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.

Learning the Ember run loop


The Ember run loop is an extremely important part of Ember's internals. The run loop is used to batch, order, and work in a way that's most efficient for the Ember application. In this recipe, we'll create a simple timer and take a look at how the run loop works.

Getting ready

Before we move on to our recipe, we'll need to understand some basics of the Ember run loop.

Understanding Ember run queues

The Ember run loop consists of six queues as follows:

  • sync: This queue consists of binding synchronization jobs.

  • actions: This queue contains general work and promises.

  • routerTransitions: This queue contains transition jobs in the router.

  • render: This queue contains jobs meant to render, usually to update the DOM.

  • afterRender: This queue is run after all previously scheduled render tasks are completed. This queue is typically used for third-party applications.

  • destroy: This last queue tears down objects.

These queues don't run all the time. They only run in response to certain...
