An iPhone or iPad running TREK from the Home Screen ignores print(), in the page and in an iframe alike, so "Save as PDF" in the preview did nothing there. Mobile Safari prints the same preview fine. In the installed iOS app the preview now shows "Open in Safari" in place of the dead button, with a line saying why. The link opens the trip with ?export=pdf, and both shells open their export dialog or sheet for it, so the PDF is one tap away once Safari is up. The parameter is dropped once read and survives the login redirect. Everywhere else the preview prints as before. The preview overlay moves out of TripPDF.tsx into pdfPreview.ts, which TripPDF had no room left for under lint:size, and its backdrop and stacking now use the --overlay and --z-modal tokens.
@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.
