title: socket.io with express
body: <p>i have a project and I'm using socket.io with express ,</p>
  
  <p>so what i need (i tried) is broadcasting a message but from an express action.
  is this possible i don't know how to get a reference to send or broadcast.</p>
  
  <pre><code>app.get('/', function(req, res) {
  //i need to send messages from here 
  });
  </code></pre>
