Maurice 45f1ff7799 feat(planner): public transit routing via Transitous (#1065)
Each day header gets a transit button (replacing the rename pencil, which
moved next to the day name in the day detail panel). It opens a route search
backed by Transitous/MOTIS — free, open data, no paid provider: from/to stop
search with the day's own places as quick picks, depart/arrive time, mode
filters (train, subway, tram, bus, ferry, cable car) and ranking by best
route, fewer transfers or less walking. Results show local times, duration,
transfers, walking time and line badges in their official colors, with a
stop-by-stop breakdown per connection.

Adding a connection saves it as a regular transport reservation — typed by
its dominant leg, timed from the itinerary's wall-clock departure/arrival
converted to station-local time (tz-lookup), with the origin, transfer stops
and destination as endpoints and the compact legs in metadata.transit. It
slots into the day timeline by time and inherits editing, deletion and
drag-reordering from the existing transport machinery; the transport detail
view renders the full itinerary. Re-saving a transit transport through the
edit modal preserves the stored itinerary while the route is unchanged.

The server proxies the Transitous API (JWT-guarded, rate-limited, identifying
User-Agent, short response cache, strict mode whitelist); TRANSIT_API_URL
lets self-hosters use their own MOTIS instance. New i18n keys in every
locale, wiki page updated.

@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): via paths in server/tsconfig.json.
  • Client (vite): via resolve.alias in client/vite.config.ts (+ paths for 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.
