Adding a simple GET request support is fairly simple, and you've seen this before already in the app we built. Here is some sample code that responds to a GET request and returns a simple JavaScript object as JSON. Insert the following code in the routes section where we have the // TO DO: Setup endpoints ... waiting comment:

router.get('/test', function(req, res) {
    var data = {
        name: 'Jason Krol',
        website: 'http://kroltech.com'
    };

    res.json(data);
});

Just like we set up viewModel in Chapter 5, Dynamic HTML with Handlebars, we create a basic JavaScript object that we can then send directly as a JSON response using res.json instead of res.render. Let's tweak the function a little bit and change it so that it responds to a GET request against the root URL (that is /) route and returns the JSON data from our movies file. Add this new route after the /test route added previously:

router.get('/', function(req, res) {
    res.json(json);
})...
