The question before a day goes now also says which day without a date takes over the last date, which stay running across the day loses a night and when it checks out, and what the cancelled booking costs, or that it has no expense at all; further bookings on the same stay are counted. Road trip boundaries follow their own days when the numbering still has a hole from the old delete, and ones left on no day are dropped. A long list scrolls inside the confirm card on both shells with the buttons always in reach, Escape closes only the sheet on top and takes the trip dialog back from its review step to the form, and the panel of a deleted day closes, also when a fellow traveller deletes it. Undo steps on a deleted day are dropped, a restored place skips days that are gone, and an undo that fails says so. The day cache is written without holding up the answer once the server has it, the tip under a new start date points at the dated add button, and two Collab tests find the confirm button by its role instead of an old colour class.
@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.
