If you're a web developer interested in building scalable single-page applications--full-stack, browser-based apps that connect to a backend--this practical guide shows you how to use Ember.js, the popular JavaScript framework based on the model-view-controller (MVC) architectural pattern.Through the course of the book, you'll learn how to build a prototype Ember application (a musician index called Rock'n'Roll Call), using routers, templates, models, controllers, and views. You'll also understand how Ember's convention over configuration approach helps you persist data, build backend technologies, and create widgets for developing production-capable applications that behave like desktop software.Set up workflow management and boilerplate code creationLearn how Ember's "developer ergonomics" help you use less codeWrite templates for the book's prototype with Handlebars.jsUse routers to manage application states without reloading the pageConnect controllers and views with events, and sync data with data-bindingBuild an Ember backend with a RESTful API or Ruby on RailsUse the Ember-Data library to persist data and talk to the backendWrite reusable encapsulated widgets to extend your applications
