TREK/shared
Maurice 2becbd17bc fix(book): the designed book paces its bursts, lists and maps the way the design asks
A burst of four or more photos within a quarter of an hour becomes one grid,
no beat runs three times in a row, and an entry's pros and cons go into the
room under its words on the opener, the panorama or the quiet page, with a
note when they find none. A chapter map is the map of the chapter's trip, and
entries on no trip are named in the notes. The sorts compare by code unit, the
summary metrics and the page lookups exist once, and a flag or country mark
asked for by its own code is labelled with that country.

@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.
