Wanjohi ac713e62ae feat(billing): sizes move up one; 1080p is the reference and the default
xs is a box with no stream, sm 720p, md 1080p, lg 1440p and xl 4K. Each
resolution keeps its price, so md is now 1x. New boxes default to md, and
existing boxes move up one size so none of them drops a resolution.

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, access token or host credentials → 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 …, carrying either a session token verified against @nestri/auth or a personal access token resolved from the database; or a registered host's own x-nestri-machine-id and x-nestri-machine-secret. There is no shared secret and no credential that stands for more than one caller, so every route resolves to a specific user or a specific host — which is what lets a route say "the caller's own library" and mean it.
  • 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.
