- Packing: a ring of what is in the bags, each bag against its weight limit, the items still missing in their bag's colour, a nudge when departure is two days or less away - World map: the world as dots from the Atlas country shapes (WorldGrid.swift, generated by WidgetPreviews/make-world-grid.py), the visited countries glowing, the latest one ringed, continents as bars and the latest countries with their flags; it needs no trip - Travel group: who comes along as avatars, the latest chat messages as bubbles and the open poll with its votes as bars - The to-dos widget is about to-dos only; the packing ring moved out The app sends the bags, the Atlas countries (an hour's cache) and the chat and poll with the snapshot; all optional, as before.
@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.
