* chore: update all dependencies
* chore: remove lint errors
* fix(client): restore typecheck after dependency bump
vitest 4 types vi.fn() as Mock<Procedure | Constructable>, which no
longer assigns to the strictly-typed onUpdate prop; type the mock
explicitly. TS6 + the new transitive @types/node 25 stopped auto-
including node builtin module types, so import('node:buffer') failed;
add @types/node as a direct client devDependency and a scoped node
type reference in the one test that needs it.
* test: fix constructor mocks for vitest 4 Reflect.construct semantics
vitest 4 resolves new-invoked mocks via Reflect.construct, which rejects
arrow-function implementations (including mockReturnValue sugar) as
non-constructable. Convert mapbox-gl and better-sqlite3 mocks that the
code instantiates with new to regular function implementations.
@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.
