Settings > General > Language & region gets "Week starts on" (Monday, Sunday or Saturday), and Admin > User Defaults a default for everyone who has not picked one. Monday stays the built-in value, so nothing changes for anyone who leaves it alone. Both calendar implementations follow it: CustomDatePicker, used by trip dates, bookings, costs, to-dos and the admin school holidays on desktop and phone, and the journey date picker, whose weekday headers were hardcoded English and now speak the app language. The grid math and the header row live in one helper (utils/calendarWeek.ts). The day names on the options come from Intl, so only the label and a hint needed translating. Vacay keeps its own per-plan week start. The value is validated like the other regional settings: VALID_VALUES for admin defaults, the display-settings MCP tool, and the managed key list. Addresses discussion #2029.
@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.
