So I'm Working on a NodeJs project and am wondering if there is a way to get audio from Spotify Like you Input a song URL and It plays the track, I've looked all around and can only find stuff for the web browser, I don't know if they even have a way. If there is any info about this please let me know.
You'd have to make calls through the Spotify API.
You can read more about the API here: Spotify API Documentation
This is a node.js specific library that you may also want to check out: thelinmichael's node.js Spotify API Library
