Ext JS 4 design conventions and concepts

The Sencha Ext JS 4 team has done an enormous amount of work in defining conventions, which you should consider following, for building enterprise applications. These include a standard directory structure, naming conventions, and detailed design best practices. We strongly urge you to browse the many tutorials and guides on the Sencha Ext JS 4 Docs website at http://docs.sencha.com/extjs/4.2.2 to become familiar with their application design recommendations.

This book will adhere to the common design strategies outlined by the Ext JS 4 team, with minor differences noted and explained upon being introduced in their relevant sections. It is beyond the scope of the book to cover basic Ext JS 4 concepts and you may need to refer to the Sencha Ext JS 4 Docs to fine-tune your understanding.
