BODY_CONTRACT_ALLOW_LIST is empty. The last seventeen handlers type their
body with a createZodDto class, so the fail-closed boot gate has nothing left
to forgive; it still refuses a boot for a new handler that reads @Body()
without one.
Several of those contracts describe rather than constrain, and that is the
whole care in this change. The pipe runs before the handler, so a schema
stricter than the handler moves a user-visible answer:
- TagsController.create answers { error: 'Tag name is required' }, pinned
byte-for-byte in two tests, and the pipe formats as `field: message`. The
DTO leaves name optional and the handler keeps the check that owns the
message. Same shape for the booking-import confirm body, which additionally
gains per-item validation the handler never did.
- PluginsController.activate and install answer 503 when plugins are disabled,
and check that BEFORE looking at the body. A schema that rejected first
would turn that into a 400 for an operator whose server has plugins off.
- setEgressHosts reads a non-array `hosts` as "clear the list", which is the
documented reset. Typing it as string[] would have removed a working admin
action rather than tightened anything.
- PluginRoutesController.route answers { route: null } at 200 for everything
it dislikes, so the client falls back to straight lines. A 400 there would
turn a graceful degradation into a visible error.
files.bridge is gone. The multer options are built by
MulterModule.registerAsync from an AllowedFileTypesService leaf, so the
fileFilter reads the operator's extension list from the container instead of
from a second FilesService built outside it. Nest injects
MULTER_MODULE_OPTIONS with @Optional(), so a token that fails to resolve is
not a boot error: it silently falls back to defaults, with no filter and no
size cap. FILE-020 already proved that for trip files by uploading an .svg
over HTTP and expecting 400; journey uploads had no such case, and now do.
VIDEO_UPLOAD is untouched, including the filename callback that forces .jpg
regardless of what the client sends, which guards the public share proxy.
PluginFrame gets an onError. A frame whose document fails to load left a
blank element at full height, which reads as a hung app rather than as a
plugin that is gone.
typecheck:tests runs in CI now, with the test tree at zero errors. tz-lookup
is left as it is: the build puts it in a lazy helpers chunk, not the entry
chunk, and the remaining split would trade a synchronous render for an async
one to move 172 kB that is already off the critical path.
@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.
