Book page setup and element geometry were unbounded numbers, so a shared book could be saved with zero, negative or astronomical dimensions and every consumer downstream - the canvas, the PDF export - had to cope. Day-note caps had drifted from the limits their own doc comment states, and icon had none. On the test side: the path filter meant a PR touching only the root lockfile ran no jobs at all, which is exactly the change class most likely to break a native binding; the canAccessTrip mock is hand-copied into 72 files and had already drifted from the real query; the path-traversal test asserted only status !== 200, so a 500 from a broken guard passed it; and one unit test shelled out to a real kitinerary binary if the host happened to have one.
@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.
