File from Jammming project where we communicate with the Spotify API to get the access token to allow us to save the User's playlist to their Spotify account.

Spotify.js

//variable to hold the user's access token
let accessToken = '';

//some more variables
let clientID = '';
let redirectURI = 'http://localhost:3000/';
let url = 'https://accounts.spotify.com/authorize';


//creating the Spotify module
const Spotify = {

  getAccessToken() {
    if (accessToken !== '') {
      return accessToken;
    } else {
      fetch(`${url}?client_id=${clientID}&redirect_uri=${redirectURI}&response_type=token`).then(response => {
        if(response.ok) {
          return response.json();
        }
        throw new Error('Request failed!');
      }, networkError => console.log(networkError.message)
    ).then(jsonResponse => {
      //code to execute JSON response--is the response a URL with the token in it?
      //If so, parse the response/url and find the token and save store it into accessToken 

    });

    }//end if statement


  } //end getAccessToken method



};//end Spotify module

export default Spotify;
