JuhoKon/tubemusic
Dec 2019 - May 2021
Independent hobby project using a React frontend and Node backend (MERN-stack). Application made for listening music from YouTube and making playlists & adding songs to queue. I listen to a lot of music and wanted to make it easier to use YouTube for music. I am developing the app on my free time. The system uses the Spotify API for importing songs from spotify to the application.
