# Spotify Web API Node [![Tests](https://travis-ci.org/thelinmichael/spotify-web-api-node.svg?branch=master)](https://travis-ci.org/thelinmichael/spotify-web-api-node) [![Coverage Status](https://coveralls.io/repos/thelinmichael/spotify-web-api-node/badge.svg)](https://coveralls.io/r/thelinmichael/spotify-web-api-node) [![npm bundle size (minified + gzip)](https://img.shields.io/bundlephobia/minzip/spotify-web-api-node.svg)](https://bundlephobia.com/result?p=spotify-web-api-node) This is a universal wrapper/client for the [Spotify Web API](https://developer.spotify.com/web-api/) that runs on Node.JS and the browser, using [browserify](http://browserify.org/)/[webpack](https://webpack.github.io/)/[rollup](http://rollupjs.org/). A list of selected wrappers for different languages and environments is available at the Developer site's [Libraries page](https://developer.spotify.com/web-api/code-examples/). Project owners are [thelinmichael](https://github.com/thelinmichael) and [JMPerez](https://github.com/JMPerez), with help from [a lot of awesome contributors](https://github.com/thelinmichael/spotify-web-api-node/network/members). ## Table of contents * [Features](#features) * [Installation](#installation) * [Usage](#usage) * [Development](#development) ## Features The library includes helper functions to do the following: #### Music metadata * Albums, artists, and tracks * Audio features and analysis for tracks * Albums for a specific artist * Top tracks for a specific artist * Artists similar to a specific artist #### Profiles * User's emails, product type, display name, birthdate, image #### Search * Albums, artists, tracks, and playlists #### Playlist manipulation * Get a user's playlists * Create playlists * Change playlist details * Add tracks to a playlist * Remove tracks from a playlist * Replace tracks in a playlist * Reorder tracks in a playlist #### Your Music library * Add, remove, and get tracks and albums that are in the signed in user's Your Music library * Check if a track or album is in the signed in user's Your Music library #### Personalization * Get a user’s top artists and tracks based on calculated affinity #### Browse * Get New Releases * Get Featured Playlists * Get a List of Categories * Get a Category * Get a Category's Playlists * Get recommendations based on seeds * Get available genre seeds #### Follow * Follow and unfollow users * Follow and unfollow artists * Check if the logged in user follows a user or artist * Follow a playlist * Unfollow a playlist * Get followed artists * Check if users are following a Playlist #### Player * Get a user's available devices * Get information about the user's current playback * Get current user’s recently played tracks * Transfer a user's playback * Resume a user's playback * Skip a user's playback to next track * Skip a user's playback to previous track * Set a user's shuffle mode * Set a user's repeat mode * Set volume * Seek playback to a given position All methods require authentication, which can be done using these flows: * [Client credentials flow](http://tools.ietf.org/html/rfc6749#section-4.4) (Application-only authentication) * [Authorization code grant](http://tools.ietf.org/html/rfc6749#section-4.1) (Signed by user) ##### Dependencies This project depends on [superagent](https://github.com/visionmedia/superagent) to make HTTP requests, and [promise](https://github.com/then/promise) as its [Promises/A+](http://promises-aplus.github.io/promises-spec/) implementation. ## Installation $ npm install spotify-web-api-node --save ## Usage First, instantiate the wrapper. ```javascript 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. ```javascript 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. ```javascript // 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. ```javascript // 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 currently **required if you're using callback methods**. ```javascript // 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); } ); ``` ### Response body, statuscode, and headers 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 ```json { "body" : { }, "headers" : { }, "statusCode" : } ``` In previous versions, the response object was the same as the response body. #### Example of a response Retrieving a track's metadata in `spotify-web-api-node` version 1.4.0 and later ```json { "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 } ``` The response object for the same request in earlier versions than to 2.0.0. ```json { "name": "Golpe Maestro", "popularity": 42, "preview_url": "https://p.scdn.co/mp3-preview/4ac44a56e3a4b7b354c1273d7550bbad38c51f5d", "track_number": 1, "type": "track", "uri": "spotify:track:3Qm86XLflmIXVm1wcwkgDK" } ``` ### More examples Below are examples for all helper functions. Longer examples of some requests can be found in the [examples folder](examples/). 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. ```javascript var SpotifyWebApi = require('spotify-web-api-node'); var spotifyApi = new SpotifyWebApi(); // Get multiple albums spotifyApi.getAlbums(['5U4W9E5WsYb2jUQWePT8Xm', '3KyVcddATClQKIdtaap4bV']) .then(function(data) { console.log('Albums information', data.body);

}); }) .then(function(albums) { return spotifyApi.getAlbums(albums); }) .then(function(data) { console.log(data.body); }); ``` ### Authorization 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](https://developer.spotify.com/spotify-web-api/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.** The first thing you need to do is to [create an application](https://developer.spotify.com/my-applications/). A step-by-step tutorial is offered by Spotify in this [tutorial](https://developer.spotify.com/spotify-web-api/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](https://developer.spotify.com/spotify-web-api/using-scopes/). 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. ```javascript 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. ```javascript 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. ```javascript // 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. ```javascript 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); } ); ``` #### 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. ```javascript // 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. ```javascript // 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); } ); ``` ```javascript // 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); } ); ``` ```javascript // Set the credentials when making the request var spotifyApi = new SpotifyWebApi({ accessToken: 'njd9wng4d0ycwnn3g4d1jm30yig4d27iom5lg4d3' }); // Get tracks in a playlist api .getPlaylistTracks('thelinmichael', '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); } ); ``` ## Development See something you think can be improved?
