node-twitter in express framework

I'm trying to use node-twitter module in express framework. I'm pretty new to node, I understand the basic routing, rendering jade templates and installing packages and etc. But I'm very happy to see so many packages out there, but when I get in to the details I don't really understand how to use them in express framework.

Currently, I'm using node-twitter module (https://github.com/desmondmorris/node-twitter) and would like to use Streaming API. Below are the code snippets which I would need to get started with streaming API. I've got all the required keys and stuck when it comes to express. So; my question is, how to pass this to a route?

var util = require('util'),
    twitter = require('twitter');
var twit = new twitter({
    consumer_key: '',
    consumer_secret: '',
    access_token_key: '',
    access_token_secret: ''
});


twit.stream('user', {track:'nodejs'}, function(stream) {
    stream.on('data', function(data) {
        console.log(util.inspect(data));
    });
    // Disconnect stream after five seconds
    setTimeout(stream.destroy, 5000);
});

As far as I know, there are two ways of routing, one is rendering a template and other one is directly sending a response.

app.get('/',function(req, res){
res.render ('index');
});

app.get('/test',function(req,res){
res.send('this is a test');
})

Now, how set up routes for twitter streaming api? please advice.
