<p>Backbone.js is an open source, JavaScript library that helps you to build sophisticated and structured web apps. It's important to have well-organized frontend code for easy maintenance and extendability. With the Backbone framework, you'll be able to build applications that are a breeze to manage.<br /><br />In this book, you will discover how to build seven complete web applications from scratch. You'll learn how to use all the components of the Backbone framework individually, and how to use them together to create fully featured applications. In addition, you'll also learn how Backbone thinks so you can leverage it to write the most efficient frontend JavaScript code.<br /><br />Through this book, you will learn to write good server-side JavaScript to support your frontend applications.

Creating our application navigation


We've already got a basic version of this from the template. However, we need to adjust the script tags at the bottom. After the tag for backbone.js, but before the tag for app.js, you'll want to add the following line:

<script>var USER = <%- user %>;</script>

This is the user object that is the user that is currently logged in. We'll need to be able to work with some of its properties inside our application components, which is why we need to load it before the app.js file.

Speaking of the app.js file, that's our next stop. This time, we're going to begin with a router:

var AppRouter = Backbone.Router.extend({
  initialize: function (options) {
    this.main = options.main;
    this.navView = new NavView();
  },
  routes: {
    '': 'index'
  },
  index: function () {
    this.main.html(this.navView.render().el);
  }
});

This is very similar to the router from our previous application. Any options—such as DOM elements, models, or collections...
