- Root package.json: add workspace scripts (dev, build, test, test:cov, test:e2e) that delegate to actual scripts in shared/server/client workspaces - shared: add tsup build step (CJS + ESM dual output, .d.ts); consumers now import from the built dist instead of raw TS source via path aliases - server: replace tsc-alias with tsconfig-paths (tsc-alias mangled node_modules paths); fix MCP SDK path aliases to point to root node_modules (../node_modules) - server/scripts/dev.mjs: delay node --watch until tsc -w signals first-pass done, eliminating the spurious restart on every dev startup - client/vite.config.js + vitest.config.ts: remove @trek/shared path alias (no longer needed now that shared is a proper package) - Consolidate package-lock.json at the workspace root; drop per-workspace lock files
@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.
