
-
-Option `allowDots` can be used to enable dot notation:
-
-```javascript
-var withDots = qs.parse('a.b=c', { allowDots: true });
-assert.deepEqual(withDots, { a: { b: 'c' } });
-```
-
-Option `decodeDotInKeys` can be used to decode dots in keys
-Note: it implies `allowDots`, so `parse` will error if you set `decodeDotInKeys` to `true`, and `allowDots` to `false`.
-
-```javascript
-var withDots = qs.parse('name%252Eobj.first=John&name%252Eobj.last=Doe', { decodeDotInKeys: true });
-assert.deepEqual(withDots, { 'name.obj': { first: 'John', last: 'Doe' }});
-```
-
-Option `allowEmptyArrays` can be used to allowing empty array values in object
-```javascript
-var withEmptyArrays = qs.parse('foo[]&bar=baz', { allowEmptyArrays: true });
-assert.deepEqual(withEmptyArrays, { foo: [], bar: 'baz' });
-```
-
-Option `duplicates` can be used to change the behavior when duplicate keys are encountered
-```javascript
-assert.deepEqual(qs.parse('foo=bar&foo=baz'), { foo: ['bar', 'baz'] });
-assert.deepEqual(qs.parse('foo=bar&foo=baz', { duplicates: 'combine' }), { foo: ['bar', 'baz'] });
-assert.deepEqual(qs.parse('foo=bar&foo=baz', { duplicates: 'first' }), { foo: 'bar' });
-assert.deepEqual(qs.parse('foo=bar&foo=baz', { duplicates: 'last' }), { foo: 'baz' });
-```
-
-If you have to deal with legacy browsers or services, there's also support for decoding percent-encoded octets as iso-8859-1:
-
-```javascript
-var oldCharset = qs.parse('a=%A7', { charset: 'iso-8859-1' });
-assert.deepEqual(oldCharset, { a: '§' });
-```
-
-Some services add an initial `utf8=✓` value to forms so that old Internet Explorer versions are more likely to submit the form as utf-8.
-Additionally, the server can check the value against wrong encodings of the checkmark character and detect that a query string or `application/x-www-form-urlencoded` body was *not* sent as utf-8, eg. if the form had an `accept-charset` parameter or the containing page had a different character set.
-
-**qs** supports this mechanism via the `charsetSentinel` option.
-If specified, the `utf8` parameter will be omitted from the returned object.
-It will be used to switch to `iso-8859-1`/`utf-8` mode depending on how the checkmark is encoded.
-
-**Important**: When you specify both the `charset` option and the `charsetSentinel` option, the `charset` will be overridden when the request contains a `utf8` parameter from which the actual charset can be deduced.
-In that sense the `charset` will behave as the default charset rather than the authoritative charset.
-
-```javascript
-var detectedAsUtf8 = qs.parse('utf8=%E2%9C%93&a=%C3%B8', {
-    charset: 'iso-8859-1',
-    charsetSentinel: true
-});
-assert.deepEqual(detectedAsUtf8, { a: 'ø' });
-
-// Browsers encode the checkmark as &#10003; when submitting as iso-8859-1:
-var detectedAsIso8859_1 = qs.parse('utf8=%26%2310003%3B&a=%F8', {
-    charset: 'utf-8',
-    charsetSentinel: true
-});
-assert.deepEqual(detectedAsIso8859_1, { a: 'ø' });
-```
-
-If you want to decode the `&#...;` syntax to the actual character, you can specify the `interpretNumericEntities` option as well:
-
-```javascript
-var detectedAsIso8859_1 = qs.parse('a=%26%239786%3B', {
-    charset: 'iso-8859-1',
-    interpretNumericEntities: true
-});
-assert.deepEqual(detectedAsIso8859_1, { a: '☺' });
-```
-
-It also works when the charset has been detected in `charsetSentinel` mode.
-
-### Parsing Arrays
-
-**qs** can also parse arrays using a similar `[]` notation:
-
-```javascript
-var withArray = qs.parse('a[]=b&a[]=c');
-assert.deepEqual(withArray, { a: ['b', 'c'] });
-```
-
-You may specify an index as well:
-
-```javascript
-var withIndexes = qs.parse('a[1]=c&a[0]=b');
-assert.deepEqual(withIndexes, { a: ['b', 'c'] });
-```
-
-Note that the only difference between an index in an array and a key in an object is that the value between the brackets must be a number to create an array.
-When creating arrays with specific indices, **qs** will compact a sparse array to only the existing values preserving their order:
-
-```javascript
-var noSparse = qs.parse('a[1]=b&a[15]=c');
-assert.deepEqual(noSparse, { a: ['b', 'c'] });
-```
-
-You may also use `allowSparse` option to parse sparse arrays:
-
-```javascript
-var sparseArray = qs.parse('a[1]=2&a[3]=5', { allowSparse: true });
-assert.deepEqual(sparseArray, { a: [, '2', , '5'] });
-```
-
-Note that an empty string is also a value, and will be preserved:
-
-```javascript
-var withEmptyString = qs.parse('a[]=&a[]=b');
-assert.deepEqual(withEmptyString, { a: ['', 'b'] });
-
-var withIndexedEmptyString = qs.parse('a[0]=b&a[1]=&a[2]=c');
-assert.deepEqual(withIndexedEmptyString, { a: ['b', '', 'c'] });
-```
-
-**qs** will also limit specifying indices in an array to a maximum index of `20`.
-Any array members with an index of greater than `20` will instead be converted to an object with the index as the key.
-This is needed to handle cases when someone sent, for example, `a[999999999]` and it will take significant time to iterate over this huge array.
-
-```javascript
-var withMaxIndex = qs.parse('a[100]=b');
-assert.deepEqual(withMaxIndex, { a: { '100': 'b' } });
-```
-
-This limit can be overridden by passing an `arrayLimit` option:
-
-```javascript
-var withArrayLimit = qs.parse('a[1]=b', { arrayLimit: 0 });
-assert.deepEqual(withArrayLimit, { a: { '1': 'b' } });
-```
-
-If you want to throw an error whenever the array limit is exceeded, set the `throwOnLimitExceeded` option to `true`. This option will generate a descriptive error if the query string exceeds a configured limit.
-```javascript
-try {
-    qs.parse('a[1]=b', { arrayLimit: 0, throwOnLimitExceeded: true });
-} catch (err) {
-    assert(err instanceof Error);
-    assert.strictEqual(err.message, 'Array limit exceeded. Only 0 elements allowed in an array.');
-}
-```
-
-When `throwOnLimitExceeded` is set to `false` (default), **qs** will parse up to the specified `arrayLimit` and if the limit is exceeded, the array will instead be converted to an object with the index as the key
-
-To disable array parsing entirely, set `parseArrays` to `false`.
-
-```javascript
-var noParsingArrays = qs.parse('a[]=b', { parseArrays: false });
-assert.deepEqual(noParsingArrays, { a: { '0': 'b' } });
-```
-
-If you mix notations, **qs** will merge the two items into an object:
-
-```javascript
-var mixedNotation = qs.parse('a[0]=b&a[b]=c');
-assert.deepEqual(mixedNotation, { a: { '0': 'b', b: 'c' } });
-```
-
-You can also create arrays of objects:
-
-```javascript
-var arraysOfObjects = qs.parse('a[][b]=c');
-assert.deepEqual(arraysOfObjects, { a: [{ b: 'c' }] });
-```
-
-Some people use comma to join array, **qs** can parse it:
-```javascript
-var arraysOfObjects = qs.parse('a=b,c', { comma: true })
-assert.deepEqual(arraysOfObjects, { a: ['b', 'c'] })
-```
-(_this cannot convert nested objects, such as `a={b:1},{c:d}`_)
-
-### Parsing primitive/scalar values (numbers, booleans, null, etc)
-
-By default, all values are parsed as strings.
-This behavior will not change and is explained in [issue #91](https://github.com/ljharb/qs/issues/91).
-
-```javascript
-var primitiveValues = qs.parse('a=15&b=true&c=null');
-assert.deepEqual(primitiveValues, { a: '15', b: 'true', c: 'null' });
-```
-
-If you wish to auto-convert values which look like numbers, booleans, and other values into their primitive counterparts, you can use the [query-types Express JS middleware](https://github.com/xpepermint/query-types) which will auto-convert all request query parameters.
-
-### Stringifying
-
-[](#preventEval)
-```javascript
-qs.stringify(object, [options]);
-```
-
-When stringifying, **qs** by default URI encodes output. Objects are stringified as you would expect:
-
-```javascript
-assert.equal(qs.stringify({ a: 'b' }), 'a=b');
-assert.equal(qs.stringify({ a: { b: 'c' } }), 'a%5Bb%5D=c');
-```
-
-This encoding can be disabled by setting the `encode` option to `false`:
-
-```javascript
-var unencoded = qs.stringify({ a: { b: 'c' } }, { encode: false });
-assert.equal(unencoded, 'a[b]=c');
-```
-
-Encoding can be disabled for keys by setting the `encodeValuesOnly` option to `true`:
-```javascript
-var encodedValues = qs.stringify(
-    { a: 'b', c: ['d', 'e=f'], f: [['g'], ['h']] },
-    { encodeValuesOnly: true }
-);
-assert.equal(encodedValues,'a=b&c[0]=d&c[1]=e%3Df&f[0][0]=g&f[1][0]=h');
-```
-
-This encoding can also be replaced by a custom encoding method set as `encoder` option:
-
-```javascript
-var encoded = qs.stringify({ a: { b: 'c' } }, { encoder: function (str) {
-    // Passed in values `a`, `b`, `c`
-    return // Return encoded string
-}})
-```
-
-_(Note: the `encoder` option does not apply if `encode` is `false`)_
-
-Analogue to the `encoder` there is a `decoder` option for `parse` to override decoding of properties and values:
-
-```javascript
-var decoded = qs.parse('x=z', { decoder: function (str) {
-    // Passed in values `x`, `z`
-    return // Return decoded string
-}})
-```
-
-You can encode keys and values using different logic by using the type argument provided to the encoder:
-
-```javascript
-var encoded = qs.stringify({ a: { b: 'c' } }, { encoder: function (str, defaultEncoder, charset, type) {
-    if (type === 'key') {
-        return // Encoded key
-    } else if (type === 'value') {
-        return // Encoded value
-    }
-}})
-```
-
-The type argument is also provided to the decoder:
-
-```javascript
-var decoded = qs.parse('x=z', { decoder: function (str, defaultDecoder, charset, type) {
-    if (type === 'key') {
-        return // Decoded key
-    } else if (type === 'value') {
-        return // Decoded value
-    }
-}})
-```
-
-Examples beyond this point will be shown as though the output is not URI encoded for clarity.
-Please note that the return values in these cases *will* be URI encoded during real usage.
-
-When arrays are stringified, they follow the `arrayFormat` option, which defaults to `indices`:
-
-```javascript
-qs.stringify({ a: ['b', 'c', 'd'] });
-// 'a[0]=b&a[1]=c&a[2]=d'
-```
-
-You may override this by setting the `indices` option to `false`, or to be more explicit, the `arrayFormat` option to `repeat`:
-
-```javascript
-qs.stringify({ a: ['b', 'c', 'd'] }, { indices: false });
-// 'a=b&a=c&a=d'
-```
-
-You may use the `arrayFormat` option to specify the format of the output array:
-
-```javascript
-qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'indices' })
-// 'a[0]=b&a[1]=c'
-qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'brackets' })
-// 'a[]=b&a[]=c'
-qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'repeat' })
-// 'a=b&a=c'
-qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'comma' })
-// 'a=b,c'
-```
-
-Note: when using `arrayFormat` set to `'comma'`, you can also pass the `commaRoundTrip` option set to `true` or `false`, to append `[]` on single-item arrays, so that they can round trip through a parse.
-
-When objects are stringified, by default they use bracket notation:
-
-```javascript
-qs.stringify({ a: { b: { c: 'd', e: 'f' } } });
-// 'a[b][c]=d&a[b][e]=f'
-```
-
-You may override this to use dot notation by setting the `allowDots` option to `true`:
-
-```javascript
-qs.stringify({ a: { b: { c: 'd', e: 'f' } } }, { allowDots: true });
-// 'a.b.c=d&a.b.e=f'
-```
-
-You may encode the dot notation in the keys of object with option `encodeDotInKeys` by setting it to `true`:
-Note: it implies `allowDots`, so `stringify` will error if you set `decodeDotInKeys` to `true`, and `allowDots` to `false`.
-Caveat: when `encodeValuesOnly` is `true` as well as `encodeDotInKeys`, only dots in keys and nothing else will be encoded.
-```javascript
-qs.stringify({ "name.obj": { "first": "John", "last": "Doe" } }, { allowDots: true, encodeDotInKeys: true })
-// 'name%252Eobj.first=John&name%252Eobj.last=Doe'
-```
-
-You may allow empty array values by setting the `allowEmptyArrays` option to `true`:
-```javascript
-qs.stringify({ foo: [], bar: 'baz' }, { allowEmptyArrays: true });
-// 'foo[]&bar=baz'
-```
-
-Empty strings and null values will omit the value, but the equals sign (=) remains in place:
-
-```javascript
-assert.equal(qs.stringify({ a: '' }), 'a=');
-```
-
-Key with no values (such as an empty object or array) will return nothing:
-
-```javascript
-assert.equal(qs.stringify({ a: [] }), '');
-assert.equal(qs.stringify({ a: {} }), '');
-assert.equal(qs.stringify({ a: [{}] }), '');
-assert.equal(qs.stringify({ a: { b: []} }), '');
-assert.equal(qs.stringify({ a: { b: {}} }), '');
-```
-
-Properties that are set to `undefined` will be omitted entirely:
-
-```javascript
-assert.equal(qs.stringify({ a: null, b: undefined }), 'a=');
-```
-
-The query string may optionally be prepended with a question mark:
-
-```javascript
-assert.equal(qs.stringify({ a: 'b', c: 'd' }, { addQueryPrefix: true }), '?a=b&c=d');
-```
-
-The delimiter may be overridden with stringify as well:
-
-```javascript
-assert.equal(qs.stringify({ a: 'b', c: 'd' }, { delimiter: ';' }), 'a=b;c=d');
-```
-
-If you only want to override the serialization of `Date` objects, you can provide a `serializeDate` option:
-
-```javascript
-var date = new Date(7);
-assert.equal(qs.stringify({ a: date }), 'a=1970-01-01T00:00:00.007Z'.replace(/:/g, '%3A'));
-assert.equal(
-    qs.stringify({ a: date }, { serializeDate: function (d) { return d.getTime(); } }),
-    'a=7'
-);
-```
-
-You may use the `sort` option to affect the order of parameter keys:
-
-```javascript
-function alphabeticalSort(a, b) {
-    return a.localeCompare(b);
-}
-assert.equal(qs.stringify({ a: 'c', z: 'y', b : 'f' }, { sort: alphabeticalSort }), 'a=c&b=f&z=y');
-```
-
-Finally, you can use the `filter` option to restrict which keys will be included in the stringified output.
-If you pass a function, it will be called for each key to obtain the replacement value.
-Otherwise, if you pass an array, it will be used to select properties and array indices for stringification:
-
-```javascript
-function filterFunc(prefix, value) {
-    if (prefix == 'b') {
-        // Return an `undefined` value to omit a property.
-        return;
-    }
-    if (prefix == 'e[f]') {
-        return value.getTime();
-    }
-    if (prefix == 'e[g][0]') {
-        return value * 2;
-    }
-    return value;
-}
-qs.stringify({ a: 'b', c: 'd', e: { f: new Date(123), g: [2] } }, { filter: filterFunc });
-// 'a=b&c=d&e[f]=123&e[g][0]=4'
-qs.stringify({ a: 'b', c: 'd', e: 'f' }, { filter: ['a', 'e'] });
-// 'a=b&e=f'
-qs.stringify({ a: ['b', 'c', 'd'], e: 'f' }, { filter: ['a', 0, 2] });
-// 'a[0]=b&a[2]=d'
-```
-
-You could also use `filter` to inject custom serialization for user defined types.
-Consider you're working with some api that expects query strings of the format for ranges:
-
-```
-https://domain.com/endpoint?range=30...70
-```
-
-For which you model as:
-
-```javascript
-class Range {
-    constructor(from, to) {
-        this.from = from;
-        this.to = to;
-    }
-}
-```
-
-You could _inject_ a custom serializer to handle values of this type:
-
-```javascript
-qs.stringify(
-    {
-        range: new Range(30, 70),
-    },
-    {
-        filter: (prefix, value) => {
-            if (value instanceof Range) {
-                return `${value.from}...${value.to}`;
-            }
-            // serialize the usual way
-            return value;
-        },
-    }
-);
-// range=30...70
-```
-
-### Handling of `null` values
-
-By default, `null` values are treated like empty strings:
-
-```javascript
-var withNull = qs.stringify({ a: null, b: '' });
-assert.equal(withNull, 'a=&b=');
-```
-
-Parsing does not distinguish between parameters with and without equal signs.
-Both are converted to empty strings.
-
-```javascript
-var equalsInsensitive = qs.parse('a&b=');
-assert.deepEqual(equalsInsensitive, { a: '', b: '' });
-```
-
-To distinguish between `null` values and empty strings use the `strictNullHandling` flag. In the result string the `null`
-values have no `=` sign:
-
-```javascript
-var strictNull = qs.stringify({ a: null, b: '' }, { strictNullHandling: true });
-assert.equal(strictNull, 'a&b=');
-```
-
-To parse values without `=` back to `null` use the `strictNullHandling` flag:
-
-```javascript
-var parsedStrictNull = qs.parse('a&b=', { strictNullHandling: true });
-assert.deepEqual(parsedStrictNull, { a: null, b: '' });
-```
-
-To completely skip rendering keys with `null` values, use the `skipNulls` flag:
-
-```javascript
-var nullsSkipped = qs.stringify({ a: 'b', c: null}, { skipNulls: true });
-assert.equal(nullsSkipped, 'a=b');
-```
-
-If you're communicating with legacy systems, you can switch to `iso-8859-1` using the `charset` option:
-
-```javascript
-var iso = qs.stringify({ æ: 'æ' }, { charset: 'iso-8859-1' });
-assert.equal(iso, '%E6=%E6');
-```
-
-Characters that don't exist in `iso-8859-1` will be converted to numeric entities, similar to what browsers do:
-
-```javascript
-var numeric = qs.stringify({ a: '☺' }, { charset: 'iso-8859-1' });
-assert.equal(numeric, 'a=%26%239786%3B');
-```
-
-You can use the `charsetSentinel` option to announce the character by including an `utf8=✓` parameter with the proper encoding if the checkmark, similar to what Ruby on Rails and others do when submitting forms.
-
-```javascript
-var sentinel = qs.stringify({ a: '☺' }, { charsetSentinel: true });
-assert.equal(sentinel, 'utf8=%E2%9C%93&a=%E2%98%BA');
-
-var isoSentinel = qs.stringify({ a: 'æ' }, { charsetSentinel: true, charset: 'iso-8859-1' });
-assert.equal(isoSentinel, 'utf8=%26%2310003%3B&a=%E6');
-```
-
-### Dealing with special character sets
-
-By default the encoding and decoding of characters is done in `utf-8`, and `iso-8859-1` support is also built in via the `charset` parameter.
-
-If you wish to encode querystrings to a different character set (i.e.
-[Shift JIS](https://en.wikipedia.org/wiki/Shift_JIS)) you can use the
-[`qs-iconv`](https://github.com/martinheidegger/qs-iconv) library:
-
-```javascript
-var encoder = require('qs-iconv/encoder')('shift_jis');
-var shiftJISEncoded = qs.stringify({ a: 'こんにちは！' }, { encoder: encoder });
-assert.equal(shiftJISEncoded, 'a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I');
-```
-
-This also works for decoding of query strings:
-
-```javascript
-var decoder = require('qs-iconv/decoder')('shift_jis');
-var obj = qs.parse('a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I', { decoder: decoder });
-assert.deepEqual(obj, { a: 'こんにちは！' });
-```
-
-### RFC 3986 and RFC 1738 space encoding
-
-RFC3986 used as default option and encodes ' ' to *%20* which is backward compatible.
-In the same time, output can be stringified as per RFC1738 with ' ' equal to '+'.
-
-```
-assert.equal(qs.stringify({ a: 'b c' }), 'a=b%20c');
-assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC3986' }), 'a=b%20c');
-assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC1738' }), 'a=b+c');
-```

-
-Range header field parser.
-
-## Installation
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install range-parser
-```
-
-## API
-
-<!-- eslint-disable no-unused-vars -->
-
-```js
-var parseRange = require('range-parser')
-```
-
-### parseRange(size, header, options)
-
-Parse the given `header` string where `size` is the maximum size of the resource.
-An array of ranges will be returned or negative numbers indicating an error parsing.
-
-  * `-2` signals a malformed header string
-  * `-1` signals an unsatisfiable range
-
-<!-- eslint-disable no-undef -->
-
-```js
-// parse header from request
-var range = parseRange(size, req.headers.range)
-
-// the type of the range
-if (range.type === 'bytes') {
-  // the ranges
-  range.forEach(function (r) {
-    // do something with r.start and r.end
-  })
-}
-```
-
-#### Options
-
-These properties are accepted in the options object.
-
-##### combine
-
-Specifies if overlapping & adjacent ranges should be combined, defaults to `false`.
-When `true`, ranges will be combined and returned as if they were specified that
-way in the header.
-
-<!-- eslint-disable no-undef -->
-
-```js
-parseRange(100, 'bytes=50-55,0-10,5-10,56-60', { combine: true })
-// => [
-//      { start: 0,  end: 10 },
-//      { start: 50, end: 60 }
-//    ]

-
-Gets the entire buffer of a stream either as a `Buffer` or a string.
-Validates the stream's length against an expected length and maximum limit.
-Ideal for parsing request bodies.
-
-## Install
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install raw-body
-```
-
-### TypeScript
-
-This module includes a [TypeScript](https://www.typescriptlang.org/)
-declaration file to enable auto complete in compatible editors and type
-information for TypeScript projects. This module depends on the Node.js
-types, so install `@types/node`:
-
-```sh
-$ npm install @types/node
-```
-
-## API
-
-```js
-var getRawBody = require('raw-body')
-```
-
-### getRawBody(stream, [options], [callback])
-
-**Returns a promise if no callback specified and global `Promise` exists.**
-
-Options:
-
-- `length` - The length of the stream.
-  If the contents of the stream do not add up to this length,
-  an `400` error code is returned.
-- `limit` - The byte limit of the body.
-  This is the number of bytes or any string format supported by
-  [bytes](https://www.npmjs.com/package/bytes),
-  for example `1000`, `'500kb'` or `'3mb'`.
-  If the body ends up being larger than this limit,
-  a `413` error code is returned.
-- `encoding` - The encoding to use to decode the body into a string.
-  By default, a `Buffer` instance will be returned when no encoding is specified.
-  Most likely, you want `utf-8`, so setting `encoding` to `true` will decode as `utf-8`.
-  You can use any type of encoding supported by [iconv-lite](https://www.npmjs.org/package/iconv-lite#readme).
-
-You can also pass a string in place of options to just specify the encoding.
-
-If an error occurs, the stream will be paused, everything unpiped,
-and you are responsible for correctly disposing the stream.
-For HTTP requests, you may need to finish consuming the stream if
-you want to keep the socket open for future requests. For streams
-that use file descriptors, you should `stream.destroy()` or
-`stream.close()` to prevent leaks.
-
-## Errors
-
-This module creates errors depending on the error condition during reading.
-The error may be an error from the underlying Node.js implementation, but is
-otherwise an error created by this module, which has the following attributes:
-
-  * `limit` - the limit in bytes
-  * `length` and `expected` - the expected length of the stream
-  * `received` - the received bytes
-  * `encoding` - the invalid encoding
-  * `status` and `statusCode` - the corresponding status code for the error
-  * `type` - the error type
-
-### Types
-
-The errors from this module have a `type` property which allows for the programmatic
-determination of the type of error returned.
-
-#### encoding.unsupported
-
-This error will occur when the `encoding` option is specified, but the value does
-not map to an encoding supported by the [iconv-lite](https://www.npmjs.org/package/iconv-lite#readme)
-module.
-
-#### entity.too.large
-
-This error will occur when the `limit` option is specified, but the stream has
-an entity that is larger.
-
-#### request.aborted
-
-This error will occur when the request stream is aborted by the client before
-reading the body has finished.
-
-#### request.size.invalid
-
-This error will occur when the `length` option is specified, but the stream has
-emitted more bytes.
-
-#### stream.encoding.set
-
-This error will occur when the given stream has an encoding set on it, making it
-a decoded stream. The stream should not have an encoding set and is expected to
-emit `Buffer` objects.
-
-#### stream.not.readable
-
-This error will occur when the given stream is not readable.
-
-## Examples
-
-### Simple Express example
-
-```js
-var contentType = require('content-type')
-var express = require('express')
-var getRawBody = require('raw-body')
-
-var app = express()
-
-app.use(function (req, res, next) {
-  getRawBody(req, {
-    length: req.headers['content-length'],
-    limit: '1mb',
-    encoding: contentType.parse(req).parameters.charset
-  }, function (err, string) {
-    if (err) return next(err)
-    req.text = string
-    next()
-  })
-})
-
-// now access req.text
-```
-
-### Simple Koa example
-
-```js
-var contentType = require('content-type')
-var getRawBody = require('raw-body')
-var koa = require('koa')
-
-var app = koa()
-
-app.use(function * (next) {
-  this.text = yield getRawBody(this.req, {
-    length: this.req.headers['content-length'],
-    limit: '1mb',
-    encoding: contentType.parse(this.req).parameters.charset
-  })
-  yield next
-})
-
-// now access this.text
-```
-
-### Using as a promise
-
-To use this library as a promise, simply omit the `callback` and a promise is
-returned, provided that a global `Promise` is defined.
-
-```js
-var getRawBody = require('raw-body')
-var http = require('http')
-
-var server = http.createServer(function (req, res) {
-  getRawBody(req)
-    .then(function (buf) {
-      res.statusCode = 200
-      res.end(buf.length + ' bytes submitted')
-    })
-    .catch(function (err) {
-      res.statusCode = 500
-      res.end(err.message)
-    })
-})
-
-server.listen(3000)
-```
-
-### Using with TypeScript
-
-```ts
-import * as getRawBody from 'raw-body';
-import * as http from 'http';
-
-const server = http.createServer((req, res) => {
-  getRawBody(req)
-  .then((buf) => {
-    res.statusCode = 200;
-    res.end(buf.length + ' bytes submitted');
-  })
-  .catch((err) => {
-    res.statusCode = err.statusCode;
-    res.end(err.message);
-  });
-});
-
-server.listen(3000);
-```

-2.2.0 / 2025-03-26
-==================
-
-* Remove `setImmediate` support check
-* Restore `debug` dependency
-
-2.1.0 / 2025-02-10
-==================
-
-* Updated `engines` field to Node@18 or higher
-* Remove `Object.setPrototypeOf` polyfill
-* Use `Array.flat` instead of `array-flatten` package
-* Replace `methods` dependency with standard library
-* deps: parseurl@^1.3.3
-* deps: is-promise@^4.0.0
-* Replace `utils-merge` dependency with `Object.assign`

-
-2.0.0 / 2024-09-09
-==================
-
-* Drop support for node <18
-* deps: path-to-regexp@^8.0.0
-  - Drop support for partial capture group `router.route('/user(s?)/:user/:op')` but still have optional non-capture `/user{s}/:user/:op`
-  - `:name?` becomes `{:name}`
-  - `:name*` becomes `*name`.
-  - The splat change also changes splat from strings to an array of strings
-  - Optional splats become `{*name}`
-  - `:name+` becomes `*name` and thus equivalent to `*name` so I dropped those tests
-  - Strings as regular expressions are fully removed, need to be converted to native regular expressions
-
-2.0.0-beta.2 / 2024-03-20

-      `/:foo(.*)` only captures as `req.params.foo` and not available as
-      `req.params[0]`.
-    - Regular expressions can only be used in a matching group.
-      `/\\d+` is no longer valid and must be written as `/(\\d+)`.
-    - Matching groups are now literal regular expressions.
-      `:foo` named captures can no longer be included inside a capture group.
-    - Special `*` path segment behavior removed.
-      `/foo/*/bar` will match a literal `*` as the middle segment.

-Simple middleware-style router
-
-## Installation
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```bash
-$ npm install router
-```
-
-## API
-
-```js
-var finalhandler = require('finalhandler')
-var http = require('http')
-var Router = require('router')
-
-var router = Router()
-router.get('/', function (req, res) {
-  res.setHeader('Content-Type', 'text/plain; charset=utf-8')
-  res.end('Hello World!')
-})
-
-var server = http.createServer(function (req, res) {
-  router(req, res, finalhandler(req, res))
-})
-
-server.listen(3000)
-```
-
-This module is currently an extracted version from the Express project,
-but with the main change being it can be used with a plain `http.createServer`
-object or other web frameworks by removing Express-specific API calls.
-
-## Router(options)
-
-Options
-
-- `strict`        - When `false` trailing slashes are optional (default: `false`)
-- `caseSensitive` - When `true` the routing will be case sensitive. (default: `false`)
-- `mergeParams`   - When `true` any `req.params` passed to the router will be
-  merged into the router's `req.params`. (default: `false`) ([example](#example-using-mergeparams))
-
-Returns a function with the signature `router(req, res, callback)` where
-`callback([err])` must be provided to handle errors and fall-through from
-not handling requests.
-
-### router.use([path], ...middleware)
-
-Use the given [middleware function](#middleware) for all http methods on the
-given `path`, defaulting to the root path.
-
-`router` does not automatically see `use` as a handler. As such, it will not
-consider it one for handling `OPTIONS` requests.
-
-* Note: If a `path` is specified, that `path` is stripped from the start of
-  `req.url`.
-
-<!-- eslint-disable no-undef -->
-
-```js
-router.use(function (req, res, next) {
-  // do your things
-
-  // continue to the next middleware
-  // the request will stall if this is not called
-  next()
-
-  // note: you should NOT call `next` if you have begun writing to the response
-})
-```
-
-[Middleware](#middleware) can themselves use `next('router')` at any time to
-exit the current router instance completely, invoking the top-level callback.
-
-### router\[method](path, ...[middleware], handler)
-
-The [http methods](https://github.com/jshttp/methods/blob/master/index.js) provide
-the routing functionality in `router`.
-
-Method middleware and handlers follow usual [middleware](#middleware) behavior,
-except they will only be called when the method and path match the request.
-
-<!-- eslint-disable no-undef -->
-
-```js
-// handle a `GET` request
-router.get('/', function (req, res) {
-  res.setHeader('Content-Type', 'text/plain; charset=utf-8')
-  res.end('Hello World!')
-})
-```
-
-[Middleware](#middleware) given before the handler have one additional trick,
-they may invoke `next('route')`. Calling `next('route')` bypasses the remaining
-middleware and the handler mounted for this route, passing the request to the
-next route suitable for handling this request.
-
-Route handlers and middleware can themselves use `next('router')` at any time
-to exit the current router instance completely, invoking the top-level callback.
-
-### router.param(name, param_middleware)
-
-Maps the specified path parameter `name` to a specialized param-capturing middleware.
-
-This function positions the middleware in the same stack as `.use`.
-
-The function can optionally return a `Promise` object. If a `Promise` object
-is returned from the function, the router will attach an `onRejected` callback
-using `.then`. If the promise is rejected, `next` will be called with the
-rejected value, or an error if the value is falsy.
-
-Parameter mapping is used to provide pre-conditions to routes
-which use normalized placeholders. For example a _:user_id_ parameter
-could automatically load a user's information from the database without
-any additional code:
-
-<!-- eslint-disable no-undef -->
-
-```js
-router.param('user_id', function (req, res, next, id) {
-  User.find(id, function (err, user) {
-    if (err) {
-      return next(err)
-    } else if (!user) {
-      return next(new Error('failed to load user'))
-    }
-    req.user = user
-
-    // continue processing the request
-    next()
-  })
-})
-```
-
-### router.route(path)
-
-Creates an instance of a single `Route` for the given `path`.
-(See `Router.Route` below)
-
-Routes can be used to handle http `methods` with their own, optional middleware.
-
-Using `router.route(path)` is a recommended approach to avoiding duplicate
-route naming and thus typo errors.
-
-<!-- eslint-disable no-undef, no-unused-vars -->
-
-```js
-var api = router.route('/api/')
-```
-
-## Router.Route(path)
-
-Represents a single route as an instance that can be used to handle http
-`methods` with it's own, optional middleware.
-
-### route\[method](handler)
-
-These are functions which you can directly call on a route to register a new
-`handler` for the `method` on the route.
-
-<!-- eslint-disable no-undef -->
-
-```js
-// handle a `GET` request
-var status = router.route('/status')
-
-status.get(function (req, res) {
-  res.setHeader('Content-Type', 'text/plain; charset=utf-8')
-  res.end('All Systems Green!')
-})
-```
-
-### route.all(handler)
-
-Adds a handler for all HTTP methods to this route.
-
-The handler can behave like middleware and call `next` to continue processing
-rather than responding.
-
-<!-- eslint-disable no-undef -->
-
-```js
-router.route('/')
-  .all(function (req, res, next) {
-    next()
-  })
-  .all(checkSomething)
-  .get(function (req, res) {
-    res.setHeader('Content-Type', 'text/plain; charset=utf-8')
-    res.end('Hello World!')
-  })
-```
-
-## Middleware
-
-Middleware (and method handlers) are functions that follow specific function
-parameters and have defined behavior when used with `router`. The most common
-format is with three parameters - "req", "res" and "next".
-
-- `req`  - This is a [HTTP incoming message](https://nodejs.org/api/http.html#http_http_incomingmessage) instance.
-- `res`  - This is a [HTTP server response](https://nodejs.org/api/http.html#http_class_http_serverresponse) instance.
-- `next` - Calling this function that tells `router` to proceed to the next matching middleware or method handler. It accepts an error as the first argument.
-
-The function can optionally return a `Promise` object. If a `Promise` object
-is returned from the function, the router will attach an `onRejected` callback
-using `.then`. If the promise is rejected, `next` will be called with the
-rejected value, or an error if the value is falsy.
-
-Middleware and method handlers can also be defined with four arguments. When
-the function has four parameters defined, the first argument is an error and
-subsequent arguments remain, becoming - "err", "req", "res", "next". These
-functions are "error handling middleware", and can be used for handling
-errors that occurred in previous handlers (E.g. from calling `next(err)`).
-This is most used when you want to define arbitrary rendering of errors.
-
-<!-- eslint-disable no-undef -->
-
-```js
-router.get('/error_route', function (req, res, next) {
-  return next(new Error('Bad Request'))
-})
-
-router.use(function (err, req, res, next) {
-  res.end(err.message) //= > "Bad Request"
-})
-```
-
-Error handling middleware will **only** be invoked when an error was given. As
-long as the error is in the pipeline, normal middleware and handlers will be
-bypassed - only error handling middleware will be invoked with an error.
-
-## Examples
-
-```js
-// import our modules
-var http = require('http')
-var Router = require('router')
-var finalhandler = require('finalhandler')
-var compression = require('compression')
-var bodyParser = require('body-parser')
-
-// store our message to display
-var message = 'Hello World!'
-
-// initialize the router & server and add a final callback.
-var router = Router()
-var server = http.createServer(function onRequest (req, res) {
-  router(req, res, finalhandler(req, res))
-})
-
-// use some middleware and compress all outgoing responses
-router.use(compression())
-
-// handle `GET` requests to `/message`
-router.get('/message', function (req, res) {
-  res.statusCode = 200
-  res.setHeader('Content-Type', 'text/plain; charset=utf-8')
-  res.end(message + '\n')
-})
-
-// create and mount a new router for our API
-var api = Router()
-router.use('/api/', api)
-
-// add a body parsing middleware to our API
-api.use(bodyParser.json())
-
-// handle `PATCH` requests to `/api/set-message`
-api.patch('/set-message', function (req, res) {
-  if (req.body.value) {
-    message = req.body.value
-
-    res.statusCode = 200
-    res.setHeader('Content-Type', 'text/plain; charset=utf-8')
-    res.end(message + '\n')
-  } else {
-    res.statusCode = 400
-    res.setHeader('Content-Type', 'text/plain; charset=utf-8')
-    res.end('Invalid API Syntax\n')
-  }
-})
-
-// make our http server listen to connections
-server.listen(8080)
-```
-
-You can get the message by running this command in your terminal,
- or navigating to `127.0.0.1:8080` in a web browser.
-```bash
-curl http://127.0.0.1:8080
-```
-
-You can set the message by sending it a `PATCH` request via this command:
-```bash
-curl http://127.0.0.1:8080/api/set-message -X PATCH -H "Content-Type: application/json" -d '{"value":"Cats!"}'
-```
-
-### Example using mergeParams
-
-```js
-var http = require('http')
-var Router = require('router')
-var finalhandler = require('finalhandler')
-
-// this example is about the mergeParams option
-var opts = { mergeParams: true }
-
-// make a router with out special options
-var router = Router(opts)
-var server = http.createServer(function onRequest (req, res) {
-  // set something to be passed into the router
-  req.params = { type: 'kitten' }
-
-  router(req, res, finalhandler(req, res))
-})
-
-router.get('/', function (req, res) {
-  res.statusCode = 200
-  res.setHeader('Content-Type', 'text/plain; charset=utf-8')
-
-  // with respond with the the params that were passed in
-  res.end(req.params.type + '\n')
-})
-
-// make another router with our options
-var handler = Router(opts)
-
-// mount our new router to a route that accepts a param
-router.use('/:path', handler)
-
-handler.get('/', function (req, res) {
-  res.statusCode = 200
-  res.setHeader('Content-Type', 'text/plain; charset=utf-8')
-
-  // will respond with the param of the router's parent route
-  res.end(req.params.path + '\n')
-})
-
-// make our http server listen to connections
-server.listen(8080)
-```
-
-Now you can get the type, or what path you are requesting:
-```bash
-curl http://127.0.0.1:8080
-> kitten
-curl http://127.0.0.1:8080/such_path
-> such_path
-```
-
-### Example of advanced `.route()` usage
-
-This example shows how to implement routes where there is a custom
-handler to execute when the path matched, but no methods matched.
-Without any special handling, this would be treated as just a
-generic non-match by `router` (which typically results in a 404),
-but with a custom handler, a `405 Method Not Allowed` can be sent.
-
-```js
-var http = require('http')
-var finalhandler = require('finalhandler')
-var Router = require('router')
-
-// create the router and server
-var router = new Router()
-var server = http.createServer(function onRequest (req, res) {
-  router(req, res, finalhandler(req, res))
-})
-
-// register a route and add all methods
-router.route('/pet/:id')
-  .get(function (req, res) {
-    // this is GET /pet/:id
-    res.setHeader('Content-Type', 'application/json')
-    res.end(JSON.stringify({ name: 'tobi' }))
-  })
-  .delete(function (req, res) {
-    // this is DELETE /pet/:id
-    res.end()
-  })
-  .all(function (req, res) {
-    // this is called for all other methods not
-    // defined above for /pet/:id
-    res.statusCode = 405
-    res.end()
-  })
-
-// make our http server listen to connections
-server.listen(8080)
-```

-
-### Finding problematic bits of code using grep
-
-Just run `grep -nrE '[^a-zA-Z](Slow)?Buffer\s*\(' --exclude-dir node_modules`.
-
-It will find all the potentially unsafe places in your own code (with some considerably unlikely
-exceptions).
-
-### Finding problematic bits of code using Node.js 8
-
-If you’re using Node.js ≥ 8.0.0 (which is recommended), Node.js exposes multiple options that help with finding the relevant pieces of code:
-
-- `--trace-warnings` will make Node.js show a stack trace for this warning and other warnings that are printed by Node.js.
-- `--trace-deprecation` does the same thing, but only for deprecation warnings.
-- `--pending-deprecation` will show more types of deprecation warnings. In particular, it will show the `Buffer()` deprecation warning, even on Node.js 8.
-
-You can set these flags using an environment variable:
-
-```console
-$ export NODE_OPTIONS='--trace-warnings --pending-deprecation'
-$ cat example.js
-'use strict';
-const foo = new Buffer('foo');
-$ node example.js
-(node:7147) [DEP0005] DeprecationWarning: The Buffer() and new Buffer() constructors are not recommended for use due to security and usability concerns. Please use the new Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() construction methods instead.
-    at showFlaggedDeprecation (buffer.js:127:13)
-    at new Buffer (buffer.js:148:3)
-    at Object.<anonymous> (/path/to/example.js:2:13)
-    [... more stack trace lines ...]
-```
-
-### Finding problematic bits of code using linters
-
-Eslint rules [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor)
-or
-[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md)
-also find calls to deprecated `Buffer()` API. Those rules are included in some pre-sets.
-
-There is a drawback, though, that it doesn't always
-[work correctly](https://github.com/chalker/safer-buffer#why-not-safe-buffer) when `Buffer` is
-overriden e.g. with a polyfill, so recommended is a combination of this and some other method
-described above.
-
-<a id="variant-1"></a>
-## Variant 1: Drop support for Node.js ≤ 4.4.x and 5.0.0 — 5.9.x.
-
-This is the recommended solution nowadays that would imply only minimal overhead.
-
-The Node.js 5.x release line has been unsupported since July 2016, and the Node.js 4.x release line reaches its End of Life in April 2018 (→ [Schedule](https://github.com/nodejs/Release#release-schedule)). This means that these versions of Node.js will *not* receive any updates, even in case of security issues, so using these release lines should be avoided, if at all possible.
-
-What you would do in this case is to convert all `new Buffer()` or `Buffer()` calls to use `Buffer.alloc()` or `Buffer.from()`, in the following way:
-
-- For `new Buffer(number)`, replace it with `Buffer.alloc(number)`.
-- For `new Buffer(string)` (or `new Buffer(string, encoding)`), replace it with `Buffer.from(string)` (or `Buffer.from(string, encoding)`).
-- For all other combinations of arguments (these are much rarer), also replace `new Buffer(...arguments)` with `Buffer.from(...arguments)`.
-
-Note that `Buffer.alloc()` is also _faster_ on the current Node.js versions than
-`new Buffer(size).fill(0)`, which is what you would otherwise need to ensure zero-filling.
-
-Enabling eslint rule [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor)
-or
-[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md)
-is recommended to avoid accidential unsafe Buffer API usage.
-
-There is also a [JSCodeshift codemod](https://github.com/joyeecheung/node-dep-codemod#dep005)
-for automatically migrating Buffer constructors to `Buffer.alloc()` or `Buffer.from()`.
-Note that it currently only works with cases where the arguments are literals or where the
-constructor is invoked with two arguments.
-
-_If you currently support those older Node.js versions and dropping them would be a semver-major change
-for you, or if you support older branches of your packages, consider using [Variant 2](#variant-2)
-or [Variant 3](#variant-3) on older branches, so people using those older branches will also receive
-the fix. That way, you will eradicate potential issues caused by unguarded Buffer API usage and
-your users will not observe a runtime deprecation warning when running your code on Node.js 10._
-
-<a id="variant-2"></a>
-## Variant 2: Use a polyfill
-
-Utilize [safer-buffer](https://www.npmjs.com/package/safer-buffer) as a polyfill to support older
-Node.js versions.
-
-You would take exacly the same steps as in [Variant 1](#variant-1), but with a polyfill
-`const Buffer = require('safer-buffer').Buffer` in all files where you use the new `Buffer` api.
-
-Make sure that you do not use old `new Buffer` API — in any files where the line above is added,
-using old `new Buffer()` API will _throw_. It will be easy to notice that in CI, though.
-
-Alternatively, you could use [buffer-from](https://www.npmjs.com/package/buffer-from) and/or
-[buffer-alloc](https://www.npmjs.com/package/buffer-alloc) [ponyfills](https://ponyfill.com/) —
-those are great, the only downsides being 4 deps in the tree and slightly more code changes to
-migrate off them (as you would be using e.g. `Buffer.from` under a different name). If you need only
-`Buffer.from` polyfilled — `buffer-from` alone which comes with no extra dependencies.
-
-_Alternatively, you could use [safe-buffer](https://www.npmjs.com/package/safe-buffer) — it also
-provides a polyfill, but takes a different approach which has
-[it's drawbacks](https://github.com/chalker/safer-buffer#why-not-safe-buffer). It will allow you
-to also use the older `new Buffer()` API in your code, though — but that's arguably a benefit, as
-it is problematic, can cause issues in your code, and will start emitting runtime deprecation
-warnings starting with Node.js 10._
-
-Note that in either case, it is important that you also remove all calls to the old Buffer
-API manually — just throwing in `safe-buffer` doesn't fix the problem by itself, it just provides
-a polyfill for the new API. I have seen people doing that mistake.
-
-Enabling eslint rule [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor)
-or
-[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md)
-is recommended.
-
-_Don't forget to drop the polyfill usage once you drop support for Node.js < 4.5.0._
-
-<a id="variant-3"></a>
-## Variant 3 — manual detection, with safeguards
-
-This is useful if you create Buffer instances in only a few places (e.g. one), or you have your own
-wrapper around them.
-
-### Buffer(0)
-
-This special case for creating empty buffers can be safely replaced with `Buffer.concat([])`, which
-returns the same result all the way down to Node.js 0.8.x.
-
-### Buffer(notNumber)
-
-Before:
-
-```js
-var buf = new Buffer(notNumber, encoding);
-```
-
-After:
-
-```js
-var buf;
-if (Buffer.from && Buffer.from !== Uint8Array.from) {
-  buf = Buffer.from(notNumber, encoding);
-} else {
-  if (typeof notNumber === 'number')
-    throw new Error('The "size" argument must be of type number.');
-  buf = new Buffer(notNumber, encoding);
-}
-```
-
-`encoding` is optional.
-
-Note that the `typeof notNumber` before `new Buffer` is required (for cases when `notNumber` argument is not
-hard-coded) and _is not caused by the deprecation of Buffer constructor_ — it's exactly _why_ the
-Buffer constructor is deprecated. Ecosystem packages lacking this type-check caused numereous
-security issues — situations when unsanitized user input could end up in the `Buffer(arg)` create
-problems ranging from DoS to leaking sensitive information to the attacker from the process memory.
-
-When `notNumber` argument is hardcoded (e.g. literal `"abc"` or `[0,1,2]`), the `typeof` check can
-be omitted.
-
-Also note that using TypeScript does not fix this problem for you — when libs written in
-`TypeScript` are used from JS, or when user input ends up there — it behaves exactly as pure JS, as
-all type checks are translation-time only and are not present in the actual JS code which TS
-compiles to.
-
-### Buffer(number)
-
-For Node.js 0.10.x (and below) support:
-
-```js
-var buf;
-if (Buffer.alloc) {
-  buf = Buffer.alloc(number);
-} else {
-  buf = new Buffer(number);
-  buf.fill(0);
-}
-```
-
-Otherwise (Node.js ≥ 0.12.x):
-
-```js
-const buf = Buffer.alloc ? Buffer.alloc(number) : new Buffer(number).fill(0);
-```
-
-## Regarding Buffer.allocUnsafe
-
-Be extra cautious when using `Buffer.allocUnsafe`:
- * Don't use it if you don't have a good reason to
-   * e.g. you probably won't ever see a performance difference for small buffers, in fact, those
-     might be even faster with `Buffer.alloc()`,
-   * if your code is not in the hot code path — you also probably won't notice a difference,
-   * keep in mind that zero-filling minimizes the potential risks.
- * If you use it, make sure that you never return the buffer in a partially-filled state,
-   * if you are writing to it sequentially — always truncate it to the actuall written length
-
-Errors in handling buffers allocated with `Buffer.allocUnsafe` could result in various issues,
-ranged from undefined behaviour of your code to sensitive data (user input, passwords, certs)
-leaking to the remote attacker.
-
-_Note that the same applies to `new Buffer` usage without zero-filling, depending on the Node.js
-version (and lacking type checks also adds DoS to the list of potential problems)._

-## FAQ
-
-<a id="design-flaws"></a>
-### What is wrong with the `Buffer` constructor?
-
-The `Buffer` constructor could be used to create a buffer in many different ways:
-
-- `new Buffer(42)` creates a `Buffer` of 42 bytes. Before Node.js 8, this buffer contained
-  *arbitrary memory* for performance reasons, which could include anything ranging from
-  program source code to passwords and encryption keys.
-- `new Buffer('abc')` creates a `Buffer` that contains the UTF-8-encoded version of
-  the string `'abc'`. A second argument could specify another encoding: For example,
-  `new Buffer(string, 'base64')` could be used to convert a Base64 string into the original
-  sequence of bytes that it represents.
-- There are several other combinations of arguments.
-
-This meant that, in code like `var buffer = new Buffer(foo);`, *it is not possible to tell
-what exactly the contents of the generated buffer are* without knowing the type of `foo`.
-
-Sometimes, the value of `foo` comes from an external source. For example, this function
-could be exposed as a service on a web server, converting a UTF-8 string into its Base64 form:
-
-```
-function stringToBase64(req, res) {
-  // The request body should have the format of `{ string: 'foobar' }`
-  const rawBytes = new Buffer(req.body.string)
-  const encoded = rawBytes.toString('base64')
-  res.end({ encoded: encoded })
-}
-```
-
-Note that this code does *not* validate the type of `req.body.string`:
-
-- `req.body.string` is expected to be a string. If this is the case, all goes well.
-- `req.body.string` is controlled by the client that sends the request.
-- If `req.body.string` is the *number* `50`, the `rawBytes` would be 50 bytes:
-  - Before Node.js 8, the content would be uninitialized
-  - After Node.js 8, the content would be `50` bytes with the value `0`
-
-Because of the missing type check, an attacker could intentionally send a number
-as part of the request. Using this, they can either:
-
-- Read uninitialized memory. This **will** leak passwords, encryption keys and other
-  kinds of sensitive information. (Information leak)
-- Force the program to allocate a large amount of memory. For example, when specifying
-  `500000000` as the input value, each request will allocate 500MB of memory.
-  This can be used to either exhaust the memory available of a program completely
-  and make it crash, or slow it down significantly. (Denial of Service)
-
-Both of these scenarios are considered serious security issues in a real-world
-web server context.
-
-when using `Buffer.from(req.body.string)` instead, passing a number will always
-throw an exception instead, giving a controlled behaviour that can always be
-handled by the program.
-
-<a id="ecosystem-usage"></a>
-### The `Buffer()` constructor has been deprecated for a while. Is this really an issue?
-
-Surveys of code in the `npm` ecosystem have shown that the `Buffer()` constructor is still
-widely used. This includes new code, and overall usage of such code has actually been
-*increasing*.

-Modern Buffer API polyfill without footguns, working on Node.js from 0.8 to current.
-
-## How to use?
-
-First, port all `Buffer()` and `new Buffer()` calls to `Buffer.alloc()` and `Buffer.from()` API.
-
-Then, to achieve compatibility with outdated Node.js versions (`<4.5.0` and 5.x `<5.9.0`), use
-`const Buffer = require('safer-buffer').Buffer` in all files where you make calls to the new
-Buffer API. _Use `var` instead of `const` if you need that for your Node.js version range support._
-
-Also, see the
-[porting Buffer](https://github.com/ChALkeR/safer-buffer/blob/master/Porting-Buffer.md) guide.
-
-## Do I need it?
-
-Hopefully, not — dropping support for outdated Node.js versions should be fine nowdays, and that
-is the recommended path forward. You _do_ need to port to the `Buffer.alloc()` and `Buffer.from()`
-though.
-
-See the [porting guide](https://github.com/ChALkeR/safer-buffer/blob/master/Porting-Buffer.md)
-for a better description.
-
-## Why not [safe-buffer](https://npmjs.com/safe-buffer)?
-
-_In short: while `safe-buffer` serves as a polyfill for the new API, it allows old API usage and
-itself contains footguns._
-
-`safe-buffer` could be used safely to get the new API while still keeping support for older
-Node.js versions (like this module), but while analyzing ecosystem usage of the old Buffer API
-I found out that `safe-buffer` is itself causing problems in some cases.
-
-For example, consider the following snippet:
-
-```console
-$ cat example.unsafe.js
-console.log(Buffer(20))
-$ ./node-v6.13.0-linux-x64/bin/node example.unsafe.js
-<Buffer 0a 00 00 00 00 00 00 00 28 13 de 02 00 00 00 00 05 00 00 00>
-$ standard example.unsafe.js
-standard: Use JavaScript Standard Style (https://standardjs.com)
-  /home/chalker/repo/safer-buffer/example.unsafe.js:2:13: 'Buffer()' was deprecated since v6. Use 'Buffer.alloc()' or 'Buffer.from()' (use 'https://www.npmjs.com/package/safe-buffer' for '<4.5.0') instead.
-```
-
-This is allocates and writes to console an uninitialized chunk of memory.
-[standard](https://www.npmjs.com/package/standard) linter (among others) catch that and warn people
-to avoid using unsafe API.
-
-Let's now throw in `safe-buffer`!
-
-```console
-$ cat example.safe-buffer.js
-const Buffer = require('safe-buffer').Buffer
-console.log(Buffer(20))
-$ standard example.safe-buffer.js
-$ ./node-v6.13.0-linux-x64/bin/node example.safe-buffer.js
-<Buffer 08 00 00 00 00 00 00 00 28 58 01 82 fe 7f 00 00 00 00 00 00>
-```
-
-See the problem? Adding in `safe-buffer` _magically removes the lint warning_, but the behavior
-remains identiсal to what we had before, and when launched on Node.js 6.x LTS — this dumps out
-chunks of uninitialized memory.
-_And this code will still emit runtime warnings on Node.js 10.x and above._
-
-That was done by design. I first considered changing `safe-buffer`, prohibiting old API usage or
-emitting warnings on it, but that significantly diverges from `safe-buffer` design. After some
-discussion, it was decided to move my approach into a separate package, and _this is that separate
-package_.
-
-This footgun is not imaginary — I observed top-downloaded packages doing that kind of thing,
-«fixing» the lint warning by blindly including `safe-buffer` without any actual changes.
-
-Also in some cases, even if the API _was_ migrated to use of safe Buffer API — a random pull request
-can bring unsafe Buffer API usage back to the codebase by adding new calls — and that could go
-unnoticed even if you have a linter prohibiting that (becase of the reason stated above), and even
-pass CI. _I also observed that being done in popular packages._
-
-Some examples:
- * [webdriverio](https://github.com/webdriverio/webdriverio/commit/05cbd3167c12e4930f09ef7cf93b127ba4effae4#diff-124380949022817b90b622871837d56cR31)
-   (a module with 548 759 downloads/month),
- * [websocket-stream](https://github.com/maxogden/websocket-stream/commit/c9312bd24d08271687d76da0fe3c83493871cf61)
-   (218 288 d/m, fix in [maxogden/websocket-stream#142](https://github.com/maxogden/websocket-stream/pull/142)),
- * [node-serialport](https://github.com/node-serialport/node-serialport/commit/e8d9d2b16c664224920ce1c895199b1ce2def48c)
-   (113 138 d/m, fix in [node-serialport/node-serialport#1510](https://github.com/node-serialport/node-serialport/pull/1510)),
- * [karma](https://github.com/karma-runner/karma/commit/3d94b8cf18c695104ca195334dc75ff054c74eec)
-   (3 973 193 d/m, fix in [karma-runner/karma#2947](https://github.com/karma-runner/karma/pull/2947)),
- * [spdy-transport](https://github.com/spdy-http2/spdy-transport/commit/5375ac33f4a62a4f65bcfc2827447d42a5dbe8b1)
-   (5 970 727 d/m, fix in [spdy-http2/spdy-transport#53](https://github.com/spdy-http2/spdy-transport/pull/53)).
- * And there are a lot more over the ecosystem.
-
-I filed a PR at
-[mysticatea/eslint-plugin-node#110](https://github.com/mysticatea/eslint-plugin-node/pull/110) to
-partially fix that (for cases when that lint rule is used), but it is a semver-major change for
-linter rules and presets, so it would take significant time for that to reach actual setups.
-_It also hasn't been released yet (2018-03-20)._
-
-Also, `safer-buffer` discourages the usage of `.allocUnsafe()`, which is often done by a mistake.
-It still supports it with an explicit concern barier, by placing it under
-`require('safer-buffer/dangereous')`.
-
-## But isn't throwing bad?
-
-Not really. It's an error that could be noticed and fixed early, instead of causing havoc later like
-unguarded `new Buffer()` calls that end up receiving user input can do.
-
-This package affects only the files where `var Buffer = require('safer-buffer').Buffer` was done, so
-it is really simple to keep track of things and make sure that you don't mix old API usage with that.
-Also, CI should hint anything that you might have missed.
-
-New commits, if tested, won't land new usage of unsafe Buffer API this way.
-_Node.js 10.x also deals with that by printing a runtime depecation warning._
-
-### Would it affect third-party modules?
-
-No, unless you explicitly do an awful thing like monkey-patching or overriding the built-in `Buffer`.
-Don't do that.
-
-### But I don't want throwing…
-
-That is also fine!
-
-Also, it could be better in some cases when you don't comprehensive enough test coverage.
-
-In that case — just don't override `Buffer` and use
-`var SaferBuffer = require('safer-buffer').Buffer` instead.
-
-That way, everything using `Buffer` natively would still work, but there would be two drawbacks:
-
-* `Buffer.from`/`Buffer.alloc` won't be polyfilled — use `SaferBuffer.from` and
-  `SaferBuffer.alloc` instead.
-* You are still open to accidentally using the insecure deprecated API — use a linter to catch that.
-
-Note that using a linter to catch accidential `Buffer` constructor usage in this case is strongly
-recommended. `Buffer` is not overriden in this usecase, so linters won't get confused.
-
-## «Without footguns»?
-
-Well, it is still possible to do _some_ things with `Buffer` API, e.g. accessing `.buffer` property
-on older versions and duping things from there. You shouldn't do that in your code, probabably.
-
-The intention is to remove the most significant footguns that affect lots of packages in the
-ecosystem, and to do it in the proper way.
-
-Also, this package doesn't protect against security issues affecting some Node.js versions, so for
-usage in your own production code, it is still recommended to update to a Node.js version
-[supported by upstream](https://github.com/nodejs/release#release-schedule).

-Send is a library for streaming files from the file system as a http response
-supporting partial responses (Ranges), conditional-GET negotiation (If-Match,
-If-Unmodified-Since, If-None-Match, If-Modified-Since), high test coverage,
-and granular events which may be leveraged to take appropriate actions in your
-application or framework.
-
-Looking to serve up entire folders mapped to URLs? Try [serve-static](https://www.npmjs.org/package/serve-static).
-
-## Installation
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```bash
-$ npm install send
-```
-
-## API
-
-```js
-var send = require('send')
-```
-
-### send(req, path, [options])
-
-Create a new `SendStream` for the given path to send to a `res`. The `req` is
-the Node.js HTTP request and the `path` is a urlencoded path to send (urlencoded,
-not the actual file-system path).
-
-#### Options
-
-##### acceptRanges
-
-Enable or disable accepting ranged requests, defaults to true.
-Disabling this will not send `Accept-Ranges` and ignore the contents
-of the `Range` request header.
-
-##### cacheControl
-
-Enable or disable setting `Cache-Control` response header, defaults to
-true. Disabling this will ignore the `immutable` and `maxAge` options.
-
-##### dotfiles
-
-Set how "dotfiles" are treated when encountered. A dotfile is a file
-or directory that begins with a dot ("."). Note this check is done on
-the path itself without checking if the path actually exists on the
-disk. If `root` is specified, only the dotfiles above the root are
-checked (i.e. the root itself can be within a dotfile when set
-to "deny").
-
-  - `'allow'` No special treatment for dotfiles.
-  - `'deny'` Send a 403 for any request for a dotfile.
-  - `'ignore'` Pretend like the dotfile does not exist and 404.
-
-The default value is _similar_ to `'ignore'`, with the exception that
-this default will not ignore the files within a directory that begins
-with a dot, for backward-compatibility.
-
-##### end
-
-Byte offset at which the stream ends, defaults to the length of the file
-minus 1. The end is inclusive in the stream, meaning `end: 3` will include
-the 4th byte in the stream.
-
-##### etag
-
-Enable or disable etag generation, defaults to true.
-
-##### extensions
-
-If a given file doesn't exist, try appending one of the given extensions,
-in the given order. By default, this is disabled (set to `false`). An
-example value that will serve extension-less HTML files: `['html', 'htm']`.
-This is skipped if the requested file already has an extension.
-
-##### immutable
-
-Enable or disable the `immutable` directive in the `Cache-Control` response
-header, defaults to `false`. If set to `true`, the `maxAge` option should
-also be specified to enable caching. The `immutable` directive will prevent
-supported clients from making conditional requests during the life of the
-`maxAge` option to check if the file has changed.
-
-##### index
-
-By default send supports "index.html" files, to disable this
-set `false` or to supply a new index pass a string or an array
-in preferred order.
-
-##### lastModified
-
-Enable or disable `Last-Modified` header, defaults to true. Uses the file
-system's last modified value.
-
-##### maxAge
-
-Provide a max-age in milliseconds for http caching, defaults to 0.
-This can also be a string accepted by the
-[ms](https://www.npmjs.org/package/ms#readme) module.
-
-##### root
-
-Serve files relative to `path`.
-
-##### start
-
-Byte offset at which the stream starts, defaults to 0. The start is inclusive,
-meaning `start: 2` will include the 3rd byte in the stream.
-
-#### Events
-
-The `SendStream` is an event emitter and will emit the following events:
-
-  - `error` an error occurred `(err)`
-  - `directory` a directory was requested `(res, path)`
-  - `file` a file was requested `(path, stat)`
-  - `headers` the headers are about to be set on a file `(res, path, stat)`
-  - `stream` file streaming has started `(stream)`
-  - `end` streaming has completed
-
-#### .pipe
-
-The `pipe` method is used to pipe the response into the Node.js HTTP response
-object, typically `send(req, path, options).pipe(res)`.
-
-## Error-handling
-
-By default when no `error` listeners are present an automatic response will be
-made, otherwise you have full control over the response, aka you may show a 5xx
-page etc.
-
-## Caching
-
-It does _not_ perform internal caching, you should use a reverse proxy cache
-such as Varnish for this, or those fancy things called CDNs. If your
-application is small enough that it would benefit from single-node memory
-caching, it's small enough that it does not need caching at all ;).
-
-## Debugging
-
-To enable `debug()` instrumentation output export __DEBUG__:
-
-```
-$ DEBUG=send node app
-```
-
-## Running tests
-
-```
-$ npm install
-$ npm test
-```
-
-## Examples
-
-### Serve a specific file
-
-This simple example will send a specific file to all requests.
-
-```js
-var http = require('http')
-var send = require('send')
-
-var server = http.createServer(function onRequest (req, res) {
-  send(req, '/path/to/index.html')
-    .pipe(res)
-})
-
-server.listen(3000)
-```
-
-### Serve all files from a directory
-
-This simple example will just serve up all the files in a
-given directory as the top-level. For example, a request
-`GET /foo.txt` will send back `/www/public/foo.txt`.
-
-```js
-var http = require('http')
-var parseUrl = require('parseurl')
-var send = require('send')
-
-var server = http.createServer(function onRequest (req, res) {
-  send(req, parseUrl(req).pathname, { root: '/www/public' })
-    .pipe(res)
-})
-
-server.listen(3000)
-```
-
-### Custom file types
-
-```js
-var extname = require('path').extname
-var http = require('http')
-var parseUrl = require('parseurl')
-var send = require('send')
-
-var server = http.createServer(function onRequest (req, res) {
-  send(req, parseUrl(req).pathname, { root: '/www/public' })
-    .on('headers', function (res, path) {
-      switch (extname(path)) {
-        case '.x-mt':
-        case '.x-mtt':
-          // custom type for these extensions
-          res.setHeader('Content-Type', 'application/x-my-type')
-          break
-      }
-    })
-    .pipe(res)
-})
-
-server.listen(3000)
-```
-
-### Custom directory index view
-
-This is an example of serving up a structure of directories with a
-custom function to render a listing of a directory.
-
-```js
-var http = require('http')
-var fs = require('fs')
-var parseUrl = require('parseurl')
-var send = require('send')
-
-// Transfer arbitrary files from within /www/example.com/public/*
-// with a custom handler for directory listing
-var server = http.createServer(function onRequest (req, res) {
-  send(req, parseUrl(req).pathname, { index: false, root: '/www/public' })
-    .once('directory', directory)
-    .pipe(res)
-})
-
-server.listen(3000)
-
-// Custom directory handler
-function directory (res, path) {
-  var stream = this
-
-  // redirect to trailing slash for consistent url
-  if (!stream.hasTrailingSlash()) {
-    return stream.redirect(path)
-  }
-
-  // get directory list
-  fs.readdir(path, function onReaddir (err, list) {
-    if (err) return stream.error(err)
-
-    // render an index for the directory
-    res.setHeader('Content-Type', 'text/plain; charset=UTF-8')
-    res.end(list.join('\n') + '\n')
-  })
-}
-```
-
-### Serving from a root directory with custom error-handling
-
-```js
-var http = require('http')
-var parseUrl = require('parseurl')
-var send = require('send')
-
-var server = http.createServer(function onRequest (req, res) {
-  // your custom error-handling logic:
-  function error (err) {
-    res.statusCode = err.status || 500
-    res.end(err.message)
-  }
-
-  // your custom headers
-  function headers (res, path, stat) {
-    // serve all files for download
-    res.setHeader('Content-Disposition', 'attachment')
-  }
-
-  // your custom directory handling logic:
-  function redirect () {
-    res.statusCode = 301
-    res.setHeader('Location', req.url + '/')
-    res.end('Redirecting to ' + req.url + '/')
-  }
-
-  // transfer arbitrary files from within
-  // /www/example.com/public/*
-  send(req, parseUrl(req).pathname, { root: '/www/public' })
-    .on('error', error)
-    .on('directory', redirect)
-    .on('headers', headers)
-    .pipe(res)
-})
-
-server.listen(3000)
-```

-
-## Install
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install serve-static
-```
-
-## API
-
-```js
-var serveStatic = require('serve-static')
-```
-
-### serveStatic(root, options)
-
-Create a new middleware function to serve files from within a given root
-directory. The file to serve will be determined by combining `req.url`
-with the provided root directory. When a file is not found, instead of
-sending a 404 response, this module will instead call `next()` to move on
-to the next middleware, allowing for stacking and fall-backs.
-
-#### Options
-
-##### acceptRanges
-
-Enable or disable accepting ranged requests, defaults to true.
-Disabling this will not send `Accept-Ranges` and ignore the contents
-of the `Range` request header.
-
-##### cacheControl
-
-Enable or disable setting `Cache-Control` response header, defaults to
-true. Disabling this will ignore the `immutable` and `maxAge` options.
-
-##### dotfiles
-
-Set how "dotfiles" are treated when encountered. A dotfile is a file
-or directory that begins with a dot ("."). Note this check is done on
-the path itself without checking if the path actually exists on the
-disk. If `root` is specified, only the dotfiles above the root are
-checked (i.e. the root itself can be within a dotfile when set
-to "deny").
-
-  - `'allow'` No special treatment for dotfiles.
-  - `'deny'` Deny a request for a dotfile and 403/`next()`.
-  - `'ignore'` Pretend like the dotfile does not exist and 404/`next()`.
-
-The default value is `'ignore'`.
-
-##### etag
-
-Enable or disable etag generation, defaults to true.
-
-##### extensions
-
-Set file extension fallbacks. When set, if a file is not found, the given
-extensions will be added to the file name and search for. The first that
-exists will be served. Example: `['html', 'htm']`.
-
-The default value is `false`.
-
-##### fallthrough
-
-Set the middleware to have client errors fall-through as just unhandled
-requests, otherwise forward a client error. The difference is that client
-errors like a bad request or a request to a non-existent file will cause
-this middleware to simply `next()` to your next middleware when this value
-is `true`. When this value is `false`, these errors (even 404s), will invoke
-`next(err)`.
-
-Typically `true` is desired such that multiple physical directories can be
-mapped to the same web address or for routes to fill in non-existent files.
-
-The value `false` can be used if this middleware is mounted at a path that
-is designed to be strictly a single file system directory, which allows for
-short-circuiting 404s for less overhead. This middleware will also reply to
-all methods.
-
-The default value is `true`.
-
-##### immutable
-
-Enable or disable the `immutable` directive in the `Cache-Control` response
-header, defaults to `false`. If set to `true`, the `maxAge` option should
-also be specified to enable caching. The `immutable` directive will prevent
-supported clients from making conditional requests during the life of the
-`maxAge` option to check if the file has changed.
-
-##### index
-
-By default this module will send "index.html" files in response to a request
-on a directory. To disable this set `false` or to supply a new index pass a
-string or an array in preferred order.
-
-##### lastModified
-
-Enable or disable `Last-Modified` header, defaults to true. Uses the file
-system's last modified value.
-
-##### maxAge
-
-Provide a max-age in milliseconds for http caching, defaults to 0. This
-can also be a string accepted by the [ms](https://www.npmjs.org/package/ms#readme)
-module.
-
-##### redirect
-
-Redirect to trailing "/" when the pathname is a dir. Defaults to `true`.
-
-##### setHeaders
-
-Function to set custom headers on response. Alterations to the headers need to
-occur synchronously. The function is called as `fn(res, path, stat)`, where
-the arguments are:
-
-  - `res` the response object
-  - `path` the file path that is being sent
-  - `stat` the stat object of the file that is being sent
-
-## Examples
-
-### Serve files with vanilla node.js http server
-
-```js
-var finalhandler = require('finalhandler')
-var http = require('http')
-var serveStatic = require('serve-static')
-
-// Serve up public/ftp folder
-var serve = serveStatic('public/ftp', { index: ['index.html', 'index.htm'] })
-
-// Create server
-var server = http.createServer(function onRequest (req, res) {
-  serve(req, res, finalhandler(req, res))
-})
-
-// Listen
-server.listen(3000)
-```
-
-### Serve all files as downloads
-
-```js
-var contentDisposition = require('content-disposition')
-var finalhandler = require('finalhandler')
-var http = require('http')
-var serveStatic = require('serve-static')
-
-// Serve up public/ftp folder
-var serve = serveStatic('public/ftp', {
-  index: false,
-  setHeaders: setHeaders
-})
-
-// Set header to force download
-function setHeaders (res, path) {
-  res.setHeader('Content-Disposition', contentDisposition(path))
-}
-
-// Create server
-var server = http.createServer(function onRequest (req, res) {
-  serve(req, res, finalhandler(req, res))
-})
-
-// Listen
-server.listen(3000)
-```
-
-### Serving using express
-
-#### Simple
-
-This is a simple example of using Express.
-
-```js
-var express = require('express')
-var serveStatic = require('serve-static')
-
-var app = express()
-
-app.use(serveStatic('public/ftp', { index: ['default.html', 'default.htm'] }))
-app.listen(3000)
-```
-
-#### Multiple roots
-
-This example shows a simple way to search through multiple directories.
-Files are searched for in `public-optimized/` first, then `public/` second
-as a fallback.
-
-```js
-var express = require('express')
-var path = require('path')
-var serveStatic = require('serve-static')
-
-var app = express()
-
-app.use(serveStatic(path.join(__dirname, 'public-optimized')))
-app.use(serveStatic(path.join(__dirname, 'public')))
-app.listen(3000)
-```
-
-#### Different settings for paths
-
-This example shows how to set a different max age depending on the served
-file. In this example, HTML files are not cached, while everything else
-is for 1 day.
-
-```js
-var express = require('express')
-var path = require('path')
-var serveStatic = require('serve-static')
-
-var app = express()
-
-app.use(serveStatic(path.join(__dirname, 'public'), {
-  maxAge: '1d',
-  setHeaders: setCustomCacheControl
-}))
-
-app.listen(3000)
-
-function setCustomCacheControl (res, file) {
-  if (path.extname(file) === '.html') {
-    // Custom Cache-Control for HTML files
-    res.setHeader('Cache-Control', 'public, max-age=0')
-  }
-}
-```

-
-A simple cross platform implementation to set the prototype of an instianted object.  Supports all modern browsers and at least back to IE8.
-
-## Usage:
-
-```
-$ npm install --save setprototypeof
-```
-
-```javascript
-var setPrototypeOf = require('setprototypeof')
-
-var obj = {}
-setPrototypeOf(obj, {
-  foo: function () {
-    return 'bar'
-  }
-})
-obj.foo() // bar
-```
-
-TypeScript is also supported:
-
-```typescript
-import setPrototypeOf from 'setprototypeof'
-```

-
-Store information about any JS value in a side channel, using a linked list.
-
-Warning: this implementation will leak memory until you `delete` the `key`.
-Use [`side-channel`](https://npmjs.com/side-channel) for the best available strategy.
-
-## Getting started
-
-```sh
-npm install --save side-channel-list
-```
-
-## Usage/Examples
-
-```js
-const assert = require('assert');
-const getSideChannelList = require('side-channel-list');
-
-const channel = getSideChannelList();
-
-const key = {};
-assert.equal(channel.has(key), false);
-assert.throws(() => channel.assert(key), TypeError);
-
-channel.set(key, 42);
-
-channel.assert(key); // does not throw
-assert.equal(channel.has(key), true);
-assert.equal(channel.get(key), 42);
-
-channel.delete(key);
-assert.equal(channel.has(key), false);
-assert.throws(() => channel.assert(key), TypeError);
-```
-
-## Tests
-
-Clone the repo, `npm install`, and run `npm test`

-
-Store information about any JS value in a side channel, using a Map.
-
-Warning: if the `key` is an object, this implementation will leak memory until you `delete` it.
-Use [`side-channel`](https://npmjs.com/side-channel) for the best available strategy.
-
-## Getting started
-
-```sh
-npm install --save side-channel-map
-```
-
-## Usage/Examples
-
-```js
-const assert = require('assert');
-const getSideChannelMap = require('side-channel-map');
-
-const channel = getSideChannelMap();
-
-const key = {};
-assert.equal(channel.has(key), false);
-assert.throws(() => channel.assert(key), TypeError);
-
-channel.set(key, 42);
-
-channel.assert(key); // does not throw
-assert.equal(channel.has(key), true);
-assert.equal(channel.get(key), 42);
-
-channel.delete(key);
-assert.equal(channel.has(key), false);
-assert.throws(() => channel.assert(key), TypeError);
-```
-
-## Tests
-
-Clone the repo, `npm install`, and run `npm test`

-
-Store information about any JS value in a side channel. Uses WeakMap if available.
-
-Warning: this implementation will leak memory until you `delete` the `key`.
-Use [`side-channel`](https://npmjs.com/side-channel) for the best available strategy.
-
-## Getting started
-
-```sh
-npm install --save side-channel-weakmap
-```
-
-## Usage/Examples
-
-```js
-const assert = require('assert');
-const getSideChannelList = require('side-channel-weakmap');
-
-const channel = getSideChannelList();
-
-const key = {};
-assert.equal(channel.has(key), false);
-assert.throws(() => channel.assert(key), TypeError);
-
-channel.set(key, 42);
-
-channel.assert(key); // does not throw
-assert.equal(channel.has(key), true);
-assert.equal(channel.get(key), 42);
-
-channel.delete(key);
-assert.equal(channel.has(key), false);
-assert.throws(() => channel.assert(key), TypeError);
-```
-
-## Tests
-
-Clone the repo, `npm install`, and run `npm test`

-
-Store information about any JS value in a side channel. Uses WeakMap if available.
-
-Warning: in an environment that lacks `WeakMap`, this implementation will leak memory until you `delete` the `key`.
-
-## Getting started
-
-```sh
-npm install --save side-channel
-```
-
-## Usage/Examples
-
-```js
-const assert = require('assert');
-const getSideChannel = require('side-channel');
-
-const channel = getSideChannel();
-
-const key = {};
-assert.equal(channel.has(key), false);
-assert.throws(() => channel.assert(key), TypeError);
-
-channel.set(key, 42);
-
-channel.assert(key); // does not throw
-assert.equal(channel.has(key), true);
-assert.equal(channel.get(key), 42);
-
-channel.delete(key);
-assert.equal(channel.has(key), false);
-assert.throws(() => channel.assert(key), TypeError);
-```
-
-## Tests
-
-Clone the repo, `npm install`, and run `npm test`

-HTTP status utility for node.
-
-This module provides a list of status codes and messages sourced from
-a few different projects:
-
-  * The [IANA Status Code Registry](https://www.iana.org/assignments/http-status-codes/http-status-codes.xhtml)
-  * The [Node.js project](https://nodejs.org/)
-  * The [NGINX project](https://www.nginx.com/)
-  * The [Apache HTTP Server project](https://httpd.apache.org/)
-
-## Installation
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install statuses
-```
-
-## API
-
-<!-- eslint-disable no-unused-vars -->
-
-```js
-var status = require('statuses')
-```
-
-### status(code)
-
-Returns the status message string for a known HTTP status code. The code
-may be a number or a string. An error is thrown for an unknown status code.
-
-<!-- eslint-disable no-undef -->
-
-```js
-status(403) // => 'Forbidden'
-status('403') // => 'Forbidden'
-status(306) // throws
-```
-
-### status(msg)
-
-Returns the numeric status code for a known HTTP status message. The message
-is case-insensitive. An error is thrown for an unknown status message.
-
-<!-- eslint-disable no-undef -->
-
-```js
-status('forbidden') // => 403
-status('Forbidden') // => 403
-status('foo') // throws
-```
-
-### status.codes
-
-Returns an array of all the status codes as `Integer`s.
-
-### status.code[msg]
-
-Returns the numeric status code for a known status message (in lower-case),
-otherwise `undefined`.
-
-<!-- eslint-disable no-undef, no-unused-expressions -->
-
-```js
-status['not found'] // => 404
-```
-
-### status.empty[code]
-
-Returns `true` if a status code expects an empty body.
-
-<!-- eslint-disable no-undef, no-unused-expressions -->
-
-```js
-status.empty[200] // => undefined
-status.empty[204] // => true
-status.empty[304] // => true
-```
-
-### status.message[code]
-
-Returns the string message for a known numeric status code, otherwise
-`undefined`. This object is the same format as the
-[Node.js http module `http.STATUS_CODES`](https://nodejs.org/dist/latest/docs/api/http.html#http_http_status_codes).
-
-<!-- eslint-disable no-undef, no-unused-expressions -->
-
-```js
-status.message[404] // => 'Not Found'
-```
-
-### status.redirect[code]
-
-Returns `true` if a status code is a valid redirect status.
-
-<!-- eslint-disable no-undef, no-unused-expressions -->
-
-```js
-status.redirect[200] // => undefined
-status.redirect[301] // => true
-```
-
-### status.retry[code]
-
-Returns `true` if you should retry the rest.
-
-<!-- eslint-disable no-undef, no-unused-expressions -->
-
-```js
-status.retry[501] // => undefined
-status.retry[503] // => true
-```

-> Convert a string of words to a JavaScript identifier
-
-## Install
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```bash
-$ npm install toidentifier
-```
-
-## Example
-
-```js
-var toIdentifier = require('toidentifier')
-
-console.log(toIdentifier('Bad Request'))
-// => "BadRequest"
-```
-
-## API
-
-This CommonJS module exports a single default function: `toIdentifier`.
-
-### toIdentifier(string)
-
-Given a string as the argument, it will be transformed according to
-the following rules and the new string will be returned:
-
-1. Split into words separated by space characters (`0x20`).
-2. Upper case the first character of each word.
-3. Join the words together with no separator.
-4. Remove all non-word (`[0-9a-z_]`) characters.

-Infer the content-type of a request.
-
-## Install
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install type-is
-```
-
-## API
-
-```js
-var http = require('http')
-var typeis = require('type-is')
-
-http.createServer(function (req, res) {
-  var istext = typeis(req, ['text/*'])
-  res.end('you ' + (istext ? 'sent' : 'did not send') + ' me text')
-})
-```
-
-### typeis(request, types)
-
-Checks if the `request` is one of the `types`. If the request has no body,
-even if there is a `Content-Type` header, then `null` is returned. If the
-`Content-Type` header is invalid or does not matches any of the `types`, then
-`false` is returned. Otherwise, a string of the type that matched is returned.
-
-The `request` argument is expected to be a Node.js HTTP request. The `types`
-argument is an array of type strings.
-
-Each type in the `types` array can be one of the following:
-
-- A file extension name such as `json`. This name will be returned if matched.
-- A mime type such as `application/json`.
-- A mime type with a wildcard such as `*/*` or `*/json` or `application/*`.
-  The full mime type will be returned if matched.
-- A suffix such as `+json`. This can be combined with a wildcard such as
-  `*/vnd+json` or `application/*+json`. The full mime type will be returned
-  if matched.
-
-Some examples to illustrate the inputs and returned value:
-
-```js
-// req.headers.content-type = 'application/json'
-
-typeis(req, ['json']) // => 'json'
-typeis(req, ['html', 'json']) // => 'json'
-typeis(req, ['application/*']) // => 'application/json'
-typeis(req, ['application/json']) // => 'application/json'
-
-typeis(req, ['html']) // => false
-```
-
-### typeis.hasBody(request)
-
-Returns a Boolean if the given `request` has a body, regardless of the
-`Content-Type` header.
-
-Having a body has no relation to how large the body is (it may be 0 bytes).
-This is similar to how file existence works. If a body does exist, then this
-indicates that there is data to read from the Node.js request stream.
-
-```js
-if (typeis.hasBody(req)) {
-  // read the body, since there is one
-
-  req.on('data', function (chunk) {
-    // ...
-  })
-}
-```
-
-### typeis.is(mediaType, types)
-
-Checks if the `mediaType` is one of the `types`. If the `mediaType` is invalid
-or does not matches any of the `types`, then `false` is returned. Otherwise, a
-string of the type that matched is returned.
-
-The `mediaType` argument is expected to be a
-[media type](https://tools.ietf.org/html/rfc6838) string. The `types` argument
-is an array of type strings.
-
-Each type in the `types` array can be one of the following:
-
-- A file extension name such as `json`. This name will be returned if matched.
-- A mime type such as `application/json`.
-- A mime type with a wildcard such as `*/*` or `*/json` or `application/*`.
-  The full mime type will be returned if matched.
-- A suffix such as `+json`. This can be combined with a wildcard such as
-  `*/vnd+json` or `application/*+json`. The full mime type will be returned
-  if matched.
-
-Some examples to illustrate the inputs and returned value:
-
-```js
-var mediaType = 'application/json'
-
-typeis.is(mediaType, ['json']) // => 'json'
-typeis.is(mediaType, ['html', 'json']) // => 'json'
-typeis.is(mediaType, ['application/*']) // => 'application/json'
-typeis.is(mediaType, ['application/json']) // => 'application/json'
-
-typeis.is(mediaType, ['html']) // => false
-```
-
-### typeis.match(expected, actual)
-
-Match the type string `expected` with `actual`, taking in to account wildcards.
-A wildcard can only be in the type of the subtype part of a media type and only
-in the `expected` value (as `actual` should be the real media type to match). A
-suffix can still be included even with a wildcard subtype. If an input is
-malformed, `false` will be returned.
-
-```js
-typeis.match('text/html', 'text/html') // => true
-typeis.match('*/html', 'text/html') // => true
-typeis.match('text/*', 'text/html') // => true
-typeis.match('*/*', 'text/html') // => true
-typeis.match('*/*+json', 'application/x-custom+json') // => true
-```
-
-### typeis.normalize(type)
-
-Normalize a `type` string. This works by performing the following:
-
-- If the `type` is not a string, `false` is returned.
-- If the string starts with `+` (so it is a `+suffix` shorthand like `+json`),
-  then it is expanded to contain the complete wildcard notation of `*/*+suffix`.
-- If the string contains a `/`, then it is returned as the type.
-- Else the string is assumed to be a file extension and the mapped media type is
-  returned, or `false` is there is no mapping.
-
-This includes two special mappings:
-
-- `'multipart'` -> `'multipart/*'`
-- `'urlencoded'` -> `'application/x-www-form-urlencoded'`
-
-## Examples
-
-### Example body parser
-
-```js
-var express = require('express')
-var typeis = require('type-is')
-
-var app = express()
-
-app.use(function bodyParser (req, res, next) {
-  if (!typeis.hasBody(req)) {
-    return next()
-  }
-
-  switch (typeis(req, ['urlencoded', 'json', 'multipart'])) {
-    case 'urlencoded':
-      // parse urlencoded body
-      throw new Error('implement urlencoded body parsing')
-    case 'json':
-      // parse json body
-      throw new Error('implement json body parsing')
-    case 'multipart':
-      // parse multipart body
-      throw new Error('implement multipart body parsing')
-    default:
-      // 415 error code
-      res.statusCode = 415
-      res.end()
-      break
-  }
-})
-```

-
-Manipulate the HTTP Vary header
-
-## Installation
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally): 
-
-```sh
-$ npm install vary
-```
-
-## API
-
-<!-- eslint-disable no-unused-vars -->
-
-```js
-var vary = require('vary')
-```
-
-### vary(res, field)
-
-Adds the given header `field` to the `Vary` response header of `res`.
-This can be a string of a single field, a string of a valid `Vary`
-header, or an array of multiple fields.
-
-This will append the header if not already listed, otherwise leaves
-it listed in the current location.
-
-<!-- eslint-disable no-undef -->
-
-```js
-// Append "Origin" to the Vary header of the response
-vary(res, 'Origin')
-```
-
-### vary.append(header, field)
-
-Adds the given header `field` to the `Vary` response header string `header`.
-This can be a string of a single field, a string of a valid `Vary` header,
-or an array of multiple fields.
-
-This will append the header if not already listed, otherwise leaves
-it listed in the current location. The new header string is returned.
-
-<!-- eslint-disable no-undef -->
-
-```js
-// Get header string appending "Origin" to "Accept, User-Agent"
-vary.append('Accept, User-Agent', 'Origin')
-```
-
-## Examples
-
-### Updating the Vary header when content is based on it
-
-```js
-var http = require('http')
-var vary = require('vary')
-
-http.createServer(function onRequest (req, res) {
-  // about to user-agent sniff
-  vary(res, 'User-Agent')
-
-  var ua = req.headers['user-agent'] || ''
-  var isMobile = /mobi|android|touch|mini/i.test(ua)
-
-  // serve site, depending on isMobile
-  res.setHeader('Content-Type', 'text/html')
-  res.end('You are (probably) ' + (isMobile ? '' : 'not ') + 'a mobile user')
-})
-```
-
-## Testing
-
-```sh
-$ npm test
-```
