Taking a tour kept in a collection into a trip left the user guessing in two places when the tour had no line. The map box stayed an empty grey square that read as a broken map; it now says that there is no line yet, only the waypoints. Why "Line only" is dimmed was only in the tooltip of a disabled button, which never shows on hover, focus or touch; the reason now stands under the two choices, and a disabled tile sits in a span so its tooltip can show as well. A successful take-over said the same sentence twice, as a toast and as the dialog's last word with "Open trip". The toast is gone. The collection strings move out of tours.ts into a tourCollection.ts per locale, keeping their keys, so no locale's tours file grows past the 1000-line limit. The tours locale spec now holds both files to their own counts.
@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.
