- RTL: the measured pills and centred controls use logical forms or a marked line - i18n: the two native widget numbers are positions, not counts (NOT_PLURAL) - Types: styleOverride on the lazy GL map, the location and shared-file payloads, the capabilities fallback, the transport sheet's stay metadata - ESLint: latest-value refs move to layout effects, usePresence keeps the last open state in state, the booking import opens clean with a shared document kept in the list (the reset effect used to clear it again) - Layers: the phone import sheet lives under mobile/ and reads through tripRepo; the offline host check moves to utils/tileUrl - Sizes: plugin layer geometry, hardNavigate and the exit animations get modules of their own - Tests follow the status radios, the stay chip overview, the dock + button for the first list and the field token; store registry lists the new stores
@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.
