Chapter 1, Sencha MVC Architecture: This chapter describes the MVC architecture and outlines the need of having an MVC architecture implemented on the clientside, which runs inside a browser. The chapter shows how to model an application without using Sencha MVC architecture and look at the demerits of that modeling. It then reviews the benefits that one can get by following Sencha MVC architecture. Subsequently, it visits the classes in ExtJS as well as Sencha Touch, which map to the model, view, and controller.

Chapter 2, Creating an Application: In this chapter we look at a sample application and learn how to model it as per the MVC architecture and map the different building blocks to the classes provided by ExtJS and Sencha Touch. The application development involves how to identify the views, models, and controllers in an application, how to make use of multiple controllers within an application and pass the data and control between them to achieve the overall application behavior. At the end, we look at some of the rules related to class naming convention, folder structure, and so on, which is required to get the application up and running.

Chapter 3, Building Blocks: This chapter covers the different classes, which are part of the MVC architecture in ExtJS as well as Sencha Touch. It covers the function of each of these classes and the differences in their behavior and usage. In addition to the common classes—Application, Controller, Model, View (Component)—it also covers the Touch-specific way to handle profiles to encapsulate device-specific behaviors and layout in the applications. Also, it shows how to set up the routes in Touch application and have the history tracking in place.

Chapter 4, Class System: This chapter explains how the new class system works and what are the functionalities offered by the class system. It also covers what are the naming conventions put in place and recommended by the framework, how to define classes, set up dependencies, implement inheritance, enhance capability using mixins, create singleton classes, and so on.

Chapter 5, Challenges and Solutions: This chapter reviews some of the main challenges when it comes to developing an MVC-based application – project creation, build, debugging, and packaging. With the challenges at hand, the chapter then covers the Sencha SDK Tools to show how this tool can help us address each of those challenges.

To run the examples in this book you will need the following software:

This book is for someone who wants to understand the Sencha ExtJS and Touch frameworks, in general, and the Sencha MVC Architecture, in specific, to create scalable and maintainable applications. The book provides a complete end-to-end implementation of an application using the Sencha ExtJS as well as Sencha Touch frameworks by applying the Sencha MVC Architecture. The book is also useful for someone who wants to understand how the Sencha SDK Tools work and how one can set up an effective project management through project setup and build management.

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "Profile functionality is offered by the Ext.app.Profile class."

A block of code is set as follows:

{
  success: true,
  users: [
    {id: 1, name: 'Sunil',  email: '[email protected]'},
    {id: 2, name: 'Sujit', email: '[email protected]'},
    {id: 3, name: 'Alok', email: '[email protected]'},
    {id: 4, name: 'Pradeep', email: '[email protected]'},
    {id: 5, name: 'Ajit', email: '[email protected]'}
  ]
}

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Create a Dynamic Web Project workspace in Eclipse".
