Introduction to Backbone.js Part 3: Routers – Video Tutorial

We’re on to part 3 in the Backbone.js video tutorials series. This week we feature another important piece of the Backbone puzzle: Routers. You could conceivably create your JavaScript apps without Routers, but the ingenious technique behind routers allows your users to bookmark the app at a particular state or even use the back and forward buttons to traverse through the history of your applications state. Watch the video to learn more!

var Router = Backbone.Router.extend({
    routes: {
        "foo/:bar" : "paramtest",
        "*action" : "func"
    },
    func: function (action) {
        console.log(action);
    },
    paramtest:function (p) {
        console.log(p);
    }
});

new Router();

Backbone.history.start();

Conclusion

As stated in the video, I’m sorry for the delay. At least you’ll be seeing two videos this week, though! On Thursday (at least I hope it’s on Thursday) Part 4: Collections should be released. Also, contrary to the itinerary I gave in part 2, I’ve decided to do one more tutorial before taking a break and then starting up the app. Part 5 will contain a tutorial on using AJAX to populate your models. I won’t say whether this comes out next Monday or Thursday, so you’ll just have to wait and find out. In the meantime, keep studying up on the parts 1 through 3 until you feel confident (which shouldn’t take too long).
