Pinning an afternoon stop sorted that one and left the hotel it was booked around sitting behind it. The day's auto-sort reads each stop's own hour, and a booked night has none: nobody types a time into a hotel row, they type a check-in, and that lives on the booking. It counts now, so the night moves with everything else instead of staying where it was dropped. The assignments e2e builds its own tables and had neither the accommodation column nor day_accommodations, so every create in that file 500'd as soon as the insert learned to carry a booking id. Both are there now. And the shared lint, which is stricter than the other two and which I had not run: three leftovers from taking the check-out out of the chain, none of them used any more.
@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.
