This is a minimal example to try out the Spotify Authorization flow with PKCE.
I highly recommend to read the offical Spotify guide about authorization: https://developer.spotify.com/documentation/general/guides/authorization-guide/#authorization-code-flow-with-proof-key-for-code-exchange-pkce
In order to test this project you need to create an app in your Spotify Dashboard: https://developer.spotify.com/dashboard/applications
Here you will find the CLIENT_ID that you need to copy inside the main.js on line 233.
Don't forget to also add the redirect URI to your application.
To locally host this example http-server is used.
First install the dependecies by running npm install.
Then serve the files in the public folder via npm start
