Wanjohi 51d25f3e8c fix(machine): a taken endpoint id is a conflict, not a server fault
A host reporting an endpoint id another machine already holds hit the unique
index, and the raw refusal reached the global handler as a 500 -- telling a
host its beat broke the server rather than that the id is taken. It is now the
409 every other conflict here gives, and the route documents it.

Checked-then-written would be worse rather than better: two hosts reporting the
same id in the same instant both read "nobody holds it" and both write, which
is precisely what the index is for. The read would add a query and remove
nothing.

Before:
  expect(res.status).toBe(409)
  Received: 500

apps/api

The public HTTP API for Nestri — a Hono app. One handler, run either as a Cloudflare Worker or as an ordinary HTTP server.

What it does

Exposes the JSON API consumed by frontends and other clients. Every route is a thin wrapper that validates input, delegates to a domain function in @nestri/core, and returns { data: ... }. All business logic lives in the core package.

Routes:

Prefix Purpose
/ Health check
/user Current user profile, fingerprints, linked accounts
/steam Link / sync / unlink a Steam account
/library Owned games with playtime
/games Game catalog
/pairing-code Device pairing codes
/machine Host machines
/access-token Short-lived access tokens
/doc Generated OpenAPI spec

Structure

app/
  index.ts           # The handler: middleware, routes, error handler, /doc
  server.ts          # The same handler behind a listening socket
  middleware/auth.ts # Bearer JWT + admin shared-secret auth → Actor
  routes/*.ts        # Thin route namespaces (UserApi, SteamApi, ...)
  utils/             # ErrorResponses, Result(), validator wrapping
wrangler.jsonc       # Worker configuration, one environment per stage
Dockerfile           # The container, built from the repository root
test/                # Route tests

Key details

  • Auth: Authorization: Bearer <JWT> verified against @nestri/auth; or the x-nestri-admin-token header carrying ADMIN_SHARED_SECRET, which bypasses JWT verification entirely and is required — it has no default anywhere. It is what authenticates the callers that have no user identity to present: POST /pairing-code/claim (a device being paired has no identity yet, which is the whole point), POST /games, POST /games/sync, POST /library/sync, GET /waitlist, POST /steam/link on behalf of another user, and POST /games/download-state when an operator is repairing state a box reported.
  • Errors: centralized VisibleError → typed JSON responses.
  • Settings arrive as bindings or as environment variables, and two of them have one spelling of each: Postgres is HYPERDRIVE or DATABASE_URL, and the route to the issuer is an AUTH service binding or AUTH_INTERNAL_URL. Nothing here branches on which it got.
  • AUTH_ISSUER_URL is the issuer's public URL and never the internal one, because it is compared literally against the iss claim on every token.

Running

bun run dev      # under the Workers runtime, on :3000
bun run serve    # as a plain process, on $PORT (default 3000)

Needs a Postgres database and a reachable issuer. Full list and deployment steps: docs/deploy.md.
