Small requests from the discussions, each built end to end: planner and map (cycling mode, date first headings, clear a day, stay times per day, off-route stops, map lock, compact unplanned markers, pending stays, cable car, transit quick picks), places (location filter, category from OSM, open in maps, geo: link, image from an attachment, enrichment on file import, places near a pin, place name language, Amap first in China), lists and costs (packed counter, inherited sharing, Markdown to-dos, payment notes, bookings CSV, my plan PDF), sharing (unplanned places, travel only, without photos), journey (photo zoom, drafts, photo order, trip suggestion, day jump), atlas (region counter, region bucket list, places per country), vacay half company holidays, studio copy and paste plus the book's own layouts, and RESTORE_FROM_BACKUP for a first start restore.
@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.
