Attempt V2, and still a work in progress.
A React, P5.js and Express.js project that creates a music visualizer as a Spotify Connect device, enabling you to authenticate with a Spotify Premium account and get real-time audio visualizations to your music playback.
Huge huge thanks to Zach Winter for his help on this, there is no way I would have been able to get going without his amazingly generous help. A large proportion of the code used to get me going on this is by his fingers. I will comment this accordingly once the project becomes more complete. ๐
