A road trip tab on the mobile trip screen: the stage as a chain, the same map underneath it, the sheets a passenger needs, and a search along the route. The addon was desktop only because road trip MODE is a data switch rather than a view switch. It rewrites `assignments` and `places` for the whole planner hook, and every mobile sheet is permanently mounted and reads those same two lists, so turning it on there brought back documented regressions. The mode flag is therefore untouched. A second flag, `roadtripFeedActive`, feeds only the routing round and does it off the STORED assignments, so the phone gets the drive without what the mode drags along with it. The map is one instance shared by the plan tab and the road trip tab, hoisted into a single JSX expression so React keeps it in the same position and the WebGL context is never torn down on a tab switch. The corridor search is scoped to what a phone can afford: a window of the day rather than all of it, a smaller tile ceiling, a capped retry pass and a deadline. The standard search is three requests where the desk makes fifteen. The categories are deliberately not narrowed, because they all ride one query per box, so a second one costs nothing. Two gaps found while wiring it up are closed here as well. The fuel search drew its offers nowhere on the phone, so the button did nothing visible; they are in the dry band now, with the detour, the spare range and an accept button. And the map credit opened as a two line ribbon across a screen the map fills: both GL engines now start it collapsed, and Leaflet, which has no collapsed mode of its own, is given one.
@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.
