The PBF reader streams the extract and refuses a varint longer than ten bytes; the block offsets are read as the plain int64 the format defines. Region reads queue without loose promises: a region queued while another is read is still picked up, removing a region calls its read off, a shutdown stops the read under way and the next boot queues it again and clears the download folder. The admin list shows how far a read has come. Geofabrik is asked only on its own servers, redirects included, and an outage of its list answers 502 instead of an unknown region. Nested ids such as us/texas are accepted. A region being read again or after a failed read still counts with the data it holds, a region without a boundary spans its objects, and an object two overlapping regions hold is answered once. Stored geometry, tags and boundaries go through the JSON column declarations. An obstacle is related to the route both ways, so a long weir passed in its middle and a route inside an area count. Tests cover the reader with extracts written in the test, the tag rules, the extraction and lock grouping, the geo helpers, the Geofabrik client, the region queue, the read side, both controllers, the job, the repositories and the HTTP routes; the domain gets its coverage entry.
@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.
