A ride sends its full line with heights and every horse route section's own line besides, about fifty bytes a point, so a ride along a few thousand points of bridleway hit the API's 100kb body ceiling and the save failed with a 413. Creating and editing a tour are now measured against TOUR_WRITE_MAX_BYTES (2 MB), like the book and list file routes; every other route, the tour copy among them, keeps 100kb. The horse routes kept in memory are now bounded by section points as well as by count (64 answers, 500k points), so panning a dense map can no longer grow the server by hundreds of megabytes. A search that found no connection can be asked again on the view whose routes are shown, and a ride with a recorded time shows the horseshoe beside its riding time instead of footprints.
@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.
