The public share page turned every failed GET /api/shared/:token into
"Link expired or invalid". A 5xx during a restart, a proxy 502, a rate
limit, a timeout or a viewer who is briefly offline all told the viewer
the link was dead and sent them back to the owner for a new one, while
the same link loaded fine on the next try.
The endpoint answers 404 with its JSON { error } body for an unknown,
expired or revoked token, so that is now the only answer that shows the
expired screen. A 404 without that body comes from a proxy in front of
TREK (Traefik answers "404 page not found" while the container is
stopped or still starting) and counts as a failed load, as does a 200
that is not the share payload, such as an auth wall's login page, which
used to crash the page. Any failed load shows "This trip could not be
loaded" with a retry button that refetches in place and stays busy
while it runs. The load also ignores a response that lands after the
page moved on to another token.
Both screens use the theme tokens instead of hex literals. New keys are
translated in all 23 locales.
@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.
