I would recommend setting up a GET route and then when you receive a GET request,
printing something to the console so you know it worked.

Express does this automagically for you

I would recommend setting up a route:
localhost:8000/spotify-related?id=12345
Then on the server, try to get the 12345 part and print it out to the console to make sure it worked.

Some quick dotenv stuff. Make sure the .env file is in your repo (I sent it on slack, it contains our Spotify API key and other sensitive info)

Once you have the route working properly and returning some JSON data to the client, you should have the GET request trigger a request to Spotify from Node. You'll need to use request or axios library for this.

Postman App - You can use this to create any type of request to test your server.
Once you follow the Node / Express tutorial, you should have an app running at
localhost:8000
You can then send requests to
localhost:8000/some-route-you-just-created
using Postman.
