Book Review : Learning Ext JS 4

The folks at Packt asked me to review another of their book on Learning EXTJS 4 If you are interested in buying it (a judgment you may reserve until after you have read the review)EXTJS4 is on packt site
this is link you can go.Learning EXtJs 4 is on packt site

Crysfel Villa ,Armando Gonzalez are author of this book.Crysfel Villa is a Software Engineer with more than 7 years of experience with JavaScript on a daily basis.Armando Gonzalez is a Software Engineer with more than 4 years of experience
in developing enterprise applications with Ext JS. He has plenty of experience in
server-side technologies like PHP, Java J2EE, Node JS, and ROR.

The first thing you will probably notice is the size of the document. This is no brief summary of the new features. This is small book of over 40 pages covering to learn a new java script librart with a full index in the back. The structure of the book is:
Business overview

Step 1 – The Basics
Step 2 – The Core Concepts
Step 3 – Components and Layouts
Step 4 – It’s All About the Data
Step 5 – Buttons and Toolbars
Step 6 – Doing it with Forms
Step 7 –Give me the Grid
Step 8 – Architecture

Step 13- From Drawing to Charting

I like this structure as it parallels the steps one would take in setting up a EXTJS 4. To add a bit of a flow to the book, they also put it in the examples,real life scenarios.

Its more a starter book.This book focuses on giving the reader a firm understanding of the core concepts of EXTJS, such as Drag and Drop and tree panel, and works through real-life app development scenarios. All core components of EXTJS’s amazing library are covered in detail, and strategies are outlined for getting the best use of time when developing with EXTJS.

Few components which i like to mention , which i enjoy reading alot – a clear explanation of how to make drag drop using EXTJS.
How tree panel compoenent work.How you can make charts components for example pie,bar , gauage. Skinning of application is well defined.

OVer all i can say this book for beginner.Few new features which is added in EXT JS 4 is added and describe well.A must purchase for those who want to learn EXT JS 4. You can also download the code which is available with the book

Happy coding with Techartifact and packt….

Book Review : Ext JS 4 First Look

The folks at Packt asked me to review one of their book on EXTJS 4 If you are interested in buying it (a judgment you may reserve until after you have read the review)

“” this is link you can go

Loiane Groner iS a EXT-JS consultant, she is expert in EXT JS. As far as I can recall, I have never met them but I follow her blog regularly

The Packt model is an interesting one. They are an online publishing house who approach subject matter experts and offer them an advance and a good commission for writing a book for them. They have approached me a couple of times but I have turned them down on both occasions simply due to a lack of time. Given the movement towards e-readers and related devices I believe it is a business model most publishers will eventually adopt.

Overview and Structure of the Book

The first thing you will probably notice is the size of the document. This is no brief summary of the new features. This is over 340 pages covering what has changed since EXT JS 3 in EXT JS 4 with a full index in the back. The structure of the book is:

• The usual preliminary bits (About the Authors, Acknowledgement, Table of Contents etc.)
• Chapter 1: What new in EXT JS 4.
• Chapter 2: The new Data package
• Chapter 3: Upgraded Layout
• Chapter 4: Upgraded Charts
• Chapter 5: Upgraded Grid, Tree and Form
• Chapter 6: Ext JS 4 Themes
• Chapter 7: MVC Application Architecture
• Appendix
• Index

I like this structure as it parallels the steps one would take in setting up a EXT JS4. The titles are also plain English e.g. ‘Ext JS 4 First Look’ making it easier to know where to go. To add a bit of a flow to the book, they also put it in the examples,real life scenarios
What is missing is – This book is not for the beginners who are learning EXT JS from scratch. Major feature release.
Ext JS 4 introduces major changes compared to Ext JS 3..You will find lot of changes There is a new data package, new charts, and new, updated layouts. The framework was completely changed from EXT JS 3 for increasing the performance.
This book covering all changes in EXT JS 4 , all new features using coding example with detailed explanation and screenshot of code as well the result too. Book will make you understand the changes in EXT JS 4 with presented examples and using this book you can easily migrate the application from EXT JS 3 to EXT JS 4 application

Chapter 1: What’s New in Ext JS 4

This chapter provides an introduction to all major changes between Ext JS 3 and Ext JS 4. Ext JS 4 presents a vast improvement in all packages; the framework was completely rewritten to boost performance and make learning and configuring easy. This chapter covers all these changes, from class system, to an overview, to the new Sencha platform
Good high-level review to introduce the reader to these completely new features

Chapter 2: The New Data Package

This chapters covers all the changes in the data packageI am amazed to see the Sencha Touch framework for mobile application This chapter introduces the new Model class, associations, proxies, operations, batches, and the new features of the Store class.
What this means is the book lends itself to system architects with a good understanding of the configuration options of the system but not so much to people who are new to either system.

Chapter 3: Upgraded Layouts

This is a great chapter on the awesome work Sencha Team has done on improving the layout. It covers all changes made to the existing layouts, and the new component layout engines, such as dock, toolbar, field, and trigger field layouts. It also covers the changes made to the container layouts, such as fit, border, table, anchor, card, accordion, and so on..
If you are stuck in designing the layout of application then reading this chapter is worth of. 

Chapter 4: Upgraded Charts

I like this chapter after reading this a lot. Chapters presents the new JavaScript-powered Ext JS 4 charts. And what you can expect more the no flash is required anymore. This chapter introduces the new draw package, which is the base package for the new chart package. It also covers how to configure chart axis, legend, customized themes, and Ext JS 4 chart series, such as Bar, Column, Line, Area, Scatter, Pie, Radar, and Gauge.

Chapter 5: Upgraded Grid, Tree, and Form

Again, this is a big topic for one chapter. It mention and demonstrates the upgraded Ext JS Components. Very well explained the more performance and more developer flexibility. Some new features and plugins for Components covered in this chapter are: grid, tree, and forms.

Chapter 6: Ext JS 4 Themes

This is probably one of the best example or step by step way of creating on how developer can customize and create a new theme by using CSS architecture, which uses Sass and Compass.

Chapter 7: MVC Application Architecture

. One nice touch in this chapter how MVC architecture applied or implemented to Ext JS 4 applications. This chapter as with others is designed to give the reader a feel for creating a MVC EXT JS 4 application. Steps by steps instruction given in this chapter. Chapter also includes the structure of EXT JS 4 application project structure and how reader can manage the component, files in EXT project structure.
Appendix A, Ext JS 4 Versus Ext JS 3 Class Names,
It presents a comparison list between Ext JS 3 classes and Ext JS 4 class names. In this new version of Ext JS, the names of some classes have changed, and this list can help you find the new Ext JS 4 class names easily, while migrating an application from Ext JS 3 to Ext JS 4 Beta.


This book is not a comprehensive guide to the learn EXT JS 4 or EXT JS. Rather, it is an introduction to some of the new features of the product, compared to EXT JS 3. .It is good guide if you want to migrate an application from EXT JS 3 to EXT JS 4 or if you want learn ,understand the new feature and advanced topic on EXT JS 4.The way author mentioned he pseudo code with example and detailed description is really good. Features of the product they do cover are covered very well. What I mean by this is their high-level summaries of large topics, such as Layout ,tree and form, cover the essential elements and their treatment of smaller topics, such as EXT JS 4 Theme, MVC Application Architecture topic are some of the best I have seen.

While there is not as much bang for buck as, say, Loiane Groner’s book, the EXT JS 4 developer will not have to filter out a rehash of the version 4 features as this book assumes that knowledge. Where I see this book working is as good migration guide. While those volumes allow the reader to drill down into a specific topic, this book, uniquely, gives a much greater context to the features in question, providing a practical example as an integral part of the narrative
