A Node.js wrapper for Spotify's Web API
This is a Node.js wrapper/client for the Spotify Web API. If you want to make requests directly from the browser, please check out spotify-web-api-js. 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:
Some methods require authentication, which can be done using these flows:
Even though authentication isn't always necessary, it always gives benefits such as an increased rate limit.
$ npm install spotify-web-api-node --save
First, instantiate the wrapper.
var SpotifyWebApi = require'spotify-web-api-node';// 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' albumsspotifyApigetArtistAlbums'43ZHCT0cAZBISjO8DG9PnE'thenconsole.log'Artist albums' databody;console.errorerr;;
If you dont wan't to use promises, you can provide a callback method instead.
// Get Elvis' albumsspotifyApigetArtistAlbums'43ZHCT0cAZBISjO8DG9PnE' limit: 10 offset: 20if errconsole.error'Something went wrong!';elseconsole.logdatabody;;
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]spotifyApigetArtistAlbums'43ZHCT0cAZBISjO8DG9PnE' limit: 10 offset: 20thenconsole.log'Album information' databody;console.errorerr;;
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 in a request is not always required by the API (see the Endpoint reference for details), but it will give your application benefits such as a higher rate limit. 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.
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 = spotifyApicreateAuthorizeURLscopes state;//console.logauthorizeURL;
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 tokenspotifyApiauthorizationCodeGrantcodethenconsole.log'The token expires in ' + databody'expires_in';console.log'The access token is ' + databody'access_token';console.log'The refresh token is ' + databody'refresh_token';// Set the access token on the API object to use it in later callsspotifyApisetAccessTokendatabody'access_token';spotifyApisetRefreshTokendatabody'refresh_token';console.log'Something went wrong!' err;;
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.spotifyApirefreshAccessTokenthenconsole.log'The access token has been refreshed!';console.log'Could not refresh access token' err;;
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.spotifyApiclientCredentialsGrantthenconsole.log'The access token expires in ' + databody'expires_in';console.log'The access token is ' + databody'access_token';// Save the access token so that it's used in future callsspotifyApisetAccessTokendatabody'access_token';console.log'Something went wrong when retrieving an access token' err;;
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 = ;spotifyApisetAccessToken'myAccessToken';spotifyApisetRefreshToken'myRefreshToken';spotifyApisetRedirectURI'';spotifyApisetClientId'myOwnClientId';spotifyApisetClientSecret'someSuperSecretString';// Set all credentials at the same timespotifyApisetCredentials'accessToken' : 'myAccessToken''refreshToken' : 'myRefreshToken''redirectUri' : '''clientId ' : 'myClientId''clientSecret' : 'myClientSecret';// Get the credentials one by oneconsole.log'The access token is ' + spotifyApigetAccessToken;console.log'The refresh token is ' + spotifyApigetRefreshToken;console.log'The redirectURI is ' + spotifyApigetRedirectURI;console.log'The client ID is ' + spotifyApigetClientId;console.log'The client secret is ' + spotifyApigetClientSecret;// Get all credentialsconsole.log'The credentials are ' + spotifyApigetCredentials;// Reset the credentialsspotifyApiresetAccessToken;spotifyApiresetRefreshToken;spotifyApiresetRedirectURI;spotifyApiresetClientId;spotifyApiresetClientSecret;spotifyApiresetCode;// Reset all credentials at the same timespotifyApiresetCredentials;
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 setterspotifyApiclientCredentialsGrantthenconsole.log'The access token is ' + databody'access_token';spotifyApisetAccessTokendatabody'access_token';console.log'Something went wrong!' err;;
