"Add to Apple Wallet" on a booking in the iOS app turns it into a TREK pass: a boarding pass from and to for flights, trains, buses and boats, check-in and check-out for a stay, pickup and drop-off for a car, the time for anything else, with the confirmation code as a QR code. Wallet brings it up on the lock screen around its time and place: times carry the offset of the endpoint's zone (looked up from the coordinates where the endpoint has none), stays and restaurants their place's coordinates. The labels come from the booking forms' own strings, so nothing new to translate on the pass. Only liketrek holds the Pass Type ID certificate, so the server sends the pass's texts to the TREK services' signer (TREK_WALLET_PASS_URL, push.liketrek.com) once per tap; it stores nothing, and TREK_SERVICES=off turns it off with the other services. Texts are cleaned of links and shortened here, the answer must be a .pkpass within 512 KB, and a user gets 20 passes a minute. - New wallet-pass domain: GET /api/trips/:tripId/reservations/:id/wallet-pass behind the trip guard, the booking checked to belong to the trip; trip title and place come from the reservations domain (findPassContext) - MWalletButton in the transport and booking sheets, only where the app binary has the wallet feature; undated bookings and failures are told apart - TREK_WALLET_PASS_URL in .env.example, compose, Helm and the wiki
@trek/shared
Single source of truth for TREK's API contracts, expressed as Zod schemas and consumed by both the server (request validation + inferred DTO types) and the client (typed requests/responses).
This package is part of the incremental NestJS + React 19 migration (see the "Brownfield Rewrite" board). It is intentionally dormant until modules start importing it — adding it changes nothing for users.
Rules
- One folder per domain:
src/<domain>/<domain>.schema.ts(+.spec.ts). - Domain-agnostic building blocks live in
src/common/. - A route is only considered migrated once its contract lives here.
- Schemas are the source of truth; server DTOs and client types are inferred from them
(
z.infer<typeof schema>), never hand-duplicated.
Consumption (dev)
Both apps resolve @trek/shared to this package's TypeScript source:
- Server (
tsx): viapathsinserver/tsconfig.json. - Client (
vite): viaresolve.aliasinclient/vite.config.ts(+pathsfor the type-checker).
Production packaging (Docker / workspace wiring) is introduced in card F2, when the server first depends on this package at runtime. Until then prod builds are untouched.
Not yet here
The canonical error envelope is finalised in card F5 (it must match TREK's current Express error responses byte-for-byte), so it is deliberately not invented in F1.
