Lets a plugin colour-code days in the Plan sidebar. trip-segments can already announce "Kanazawa begins" in the day plan, but it can't make day 12 look like it belongs to Kanazawa. dayScheduleProvider can't cover this: it renders a fixed row, and it's capped at 60 items per provider, so one item per day would tint the first 60 days of a six-month trip and silently stop. This hook is bounded by day count instead. GET /api/day-tints/:tripId returns per-day tones for three regions of a day card - the number badge (also the mobile day chip), the header row, and the expanded activity list. `tone` is a shorthand filling every region a contribution doesn't name; unnamed regions render as they do today. Tones only, never hex, so the host can pick the alpha per theme and per region. One contribution per day, resolved whole: first entry wins within a provider, first granted provider wins across plugins.
@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.
