A petrol station and a campsite both came back as the same nameless grey dot, because the road categories only existed on the server: the map falls back to grey for a category it does not know. They now sit in the client's category table too — with the pump, the bolt, the parking sign and the tent, in their own colours — which both map renderers and the popup read from the same place. They stay out of the explore pill's own list on purpose: that pill offers what a city visit needs, and while road trip mode is on it is not on screen anyway. The search also stayed quiet when only some boxes failed, which reads as "no fuel on this stretch" when the truth is that nobody looked. A partial failure now says how many stretches went unanswered.
@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.
