shared's lint ran eslint --fix with prettier/prettier as an error, so in lint-prettier.yml the format:check after it only ever saw files it had just rewritten, and the server's format scripts pointed at a test/ directory that does not exist. Now lint is check-only in both (lint:fix applies fixes), the server scripts cover src/ and tests/, and a lint:format ratchet on the shared library holds every file outside scripts/format-baseline.json to Prettier in both workspaces: in the server job of test.yml and in lint-prettier.yml, which keeps providing the lint check. Formatting leaves ESLint in shared, and the unused eslint-plugin-prettier goes. Once the tree is reformatted in one commit, --update empties the baselines and the check is a full prettier --check.
@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.
