vi called the Tracks filter "songs", sv the pending status "commuting", nl the open-now pill "opening hours", and tr showed "its plan" on the Plan tab and "being suspended" for pending. The road trip strings added in August had lost their accents in eight languages (Arrive and Leave, the stay buttons, the whole day and halfway filters, the avoidance options), uk had a Latin i in "halfway", hu and tr called No tolls "free of charge", and az put an en dash between the two ends. sv and vi said "I owe" for I'm owed and You're owed, sv had "Namnn" as the table's Name, and th said "split equally" for Split matches total. The climate hint of the day details and the Unfinished tooltip in Costs lose their dash in every language.
@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.
