Along the tour (PLN-02, PLN-03): the list shows one line per place (its icon, name and distance from the route) and scrolls past ten. A place picked in the list or on the map opens its card over the map, where the other cards of the planner sit, with what the source says and the way to take it in as a stop. What taking it in did is one line in the list. The intro, the theme line and the out-of-date note are gone: the themes say what they look for on hover, and the search button says when to search again. A stop taken in from there keeps the kind of place it was found as (migration 045400, poi_category, read back only where the contract knows the kind) and its number carries that kind's icon at the corner, as a via ferrata's end does. City walks (CW-02, CW-03, CW-10): a stay nobody entered says nothing. While no stay is entered at all the walk is planned as its walking time, with no "unknown" and no "at least". A must-see rings its number, an optional stop has a dashed ring, a protected one a shield at the corner; only the stay stays under the name, below the coordinates.
@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.
