title: NodeJS - MongoDB triggers
body: <p>I'm trying to develop a Log Viewer using DerbyJS, Racer and MongoDB. The logs will be inserted into the MongoDB database by a different source continuously, and my Log Viewer should be able to update the Logs Table on the user interface automatically.</p>
  
  <p>I was wondering if there is a native way of listening to MongoDB events, like:</p>
  
  <pre><code> - On update
   - On delete
  </code></pre>
  
  <p>These would be similar to, for example, Oracle DB triggers.</p>
