title: azure documentdb trigger for push notification
body: <p>I need to call push notifications from my trigger but I need to do the following:</p>
  
  <pre><code>var azure = require('azure');
  var notificationHubService = azure.createNotificationHubService("","");
  </code></pre>
  
  <p>But I am getting the following:</p>
  
  <blockquote>
    <p>executing Javascript. Exception = ReferenceError: 'require' is
    undefined</p>
  </blockquote>
  
  <p>Is there another way to accomplish this, can I import node.js libraries?</p>
