- server: allow distance_unit as an admin default (+ value validation) so the Admin "Default User Settings" toggle persists instead of returning 400 - i18n: add settings.distance to all 20 locales and translate the labels through t() instead of hardcoding "Distance" - route legs: include the unit in the OSRM cache key and recompute on a unit switch, so map and sidebar distances refresh and never mix units - keep wind speed tied to the temperature unit — a distance setting must not silently flip existing Fahrenheit users from mph to km/h - restore the sub-1km metres reading for metric, convert GPX elevation to feet for imperial, and format distances with a '.' decimal in every locale - add units.test.ts
@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.
