The app

Musa is a user interface for musa-electron and musa-server made with React. It is an exploration into how to create a cross-platform music player utilising Electron and React. It supports mp3, flac and ogg files and jpeg, png and webp images. It works on Linux, MacOS and Windows.

Development

1. npm install
2. npm run start:e
3. Start musa-electron

Known issues

• On (Debian) Linux it is possible for bluetooth to stop working in the Electron version. I suspect this might be because the AudioContext gets directed to another output like speakers and for whatever reason does not get directed back to the bluetooth headphones. Closing the bluetooth headphones and reconnecting them should fix the problem, at least after reopening the app.

Stuff to know

Musa expects this folder structure

|_Library folder
  |_Artist folder
    |_Artist album folder
      |_Artist album files OR
      |_Album may be split into multiple folders
        |_Artist album multiple folder files
        |_...
    | Artist miscellaneous files
      |_...
  |_...

because reading metadata is an expensive operation, while reading the folder structure is very fast, so changes to the library folder files are faster to determine based on the structure and file stats than by updating metadata.

All the other APIs and stuffs do use the metadata however and as a fallback what's on the filesystem, like filename.
