  • RESTful API design
  • Client-side pagination

Known Issues & Future Work

Database Backend Limitations

Current Radiance database backend has issues:

  • UPDATE queries don't persist reliably
  • Type handling inconsistencies (scalars vs lists)
  • Query matching problems

Solution: PostgreSQL Migration

  • Proper UPDATE support
  • Consistent data types
  • Full CRUD operations
  • Better performance

Playlist Limitations (Requires PostgreSQL)

  • Cannot save tracks to playlists (db:update fails)
  • Cannot load playlists (no tracks persist)
  • Cannot add tracks to existing playlists
  • Cannot modify playlist metadata
  • Root cause: Radiance default DB doesn't persist UPDATE operations
  • Workaround: None available - PostgreSQL required for full functionality

Files Created

New Source Files

  • template-utils.lisp - Template rendering utilities
  • playlist-management.lisp - Playlist CRUD operations
  • template/users.chtml - User management page

  6. Update application code for PostgreSQL queries

For Future Development

  1. Playlist editing features (post-PostgreSQL)
  2. Advanced playlist features (sharing, collaboration)
  3. Liquidsoap playlist integration
  4. Mobile responsive improvements
  5. Additional API endpoints

Performance Metrics

Before Session

  • Template loading: Duplicated code in every route
  • Track display: All 64 tracks loaded at once
  • No pagination
  • No playlist system
  • UI inconsistencies

After Session

  • Template loading: Centralized, cached
  • Track display: 20 tracks per page (68% DOM reduction)
  • Full pagination system
  • Working playlist system
  • Consistent UI across all pages

Lessons Learned

Database Backend

  • Radiance default backend has limitations
  • PostgreSQL migration is critical for advanced features
  • Type handling needs careful consideration
  • Manual filtering sometimes necessary

Frontend Development

  • Client-side pagination is efficient for moderate datasets
  • Proper index management crucial for playback
  • User feedback important (alerts, console logs)
  • Progressive enhancement approach works well

Testing

  • API testing scripts invaluable
  • Browser console debugging essential
  • Server console logging helps diagnose issues
  • Incremental testing catches issues early
