New tripInviteLinkCreateRequestSchema in @trek/shared (single source of truth), a createZodDto wrapper on the controller's raw @Body(), and the TripInviteLinkController.create entry dropped from the body-contract allow-list (the boot ratchet enforces it). expires_in_days accepts number | digits-only string | null | absent — the string branch is digits-only so garbage like "7abc" is a 400 instead of silently parseInt-ing to 7; the empty string (blank form input, meaning no expiry) stays accepted. The e2e registers ZodValidationPipe and pins both the bounded-expiry and 400 paths.
@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.
