Provides data and makes Spotify API calls for React front end (repo)
~~View live site here (please be patient while Heroku wakes up)~~ down temporarily - please see demo below instead

Features

Authorizes users through Spotify's Authorization Code Flow, in tandem with front end
Requires authorization for all API requests
Utilizes Ruby's Thread class to avoid IO blocking when persisting a user's saved library data (which may take anywhere from a few seconds to a couple of minutes depending on its size)

See app for application code
Utilizes the Spotify Web API to authorize users and access private data
- In order to use this repo, you must register your app with Spotify and store the client id, secret key, redirect uri, etc. as environment variables (I recommend the Figaro gem)
PostreSQL database stores basic user info and library data
