Ember.js Cookbook

By: Erik Hanchett

Overview of this book

Ember.js is an open source JavaScript framework that will make you more productive. It uses common idioms and practices, making it simple to create amazing single-page applications. It also lets you create code in a modular way using the latest JavaScript features. Not only that, it has a great set of APIs to get any task done. The Ember.js community is welcoming newcomers and is ready to help you when needed. This book provides in-depth explanations on how to use the Ember.js framework to take you from beginner to expert. You’ll start with some basic topics and by the end of the book, you’ll know everything you need to know to build a fully operational Ember application. We’ll begin by explaining key points on how to use the Ember.js framework and the associated tools. You’ll learn how to effectively use Ember CLI and how to create and deploy your application. We’ll take a close look at the Ember object model and templates by examining bindings and observers. We’ll then move onto Ember components, models, and Ember Data. We’ll show you examples on how to connect to RESTful databases. Next we’ll get to grips with testing with integration and acceptance tests using QUnit. We will conclude by covering authentication, services, and Ember add-ons. We’ll explore advanced topics such as services and initializers, and how to use them together to build real-time applications.

Working with classes and instances


Creating and extending classes is a major feature of the Ember object model. In this recipe, we'll take a look at how creating and extending objects works.

How to do it...

  1. Let's begin by creating a very simple Ember class using extend():

    const Light = Ember.Object.extend({
      isOn: false
    });

    This defines a new Light class with a property called isOn. Light inherits properties and behavior from the Ember object, such as initializers, mixins, and computed properties.

    Ember Twiddle tip

    At any point of time, you might need to test out small snippets of the Ember code. An easy way to do this is to use a website called Ember Twiddle. From this website, you can create an Ember application and run it in the browser as if you were using the Ember CLI. You can even save and share it. It has similar tools such as JSFiddle but only for Ember. Check it out at http://ember-twiddle.com.

  2. Once you have defined a class, you'll need to be able to create an instance of it. You...
