As more and more of our work is done through a web browser, and more businesses build web rather than desktop applications, users want web applications that look and feel like desktop applications. Ext JS is a JavaScript library that makes it (relatively) easy to create desktop-style user interfaces in a web application, including multiple windows, toolbars, drop-down menus, dialog boxes, and much more. Both Commercial and Open Source licenses are available for Ext JS.

Ext JS has the unique advantage of being the only client-side UI library that also works as an application development library. Learning Ext JS will help you create rich, dynamic, and AJAX-enabled web applications that look good and perform beyond the expectations of your users.

From the building blocks of the application layout, to complex dynamic Grids and Forms, this book will guide you through the basics of using Ext JS, giving you the knowledge required to create rich user experiences beyond typical web interfaces. It will also provide you with the tools you need to use AJAX, by consuming server-side data directly into the many interfaces of the Ext JS component library.

What you will learn from this book?

  • Create responsive forms
  • Look at Web Applications from an entirely new perspective
  • Learn to use the major UI components available in Ext JS
  • Understand how external data can be consumed by Ext JS
  • Query and process remote data into your application
  • Use Layouts to bring all of the Ext JS pieces together
  • Use Ext JS effects to manipulate the DOM in exciting ways
  • Provide a consistent look and feel to your application using Components
  • Change the visual style of Ext JS using theming support
  • Find Custom Community Extensions to expand your applications
  • Create your own custom library extensions


The book provides plenty of fun example code and screenshots to guide you through the creation of examples to assist with learning. By taking a chapter-by-chapter look at each major aspect of the Ext JS framework, the book lets you digest the available features in small, easily understandable, chunks, allowing you to start using the library for your development needs immediately.

Who this book is written for?

This book is written for Web Application Developers who are familiar with HTML but may have little to no experience with JavaScript application development. If you are starting to build a new web application, or are re-vamping an existing web application, then this book is for you.
