Foobar2000 Web UI application consists of two parts:

• A Node.js server that controls foobar2000 music player using native CLI commands and foo_controlserver component (a tcp/ip server for foobar2000).
• A web application that allows the user to send basic foobar2000 playback commands and adjust application volume level. Information about the track that is currently playing is also displayed and automatically updated when the track or playback status changes.
