Spotify Web API Node

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.

Project owners are thelinmichael and JMPerez, with help from a lot of awesome contributors.

Version 5

:warning: Since the last release (4.0.0, released over year ago) a lot of new functionality has been added by a lot of different contributors. Thank you. In order to implement some of the feature requests, some breaking changes had to be made. A list of them, along with a list of the new functionality, can be found in the CHANGELOG.

• Authorization code grant (Signed by user)
• Implicit Grant Flow (Client-side Authentication)

Dependencies

This project depends on superagent to make HTTP requests.

Installation

$ npm install spotify-web-api-node --save

Usage

First, instantiate the wrapper.

var SpotifyWebApi = require('spotify-web-api-node');

// credentials are optional
var spotifyApi = new SpotifyWebApi({
  clientId: 'fcecfc72172e4cd267473117a17cbd4d',
  clientSecret: 'a6338157c9bb5ac9c71924cb2940e1a7',
  redirectUri: 'http://www.example.com/callback'
});

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.

spotifyApi.setAccessToken('<your_access_token>');

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' albums
spotifyApi.getArtistAlbums('43ZHCT0cAZBISjO8DG9PnE').then(
  function(data) {
    console.log('Artist albums', data.body);
  },
  function(err) {
    console.error(err);
  }
);

If you dont wan't to use promises, you can provide a callback method instead.

// Get Elvis' albums
spotifyApi.getArtistAlbums(
  '43ZHCT0cAZBISjO8DG9PnE',
  { limit: 10, offset: 20 },
  function(err, data) {
    if (err) {
      console.error('Something went wrong!');
    } else {
      console.log(data.body);
    }
  }
);

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 required if you're using a callback method., even if it's empty.

// Passing a callback - get Elvis' albums in range [20...29]
spotifyApi
  .getArtistAlbums('43ZHCT0cAZBISjO8DG9PnE', { limit: 10, offset: 20 })
  .then(
    function(data) {
      console.log('Album information', data.body);
    },
    function(err) {
      console.error(err);
    }
  );

Responses and errors

This exposes the response headers, status code and body.

{
  "body" : {

  },
  "headers" : {

  },
  "statusCode" :
}

Errors have same fields, as well as a human readable message. This is especially useful since Spotify's Web API returns different types of error objects depending on the endpoint being called.

Example of a response

Retrieving a track's metadata in spotify-web-api-node version 1.4.0 and later:

{
  "body": {
    "name": "Golpe Maestro",
    "popularity": 42,
    "preview_url":
      "https://p.scdn.co/mp3-preview/4ac44a56e3a4b7b354c1273d7550bbad38c51f5d",
    "track_number": 1,
    "type": "track",
    "uri": "spotify:track:3Qm86XLflmIXVm1wcwkgDK"
  },
  "headers": {
    "date": "Fri, 27 Feb 2015 09:25:48 GMT",
    "content-type": "application/json; charset=utf-8",
    "cache-control": "public, max-age=7200"
  },
  "statusCode": 200
}

Authorization

Supplying an access token is required for all requests to the Spotify API. This wrapper supports three authorization flows - The Authorization Code flow (signed by a user), the Client Credentials flow (application authentication - the user isn't involved), and the Implicit Grant Flow (For completely clientside applications). 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 methods that send a client secret to the Spotify authorization service. Client secrets should be kept server-side and not exposed to client browsers. Never include your client secret in the public JS served to the browser.

The first thing you need to do is to create an application. A step-by-step tutorial is offered by Spotify in this tutorial.

Authorization code flow

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 Spotify's Accounts service. Generate the URL by using the wrapper's authorization URL method.

var scopes = ['user-read-private', 'user-read-email'],
  redirectUri = 'https://example.com/callback',
  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 = new SpotifyWebApi({
  redirectUri: redirectUri,
  clientId: clientId
});

// Create the authorization URL
var authorizeURL = spotifyApi.createAuthorizeURL(scopes, state);

// https://accounts.spotify.com:443/authorize?client_id=5fe01282e44241328a84e7c5cc169165&response_type=code&redirect_uri=https://example.com/callback&scope=user-read-private%20user-read-email&state=some-state-of-my-choice
console.log(authorizeURL);

The example below uses a hardcoded authorization code, retrieved from the Accounts service as described above.

var credentials = {
  clientId: 'someClientId',
  clientSecret: 'someClientSecret',
  redirectUri: 'http://www.michaelthelin.se/test-callback'
};

var spotifyApi = new SpotifyWebApi(credentials);

// The code that's returned as a query parameter to the redirect URI
var code = 'MQCbtKe23z7YzzS44KzZzZgjQa621hgSzHN';

// Retrieve an access token and a refresh token
spotifyApi.authorizationCodeGrant(code).then(
  function(data) {
    console.log('The token expires in ' + data.body['expires_in']);
    console.log('The access token is ' + data.body['access_token']);
    console.log('The refresh token is ' + data.body['refresh_token']);

    // Set the access token on the API object to use it in later calls
    spotifyApi.setAccessToken(data.body['access_token']);
    spotifyApi.setRefreshToken(data.body['refresh_token']);
  },
  function(err) {
    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.

// clientId, clientSecret and refreshToken has been set on the api object previous to this call.
spotifyApi.refreshAccessToken().then(
  function(data) {
    console.log('The access token has been refreshed!');

    // Save the access token so that it's used in future calls
    spotifyApi.setAccessToken(data.body['access_token']);
  },
  function(err) {
    console.log('Could not refresh access token', err);
  }
);

Client Credential flow

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 credentials
var spotifyApi = new SpotifyWebApi({
  clientId: clientId,
  clientSecret: clientSecret
});

// Retrieve an access token.
spotifyApi.clientCredentialsGrant().then(
  function(data) {
    console.log('The access token expires in ' + data.body['expires_in']);
    console.log('The access token is ' + data.body['access_token']);

    // Save the access token so that it's used in future calls
    spotifyApi.setAccessToken(data.body['access_token']);
  },
  function(err) {
    console.log('Something went wrong when retrieving an access token', err);
  }
);

Implicit Grant flow

The Implicit Grant can be used to allow users to login to your completely client-side application. This method still requires a registered application, but won't expose your client secret. This method of authentication won't return any refresh tokens, so you will need to fully reauthenticate the user everytime a token expires.

var scopes = ['user-read-private', 'user-read-email'],
  redirectUri = 'https://example.com/callback',
  clientId = '5fe01282e44241328a84e7c5cc169165',
  state = 'some-state-of-my-choice',
  showDialog = true,
  responseType = 'token';

// Setting credentials can be done in the wrapper's constructor, or using the API object's setters.
var spotifyApi = new SpotifyWebApi({
  redirectUri: redirectUri,
  clientId: clientId
});

// Create the authorization URL
var authorizeURL = spotifyApi.createAuthorizeURL(
  scopes,
  state,
  showDialog,
  responseType
);

// https://accounts.spotify.com/authorize?client_id=5fe01282e44241328a84e7c5cc169165&response_type=token&redirect_uri=https://example.com/callback&scope=user-read-private%20user-read-email&state=some-state-of-my-choice&show_dialog=true
console.log(authorizeURL);

When the client returns, it will have a token we can directly pass to the library:

// The code that's returned as a hash fragment query string parameter to the redirect URI
var code = 'MQCbtKe23z7YzzS44KzZzZgjQa621hgSzHN';
var credentials = {
  clientId: 'someClientId',
  clientSecret: 'someClientSecret',
  //Either here
  accessToken: code
};

var spotifyApi = new SpotifyWebApi(credentials);

//Or with a method
spotifyApi.setAccessToken(code);

Setting credentials

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 one
var spotifyApi = new SpotifyWebApi();
spotifyApi.setAccessToken('myAccessToken');
spotifyApi.setRefreshToken('myRefreshToken');
spotifyApi.setRedirectURI('http://www.example.com/test-callback');
spotifyApi.setClientId('myOwnClientId');
spotifyApi.setClientSecret('someSuperSecretString');

// Set all credentials at the same time
spotifyApi.setCredentials({
  accessToken: 'myAccessToken',
  refreshToken: 'myRefreshToken',
  redirectUri: 'http://www.example.com/test-callback',
  'clientId ': 'myClientId',
  clientSecret: 'myClientSecret'
});

// Get the credentials one by one
console.log('The access token is ' + spotifyApi.getAccessToken());
console.log('The refresh token is ' + spotifyApi.getRefreshToken());
console.log('The redirectURI is ' + spotifyApi.getRedirectURI());
console.log('The client ID is ' + spotifyApi.getClientId());
console.log('The client secret is ' + spotifyApi.getClientSecret());

// Get all credentials
console.log('The credentials are ' + spotifyApi.getCredentials());

// Reset the credentials
spotifyApi.resetAccessToken();
spotifyApi.resetRefreshToken();
spotifyApi.resetRedirectURI();
spotifyApi.resetClientId();
spotifyApi.resetClientSecret();
spotifyApi.resetCode();

// Reset all credentials at the same time
spotifyApi.resetCredentials();

Using the constructor.

// Set necessary parts of the credentials on the constructor
var spotifyApi = new SpotifyWebApi({
  clientId: 'myClientId',
  clientSecret: 'myClientSecret'
});

// Get an access token and 'save' it using a setter
spotifyApi.clientCredentialsGrant().then(
  function(data) {
    console.log('The access token is ' + data.body['access_token']);
    spotifyApi.setAccessToken(data.body['access_token']);
  },
  function(err) {
    console.log('Something went wrong!', err);
  }
);

// Set the credentials when making the request
var spotifyApi = new SpotifyWebApi({
  accessToken: 'njd9wng4d0ycwnn3g4d1jm30yig4d27iom5lg4d3'
});

// Do search using the access token
spotifyApi.searchTracks('artist:Love').then(
  function(data) {
    console.log(data.body);
  },
  function(err) {
    console.log('Something went wrong!', err);
  }
);

// Set the credentials when making the request
var spotifyApi = new SpotifyWebApi({
  accessToken: 'njd9wng4d0ycwnn3g4d1jm30yig4d27iom5lg4d3'
});

// Get tracks in a playlist
api
  .getPlaylistTracks('3ktAYNcRHpazJ9qecm3ptn', {
    offset: 1,
    limit: 5,
    fields: 'items'
  })
  .then(
    function(data) {
      console.log('The playlist contains these tracks', data.body);
    },
    function(err) {
      console.log('Something went wrong!', err);
    }
  );
