Hi everyone,
I am finally getting to the end of the jamming project, with the help of the forum I was able to correct some of the issues I had with my code but cannot figure out what this one means.
Any pointers would be greatly appreciated. I have checked the forum and the project walkthrough but at this point, I am completely stuck.
const clientId = '';
const redirectUri = 'http://localhost:3000/';
let accessToken;
const Spotify = {
getAccessToken(){
if(accessToken){
return accessToken;
}
// check for access token match
const accessTokenMatch = window.location.href.match(/access_token=([^&]*)/);
const expiresInMatch = window.location.href.match(/expires_in=([^&]*)/);
if (accessTokenMatch && expiresInMatch){
accessToken = accessTokenMatch[1];
const expiresIn = Number(expiresInMatch[1]);
window.setTimeout(() => accessToken = '', expiresIn * 1000);
window.history.pushState('Access Token', null, '/');
return accessToken;
} else {
const accessUrl = `https://accounts.spotify.com/authorize?client_id=${clientId}&response_type=token&scope=playlist-modify-public&redirect_uri=${redirectUri}`;
window.location = accessUrl;
}
},
search(term){
const accessToken = Spotify.getAccessToken();
return fetch(`https://api.spotify.com/v1/search?type=track&q=${term}`, { headers: {
Authorization: `Bearer ${accessToken}`
}
}).then(response => {
return response.json();
}).then(jsonResponse => {
if (!jsonResponse.tracks) {
return [];
}
return jsonResponse.tracks.items.map(track => ({
id: track.id,
name: track.name,
artist: track.artists[0].name,
album: track.album.name,
uri: track.uri
}));
});
},
savePlaylist(name, trackUris){
if(!name || !trackUris.length){
return;
}
const accessToken = Spotify.getAccessToken();
const headers = { Authorization: `Bearer ${accessToken}`};
let userId;
return fetch('https://api.spotify.com/v1/me', {
headers: headers }
).then(response => response.json()
).then(jsonResponse => {
userId = jsonResponse.id;
return fetch(`https://api.spotify.com/v1/users/${userId}/ playlists`,
{
hearders: headers,

const playlistId = jsonResponse.id;
return fetch(`https://api.spotify.com//v1/users/${userId}/playlists/${playlistId}/tracks`, {

Doing the Ravenous part 4 project but it’s probably the same thing for me
