Maurice d5d2d6b25e feat(tours): city walks in the contract and on the server (CW-01, CW-02, CW-03, CW-09, CW-10)
A tour can be a city walk. Its points are stations that keep a key across
saves, a name, a stay (0 for a point passed through, empty when unknown), an
importance and a protection; the visits of a walk's stations are kept per day
assignment, so another day or a copy starts with nothing visited. A station
that is gone takes its visits with it. An assistant reads how far a walk got
on a day, what is open and which times are known.

@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): via paths in server/tsconfig.json.
  • Client (vite): via resolve.alias in client/vite.config.ts (+ paths for 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.
