- ShareCollectionModal: the owner manages a list's members and invites users (available-users picker → invite, cancel pending); a member can leave a shared list. The incoming accept/decline surface stays in the lists rail. A Share button is added to the collections header for owners (and members, to reach Leave). - CollectionsWidget: a dashboard glass card after the currency widget showing the saved count and the most recent saved places, double-gated by the admin addon and a new per-user appearance flag. - Appearance: a 'collections' dashboard-widget flag (desktop + mobile defaults) wired into the appearance settings, surviving normalize. - Sharing + settings strings across all 22 locales (parity strict passes).
@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.
