Add a Help section (profile menu, /help) that renders the GitHub wiki inside TREK. /api/help fetches the wiki markdown — the nav from _Sidebar.md, pages, and proxied images — from GitHub and caches it (1h TTL, serves stale on outage), so it auto-syncs on wiki edits with no redeploy and the client never calls GitHub directly. The page is styled to match TREK with a section sidebar, search and react-markdown; wiki [[links]] are rewritten to in-app routes and HTML-comment placeholders are stripped. Page state lives in a useHelp() hook per the page pattern. Adds nav.help and a help namespace across all 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.
