A fourth built-in channel next to email, webhook and ntfy. Browsers register per device, the server encrypts per RFC 8291 and signs per RFC 8292 with node:crypto and sends only to known push services through the SSRF guard. The event matrix decides per category what arrives by push; admins switch the channel on under Notifications. VAPID keys come from the environment or are generated once, only while neither stored row exists, and kept encrypted. A pair that does not decrypt or match is never overwritten and never swapped for another one: push stays off with an error in the log and every device stays registered until the key is fixed. The subject is VAPID_SUBJECT, then an https APP_URL, then the project URL. Only chat messages collapse into one notification per trip, and a replacement still alerts. A 403 removes a device only after three failures in a row; 404 and 410 remove it at once. Password change, reset and an admin setting a password drop the user's devices with the other credentials. The request log redacts subscriptions and endpoints, boot errors print *** for every secret variable, and logout forgets the device with a plain fetch so an expired session cannot redirect midway. Addresses discussion #894.
@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.
