This is a universal wrapper/client for the Spotify Web API that runs on Node.JS and the browser, using browserify/webpack/rollup. A list of selected wrappers for different languages and environments is available at the Developer site's Libraries page.
It includes helper functions to do the following:
All methods require authentication, which can be done using these flows:
$ npm install spotify-web-api-node --save
First, instantiate the wrapper.
var SpotifyWebApi = ;// credentials are optionalvar spotifyApi =clientId : 'fcecfc72172e4cd267473117a17cbd4d'clientSecret : 'a6338157c9bb5ac9c71924cb2940e1a7'redirectUri : '';
If you've got an access token and want to use it for all calls, simply use the api object's set method. Handling credentials is described in detail in the Authorization section.
Lastly, use the wrapper's helper methods to make the request to Spotify's Web API. The wrapper uses promises, so you need to provide a success callback as well as an error callback.
// Get Elvis' albumsspotifyApi;
If you dont wan't to use promises, you can provide a callback method instead.
// Get Elvis' albumsspotifyApi;
The functions that fetch data from the API also accept a JSON object with a set of options. For example, limit and offset can be used in functions that returns paginated results, such as search and retrieving an artist's albums.
Note that the options parameter is currently required if you're using callback methods.
// Passing a callback - get Elvis' albums in range [20...29]spotifyApi;
To enable caching, this wrapper now exposes the response headers and not just the response body. Since version 2.0.0, the response object has the format
In previous versions, the response object was the same as the response body.
Retrieving a track's metadata in
spotify-web-api-node version 1.4.0 and later
The response object for the same request in earlier versions than to 2.0.0.
Below are examples for all helper functions. Longer examples of some requests can be found in the examples folder.
Please note that since version 1.3.2 all methods accept an optional callback method as their last parameter. These examples however only use promises.

Supplying an access token is required for all requests to the Spotify API. This wrapper supports two authorization flows - The Authorization Code flow (signed by a user), and the Client Credentials flow (application authentication - the user isn't involved). See Spotify's Authorization guide for detailed information on these flows.
Important: If you are writing a universal/isomorphic web app using this library, you will not be able to use those methods that send a client secret to the Spotify authorization service. Client secrets should be kept server-side and not exposed. Never include your client secret in the public JS served to the browser.
With the application created and its redirect URI set, the only thing necessary for the application to retrieve an authorization code is the user's permission. Which permissions you're able to ask for is documented in Spotify's Using Scopes section.
In order to get permissions, you need to direct the user to our Accounts service. Generate the URL by using the wrapper's authorization URL method.
var scopes = 'user-read-private' 'user-read-email'redirectUri = ''clientId = '5fe01282e44241328a84e7c5cc169165'state = 'some-state-of-my-choice';// Setting credentials can be done in the wrapper's constructor, or using the API object's setters.var spotifyApi =redirectUri : redirectUriclientId : clientId;// Create the authorization URLvar authorizeURL = spotifyApi;//console;
The example below uses a hardcoded authorization code, retrieved from the Accounts service as described above.
var credentials =clientId : 'someClientId'clientSecret : 'someClientSecret'redirectUri : '';var spotifyApi = credentials;// The code that's returned as a query parameter to the redirect URIvar code = 'MQCbtKe23z7YzzS44KzZzZgjQa621hgSzHN';// Retrieve an access token and a refresh tokenspotifyApi;
Since the access token was set on the api object in the previous success callback, it's going to be used in future calls. As it was retrieved using the Authorization Code flow, it can also be refreshed unless it has expired.
// clientId, clientSecret and refreshToken has been set on the api object previous to this call.spotifyApi;
The Client Credential flow doesn't require the user to give permissions, so it's suitable for requests where the application just needs to authenticate itself. This is the case with for example retrieving a playlist. However, note that the access token cannot be refreshed, and that it isn't connected to a specific user.
var clientId = 'someClientId'clientSecret = 'someClientSecret';// Create the api object with the credentialsvar spotifyApi =clientId : clientIdclientSecret : clientSecret;// Retrieve an access token.spotifyApi;
Credentials are either set when constructing the API object or set after the object has been created using setters. They can be set all at once or one at a time.
Using setters, getters and resetters.
// Use setters to set all credentials one by onevar spotifyApi = ;spotifyApi;spotifyApi;spotifyApi;spotifyApi;spotifyApi;// Set all credentials at the same timespotifyApi;// Get the credentials one by oneconsole;console;console;console;console;// Get all credentialsconsole;// Reset the credentialsspotifyApi;spotifyApi;spotifyApi;spotifyApi;spotifyApi;spotifyApi;// Reset all credentials at the same timespotifyApi;
Using the constructor.
// Set necessary parts of the credentials on the constructorvar spotifyApi =clientId : 'myClientId'clientSecret : 'myClientSecret';// Get an access token and 'save' it using a setterspotifyApi;
// Set the credentials when making the requestvar spotifyApi =accessToken : 'njd9wng4d0ycwnn3g4d1jm30yig4d27iom5lg4d3';// Do search using the access tokenspotifyApi;
// Set the credentials when making the requestvar spotifyApi =accessToken : 'njd9wng4d0ycwnn3g4d1jm30yig4d27iom5lg4d3';// Get tracks in a playlistapi;
