The apps ship only an address screen now. Once a server is picked, the native side points the WebView at it: TrekBridgeViewController on iOS and a config copy with server.url on Android. The UI then comes from that server, in the version it runs and on its own origin, so the session cookie, uploads, /ws and plugins work exactly as in a browser and no app release has to keep pace with the servers out there. The address screen (native-shell/, built into native-dist/) probes /api/health/features through native HTTP, tries https before http when no scheme was typed, and refuses servers without the nativeApp flag. It also serves as the error page when the remembered server does not load: retry, change server, or on iOS the stored copy of the server's start page. TrekShell is the app's own plugin for all of that: remember, change and reload the server, sign in through ASWebAuthenticationSession or a Custom Tab, and on iOS keep and open the offline copy of the start page, because WKWebView runs no service worker for a domain the app does not list. Plugins the frame does not use are gone (push, camera, geolocation, calendar, file transfer, in-app browser and more): the WebView covers the camera and location itself, and push needs a relay before it is worth shipping. With them go the push entitlement, the calendar usage strings and the Firebase bits. The iOS scheme falls back to capacitor://, since Capacitor drops an iosScheme of https, and the arm64 capability replaces armv7.
@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.
