Preface

If you are an Ext JS developer, it probably took you a while to learn the framework. We know that the Ext JS learning curve is not short. After we have learned the basics, and we need to use Ext JS in our daily jobs, a lot of questions pop up: how can one component talk to another? What are the best practices? Is it really worth using this approach and not another one? Is there any other way I can implement the same feature? This is normal.

This book was written thinking about these developers.

So this is what this book is about: how do we put everything together and create really nice applications with Ext JS? We are going to create a complete application, from the mockup of the screens all the way to putting it into production. We are going to create the application structure, a splash screen, a login screen, a multilingual capability, an activity monitor, a dynamic menu that depends on user permission, and modules to manage database information (simple and complex information). And then, we will learn how to build the application for production, how to customize the theme, and how to debug it.

We will use real-world examples and see how we can implement them using Ext JS components. And throughout the book, we've also included a lot of tips and best practices to help you boost your Ext JS knowledge and take you to the next level.
