Setup

The project is managed and configured via mise-en-place:

• mise install will pull the correct Erlang, Elixir and Node.js versions
• mise run dev:setup will setup dependencies and database structure

Important

The project uses Fluxon UI, so it requires a valid set of credentials. See the env section in mise.toml for the required environment variables.

It's recommended to use the git hooks included in the project. Install with:

mise generate git-pre-commit --write --task=dev:precommit

Environment configuration

Required environment variables for development are listed in mise.toml.

You can create a mise.local.toml with the required variables (sample values are included at the top of mise.toml).

For production, please see compose.yaml for a list of required variables.

Running the application

Start the Phoenix endpoint with mise run console (along with an attached IEx session).

Now you can visit localhost:4000 from your browser. The default password for development is change me.

Auditing Scrobble Data Quality

The application includes a Mix task to audit scrobbled tracks and identify data quality issues such as missing MusicBrainz IDs for artists and albums.

Running the Audit

# Audit all tracks
mix scrobble.audit

# Audit with detailed output including sample tracks
mix scrobble.audit --verbose

# Audit only artist issues
mix scrobble.audit --type artist

# Audit only album issues
mix scrobble.audit --type album

# Output as JSON for processing
mix scrobble.audit --format json

Understanding the Audit Report

The audit report shows:

• Total number of scrobbled tracks
• Artists with missing MusicBrainz IDs (grouped by artist name)
• Albums with missing MusicBrainz IDs (grouped by album title and artist)
• Track counts for each issue

Fixing Data Quality Issues

After identifying issues, you can:

1. Create Scrobble Rules: Navigate to the Scrobble Rules page in the web interface and add rules to map artist or album names to their correct MusicBrainz IDs.

2. Apply Rules: Use the "Apply Rules" button in the Scrobble Rules page to update existing tracks, or run in IEx:

   MusicLibrary.ScrobbleRules.apply_all_rules()
   

3. Re-audit: Run the audit again to verify the fixes worked.

The application also provides helper functions in the MusicLibrary.ScrobbleActivity context:

• count_tracks_missing_artist_musicbrainz_id/0
• count_tracks_missing_album_musicbrainz_id/0
• get_artists_missing_musicbrainz_id/1
• get_albums_missing_musicbrainz_id/1

Deployment

The application is deployed via Coolify, using a Docker Compose strategy.

CI

See the .github folder.

Architecture

See the docs folder.
