Specifies POST /api/events with start+end semantics, session service (30-min rolling), play/skip classification (spec §6 boundaries), sendBeacon + auto-close-on-next-start for abandoned plays, and Subsonic /rest/scrobble integration that writes synthetic completed plays so third-party clients feed the recommendation pipeline. Schema migration ships the full M2 set (play_events, skip_events, sessions) including M3-only nullable columns so M3 doesn't need a follow-up migration. General likes deferred to a separate M2 sub-plan; this slice covers spec §13 step 5 only.
Minstrel
Self-hosted music server with OpenSubsonic compatibility plus an extended API for server-side smart shuffle, a dual-like model (general + contextual), session-aware radio, ListenBrainz scrobble/similarity, and Lidarr integration. Go + Postgres, packaged as a Docker container.
State and intelligence belong on the server, not the client.
Specs
Authoritative v1 scope lives under docs/:
- Server spec — current implementation focus.
- Client spec — Flutter companion app; work starts once the server reaches its Subsonic-compatible baseline.
Development workflow
- Day-to-day work happens on the
devbranch (or feature branches merged intodev). mainis protected — changes land only via pull request fromdev.- Production builds are cut by tagging a release (
v*) offmain.
CI / container image
Forgejo Actions handles:
- Tests on push to
devand on PRs intomain. - Container image build + push to the Forgejo registry on merge to
main(:main) and onv*tags (:<version>).
Task and milestone tracking: Fable (Minstrel project, id 12).
Development
Minstrel has two concurrent dev processes:
- Backend:
docker compose up— starts Postgres and Minstrel on:4533. - Frontend:
cd web && npm install && npm run dev— Vite dev server on:5173with HMR.
The Vite dev server proxies /api/* and /rest/* to the backend on :4533,
so session cookies work correctly when the SPA is loaded from the Vite origin.
Production build
docker build -t minstrel . runs the SvelteKit build inside a node stage,
copies the output into the golang stage, and //go:embeds it into the
final binary. The resulting container serves the SPA from / alongside the
API surfaces. No separate static-file server is required.
