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.

Loading and error handling

When routes are loading or there's an error, we have the ability to let the user know what's happening. This recipe will go over the basics on how to do this.

How to do it...

In a new project, create a new students route:
```
$ ember g route students
```
The ember generate command will create all the necessary files for the students route.
Edit the students.js file in the app/routes folder. Add a new model to return:
```
// app/routes/students.js

export default Ember.Route.extend({
    model(){
      return new Ember.RSVP.Promise(function (resolve, reject) {

      });
    }
});
```
In our route file, we are returning an Ember RSVP promise. This promise resolves to a simple array that will be returned. Ember.run.later is a built-in Ember method that is a part of the Ember run loop. It acts like the JavaScript's setTimeout(). In this case, we are setting the timeout...
