- Prisma: Zone (postal-code list or radius), Rate (zone- or distance-band
keyed), GeocodeCache (permanent address->lat/lng cache per
IMPLEMENTATION_PLAN.md §9), Location.shopifyLocationId (maps to
Shopify's own Location resource for inventory checks), Booking.zoneId
(needed for per-zone delivery-density counts, not just per-location).
- app/lib/geo.ts: pure haversine distance + postal-code matching, unit
tested against known city-to-city distances.
- app/services/zones.server.ts: geocoding (Google Maps Geocoding API,
cached — never re-geocodes the same address twice), zone eligibility,
nearest-location auto-assignment ranked by distance, delivery-density
threshold checks (a sparse zone doesn't unlock until minOrders bookings
have already routed through it), and inventory-based location exclusion
via Shopify's InventoryLevel API (locations without a mapped
shopifyLocationId are left in rather than false-negative excluded).
- app/services/rates.server.ts: pure rate resolution by zone or distance
band, cheapest-match-wins when bands overlap.
- apps.scheduling.availability.tsx: LOCAL_DELIVERY requests with a
postalCode/address now auto-assign to the nearest eligible,
density-qualified zone/location instead of the shop's default location;
response includes the matched rate. Also fixed a real gap left over from
Phase 4: this route never actually read Booking counts into
getAvailability's `consumed` map, so capacity always showed as fully
available regardless of existing bookings — now it does.
- extensions/datetime-widget: LOCAL_DELIVERY now asks for a postal code
before showing dates; PICKUP shows a Google Maps pin for the location
(both gated on an optional Maps API key — a block setting in the theme
editor, since it needs to be public/client-side, not an app secret);
confirmation display and cart attributes (dd_zone_id, dd_rate_label)
carry the resolved zone/rate through to checkout.
- extensions/delivery-customization: now appends the resolved rate to the
relabeled delivery option ("Local delivery — Aug 25 ($5.99)") when one's
configured — real Cart Transform-based fee *charging* stays deferred to
v2 per IMPLEMENTATION_PLAN.md §5.4, this is display-only.
- Admin: /app/zones and /app/rates (Polaris CRUD, mirroring Phase 1's
patterns), plus shopifyLocationId and auto-geocode-on-save added to the
location edit form.
Fixed one real bug caught only by `npm run build` (not tsc/vitest, which
both passed clean): app.rates._index.tsx's component called
formatPriceLabel from rates.server.ts, and Remix correctly refuses to
bundle anything imported from a .server.ts path for the client. Moved the
pure (no I/O, no Prisma) formatter to app/lib/currency.ts.
Verified: lint, typecheck, 86 unit tests (+21 new: geo, zones, rates,
delivery-customization's rate-label case with a real WASM fixture run),
16 integration tests against live Postgres (+8 new: geocode caching,
postal/radius zone matching, nearest-first ranking, density thresholds),
both builds, and a live script exercising the full
zone-match -> density-check -> rate-resolve -> availability pipeline
together against the Postgres container.

The user linked the app to a real Partner org and hit two live errors
running `shopify app dev`, which is exactly the verification the earlier
hand-scaffolded Functions couldn't get in this environment. Root-caused and
fixed both, then went further: regenerated both Functions from scratch via
`shopify app generate extension` (now possible — the user's session had
authenticated) instead of patching the guesses.
What broke and why:
- `shopify app config link` pulled a fresh app's (empty) remote config and
overwrote shopify.app.toml, dropping the webhook subscriptions and
app_proxy block — restored both, keeping the real client_id/name/scopes
the CLI set.
- `[extensions.build.watch]` as a nested table was invalid TOML for this
field — it's a plain `watch = [...]` array directly under
`[extensions.build]`.
- The real failure ("doesn't have a build command or it's empty") turned
out to be a red herring pointing at a stale filename
(shopify.function.extension.toml, not the current shopify.extension.toml)
— the actual problem was that `@shopify/shopify_function` was never
installed for these extensions (confirmed: no node_modules), because
hand-writing package.json doesn't run the install step
`shopify app generate extension` does automatically.
Rather than keep guessing at the toolchain, regenerated both Functions for
real:
- `shopify app generate extension --template=cart_checkout_validation` and
`--template=delivery_customization` (--flavor=vanilla-js), which produces
a working vite/vitest-based build+test setup, real
`@shopify/shopify-function-test-helpers` fixture testing (builds actual
WASM and runs it via function-runner), and a generated GraphQL type file
per extension.
- This surfaced several concrete corrections to what was hand-written
before: the real target names are `cart.validations.generate.run` and
`cart.delivery-options.transform.run` (not `purchase.validation.run` /
`purchase.delivery-customization.run`), current api_version is 2026-07
(not 2025-01), the validation output wraps errors in
`operations: [{ validationAdd: { errors } }]` with a plain `message`
field (not top-level `errors` with `localizedMessage`), and the rename
operation is `deliveryOptionRename: { deliveryOptionHandle, title }` (not
`rename: { deliveryOptionHandle, title }`).
- Rewrote each extension's `.graphql` input query to request our actual
dd_* cart attributes (plus delivery option handles for the rename case),
regenerated types via `npm run typegen` in each, and ported the pure
evaluate.js decision logic (same exported function names/behavior as
before, now proven correct against the live schema) into the adapter
file the generator expects.
- Replaced each extension's demo fixture with ones matching our real
logic; `npm test` inside each extension now compiles real WASM and runs
function-runner against them — this is strictly stronger verification
than the previous pure-JS-only unit tests (which are kept too, unchanged,
since the evaluate.js files kept the same interface).
Repo-wide wiring: extensions/*/generated and extensions/*/dist are not
committed (matches the CLI's own per-extension .gitignore) — added
`npm run typegen:functions` (runs automatically before `npm run typecheck`
via a pretypecheck hook) and `npm run test:functions`, both now also in CI.
Root `npm install` picked these two folders up as proper npm workspace
members (they already have their own package.json from generation).
Verified: lint, typecheck, all 52 unit tests, all 8 integration tests, both
extensions' real WASM/function-runner test suites (5 fixtures total), and
both `npm run build` / `npm run build:widget` all pass.
