# VibeSonic

VibeSonic is a lightweight, self-hosted music/media server written in Go.
It follows the same philosophy as other small `Vibe*` tools: a single Go
binary, SQLite storage, server-rendered Bootstrap 5 templates, dark mode
by default, minimal JavaScript, and no external services (no Redis, no
message broker, no microservices, nothing Kubernetes-specific).

**This is Phase 2 of 4.** Phase 1 built the foundation (config, schema,
auth, scanner, metadata, streaming, cover art, web UI shell). Phase 2
adds a **complete implementation of the original Subsonic REST API
through version 1.16.1** under `/rest/*` — every endpoint, backed by
real data, including transcoding, HLS, a real mpv-backed jukebox, and a
real podcast subsystem. See
[`docs/subsonic-compatibility.md`](docs/subsonic-compatibility.md) for
the full endpoint-by-endpoint matrix. OpenSubsonic extensions are not
yet implemented (Phase 3).

## Features

### Phase 1: foundation

- SQLite storage (WAL mode, foreign keys, versioned migrations) with a
  schema already modeling artists, albums, songs, genres, contributors,
  playlists, favorites, ratings, scrobbles, playback history, bookmarks,
  play queues, shares, podcasts, internet radio, and settings
- Native authentication: Argon2id password hashing, HTTP-only signed
  session cookies, CSRF-protected forms, session revocation
- Optional Navidrome-style external authentication via a trusted reverse
  proxy header, gated on the real TCP peer address (never on
  spoofable `X-Forwarded-For`/`X-Real-IP`/`Forwarded` headers)
- A library scanner supporting multiple music folders, incremental
  rescans, new/changed/deleted/renamed file detection, and a bounded
  worker pool — never a blind full rebuild
- Real metadata extraction via `ffprobe` (multi-artist, multi-genre,
  MusicBrainz IDs, ReplayGain, embedded artwork/lyrics, sort fields, and
  more)
- Stable, opaque, URL-safe IDs that survive restarts and rescans
- Direct media streaming with HTTP range request support, correct MIME
  types, and no full-file buffering
- Cover art discovery (embedded artwork or folder images) with a
  resized-image disk cache
- A server-rendered, dark-mode, keyboard-friendly web UI: browsing,
  search, playlists, favorites, a persistent bottom player, and an admin
  section (users, music folders, scanner status, system settings)
- `/healthz` and `/readyz`

### Phase 2: Subsonic REST API

- All 76 endpoints of the original Subsonic API through 1.16.1 —
  browsing (filesystem and ID3), search, playlists, favorites/ratings/
  scrobbling, sharing, user management with the full permission model,
  bookmarks, play queue, chat, and library scan status
- Real ffmpeg-backed transcoding (mp3/opus/aac) and HLS segmenting for
  `stream`/`hls`, bounded concurrency, killed on client disconnect
- A real podcast subsystem: RSS feed refresh, bounded background
  downloads, restart recovery, downloaded episodes stream like any other
  song
- A real jukebox backed by `mpv` over its JSON IPC socket — server-side
  playback, not a simulation; administratively unavailable (with a clear
  error) if `mpv` isn't installed
- Both original Subsonic auth modes (token/salt and password, including
  `enc:` hex), verified against an AES-256-GCM-encrypted credential kept
  separate from the Argon2id hash used for native login — see
  [`docs/subsonic-compatibility.md`](docs/subsonic-compatibility.md#authentication)
- `/rest/*` authentication is entirely independent of the browser
  session/CSRF/external-auth flow

## Quick start

```
go build -o vibesonic ./cmd/vibesonic
VIBESONIC_SESSION_SECRET=$(openssl rand -hex 32) ./vibesonic
```

Then open `http://localhost:8080` — on a fresh database you'll land on
the setup wizard, which creates the administrator account, your first
music folder, and kicks off the first scan.

`ffmpeg`/`ffprobe` should be on `PATH` (or pointed to via
`VIBESONIC_FFMPEG_PATH`/`VIBESONIC_FFPROBE_PATH`) for metadata reading,
cover art extraction, and transcoding/HLS to work. `mpv` should be on
`PATH` (or pointed to via `VIBESONIC_MPV_PATH`) for the jukebox to be
available — without it, `jukeboxControl` returns a clear "unavailable"
error rather than pretending to work.

### Docker

```
docker compose up -d
```

See [`docker-compose.yml`](docker-compose.yml) — mount your music
directory read-only at `/music` and set `VIBESONIC_SESSION_SECRET`.

### systemd

See [`systemd/vibesonic.service`](systemd/vibesonic.service).

## Configuration

VibeSonic is configured entirely through `VIBESONIC_*` environment
variables — see [`docs/configuration.md`](docs/configuration.md) for the
full list and defaults. There is no separate config file.

## Documentation

- [`docs/architecture.md`](docs/architecture.md) — how the pieces fit together
- [`docs/configuration.md`](docs/configuration.md) — every environment variable
- [`docs/external-auth.md`](docs/external-auth.md) — trusted reverse-proxy authentication
- [`docs/subsonic-compatibility.md`](docs/subsonic-compatibility.md) — protocol endpoint status

## Development

```
go fmt ./...
go vet ./...
go test ./...
```

Most tests exercise real SQLite databases and, where relevant, the real
`ffmpeg`/`ffprobe` binaries (skipped automatically if not installed).
No mocks are used for the database.
