# cdn
|
|
|
|
CDN Worker served on the `cdn` subdomain (`cdn.recflare.net`) — a Hono app that streams
|
|
the binary blobs the client downloads while playing out of the shared `recflare-cdn` R2
|
|
bucket, plus the one bundled config file the loading screen reads.
|
|
|
|
Objects are keyed by prefix — `sigs/` (anti-cheat signatures), `room/` (saved room
|
|
scenes, and room images by their bare `ImageName`), `invention/` (invention data) — and
|
|
served as `application/octet-stream`; the worker never interprets what it hands back.
|
|
Reads are unauthenticated: a caller needs the exact key, which only comes from an
|
|
authenticated call to another worker.
|
|
|
|
This worker only reads. Uploads go through `storage`, which writes the same bucket, and
|
|
images are served by `img`.
|
|
|
|
## API documentation
|
|
|
|
`GET /openapi.json` serves a spec generated from `describeRoute` blocks that sit
|
|
alongside each handler, with the schemas in `src/openapi.ts`. It's also aggregated into
|
|
the docs page www serves at `/docs`.
|
|
|
|
**The spec is descriptive, not enforced** — same rationale as the `img`/`auth` workers: a
|
|
reverse-engineered protocol, lenient handlers, no runtime validation. A test asserts
|
|
every route appears in the spec, so adding one without documenting it fails.
|
|
|
|
## Conditional and range requests
|
|
|
|
Every asset route honours `If-None-Match` (→ 304) and a single `Range` (→ 206). The range
|
|
support is not an optimization: large-file downloaders fetch in chunks, and answering 200
|
|
where a 206 is expected corrupts the reassembled file — which surfaces as an anti-cheat
|
|
"Signatures don't match" failure rather than a download error.
