Usage

Ruby

To use with ruby gem, add this code to your initializer:

Pusher.host = 'localhost'
Pusher.port = 8081
Pusher.app_id = 'appid1'
Pusher.key = 'key1'
Pusher.secret = 'secret1'

JavaScrpit

To use with javascript client, add host and ws_port params to your code:

<script src="http://js.pusher.com/2.0/pusher.min.js"></script>
<script type="text/javascript">
  Pusher.log = function(data) {
    console.log('\t\t', data);
  };
  Pusher.host    = "127.0.0.1";
  Pusher.ws_port = "8081";
  var pusher = new Pusher('key1');
  pusher.bind('pusher:error', function(data) { console.log(data.to_json) })
  var myChannel = pusher.subscribe('MY_CHANNEL');
  myChannel.bind('an_event', function(data) { console.log(data) })
</script>

If you want to use Pusher 2.0 js library you need to set stats_host, sockjs_host and sockjs_port:

<script src="http://js.pusher.com/2.0/pusher.min.js"></script>
 <script type="text/javascript">
  Pusher.log = function(data) {
    console.log('\t\t', data);
  };
  Pusher.host    = "127.0.0.1";
  Pusher.ws_port = "8081";
  Pusher.stats_host = '127.0.0.1:8081';
Pusher.sockjs_host = 'localhost';
Pusher.sockjs_http_port = '8081';
Pusher.disableStats = true;
  var pusher = new Pusher('key1');
  pusher.bind('pusher:error', function(data) { console.log(data.to_json) })
  var myChannel = pusher.subscribe('MY_CHANNEL');
  myChannel.bind('an_event', function(data) { console.log(data) })
</script>
