Shea has spent the majority of his career in web development and first began developing web applications for Tower Records that combined the call center interface with inventory and fulfillment. Since then, Shea has worked as a developer for several companies - building and implementing various commerce solutions, content management systems, and lead tracking program. Integrating new technologies to make a better application has been a driving point for Shea's work. He strives to use open source libraries as they are often the launching pad for the most creative technological advances. He has worked closely with the ExtJS creators since inception to create cutting edge web interactivity and has contributed to its growth by writing documentation, tutorials, example code and a book for Packt. He has remained an active community member for the modern yui-ext library - ExtJS. On the rare occasion he's away from his keyboard, you can find him mountain biking or skiing.
I bought the first edition of this book for a project and because of the quality and the addition of more ColdFusion examples picked up this edition. It provides a great overview and supplement to the Ext API documentation with plenty of examples of implemented most of the functionality of Ext (now Sencha). Ext is a deep Javascript framework that is fairly easy to get started with but also a pretty steep learning curve for more complex applications and this book will take you pretty far down the road to mastery.
Looking forward to an advanced book that is similar in quality but that provides a more in depth example of how to architect a complex application using the library.
I like this book. It has some great examples and is well written. My complaint about it is that it doesn't really start from the ground up with JavaScript. I'm pretty comfortable with programming. This is not my first language, but there is something about JavaScript. I think it's how they do bracketing. It just doesn't click with me, and the book just kind of jumped in on code. I was able to decipher by example, but sometimes it's just nice to have that soft start and quickly ramp up.
Most revision 2's of books I've read are just a little cleaning up and republishing the same stuff just to make some more money. These guys, really put a lot of new material here covering much of what was missing from the first book (partly because it was not out yet in the earlier versions of ExtJS). Things like Ext.Direct and graphing are new and covered well.
