Plangular

Angular directive for custom SoundCloud players jxnblk.com/plangular

Getting Started

npm install plangular-3

Or install with Bower:

bower install plangular

Or use the CDN:

<script src="http://d2v52k3cl9vedd.cloudfront.net/plangular/3.1.0/plangular.min.js"></script>

Angular app

Include a link to plangular after including Angular.

<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
<script src="bower_components/plangular/dist/plangular.min.js"></script>

Initialize the app

Configure Plangular with your own client_id. For new SoundCloud apps, you can register at https://developers.soundcloud.com/

<body ng-app="app">
 
  <script>
    var app = angular.module('app', ['plangular'])
      .config(function(plangularConfigProvider){
        plangularConfigProvider.clientId = '[YOUR-CLIENT-ID]';
      });
  </script> 
</body>

Create a plangular directive instance

<div plangular="http://soundcloud.com/jxnblk/plangular">
</div>

Include track info

<div plangular="http://soundcloud.com/jxnblk/plangular">
  <h3>{{track.user.username}} - {{track.title}}</h3>
  <a ng-href="{{track.permalink_url}}">View on SoundCloud</a>
</div>

Add player controls

<button ng-click="playPause()">Play/Pause</button>

Or with separate play/pause controls:

<button ng-click="play()">Play</button>
<button ng-click="pause()">Pause</button>

Show current time and duration

Use the hhmmss filter to format seconds as hh:mm:ss strings.

<small>{{ currentTime | hhmmss }} | {{ duration | hhmmss }}</small>

Progress bar

<progress ng-value="currentTime / duration || 0">
  {{ currentTime / duration || 0 }}
</progress>

Add scrubber functionality

<progress
  ng-click="seek($event)"
  ng-value="currentTime / duration">
  {{ currentTime / duration }}
</progress>

Add images

<img ng-src="{{ track.artwork_url  }}" alt="{{ track.title }}" />
<img ng-src="{{ track.waveform_url }}" alt="waveform" />

Note: The waveform image that the SoundCloud API provides is a 1200 x 280px PNG with a light gray frame and transparent middle. To show progress use absolute positioning with the waveform in front. The light gray color is #efefef.

Loading states

Use the ng-if directive to show and hide content based on whether the track has loaded.

<div ng-if="!track"><!-- Loading state --></div>
<div ng-if="track"><!-- Player --></div>

Playlists

Use the tracks array and ng-repeat when using a SoundCloud playlist. Pass the $index to the playPause() method to trigger playback on a per-track basis. Determine which track is currently playing with player.playing === track.src.

<ul>
  <li ng-repeat="track in tracks">
    <button
      ng-click="playPause($index)"
      ng-class="{'active': player.playing === track.src}">
      {{track.user.username}} - {{track.title}}
    </button>
  </li>
</ul>

User tracks

To load the most recent tracks from a given user, use the tracks endpoint. Use ng-repeat to iterate over the tracks array.

<div plangular="http://soundcloud.com/jxnblk/tracks">
</div>

User likes

To load the most recent likes from a given user, use the likes endpoint.

<div plangular="http://soundcloud.com/jxnblk/likes">
</div>

Previous/next controls

To skip to the next and previous track in a playlist or array of tracks, use the previous() and next() methods.

<button ng-click="previous()">Previous</button>
<button ng-click="next()">Next</button>

For more details on the SoundCloud track object, see https://developers.soundcloud.com/docs/api/reference#tracks

Troubleshooting

SoundCloud provides an option for users to prevent streaming to third-party apps. If your sound isn't playing check the track.streamable variable. If it's set to false, there is no way to play that sound with the API.
