The book focuses on using Bidirectional streams Over Synchronous HTTP (BOSH) for empowering real-time communications over the web. The basic layout of an infrastructure to support such systems over current web technologies is dissected, and in so doing being one of the better discussions on the topic. This is helpful given the pushback many web devs typically have expressed in embracing a new technology stack.
The book is divided into 14 chapters that won't take you all day to read and follow along with. Each chapter is about 20-30 pages, intelligently written, logically organized and appropriately enhanced with URLs, illustrations, screengrabs and syntactical explanations to support the subject. Moffitt's voice is very friendly, and the chapters are long enough to give attention to the topic at-hand, but not drawn out to be boring. You can tackle each demo at a single sitting, run the code, and then expand upon it.
The appendices are also extremely helpful, focusing on introduction to the jQuery framework, and working with BOSH connection managers. Both are very concise and helpful (although I would have appreciated an additional appendix that gets more in-depth on working with Strophe).
As far as the book's physical qualities, the Wrox binding is sturdy with thick paper, so it'll survive the process of violently flipping back and forth and forcing the book to lie flat as you work through the examples.
It's a great read for anyone wanting to get up and running with XMPP for the web, and will make a very welcome addition to any developmental library.
That being said, I thoroughly enjoyed the author's presentation, and this was a standout book from Wrox for me, as they've improved the quality of their paper (thicker and now white), typesetting (smaller margins), and I suppose even the use of a graphic for the cover (as opposed to the author's picture) was well-received ...
The author is clearly well-versed in XMPP, and the introduction was very effective at getting me up to speed on using XMPP in an immediately sense. The chapters built upon one another in complexity, and I never felt lost, or had to re-read along the way.
Overall, I thought this book was effective, and the author's style made for an enjoyable read - one that wasn't terribly dry and at once didn't feel self-indulgent ...
In writing my first XMPP web application (which is actually my first XMPP application ever), this book has been extremely helpful. The beginning chapters give a thorough overview of the basics of XMPP, while the remaining chapters provide real-world walkthroughs of example XMPP web applications with well-commented, easy to understand source code.
Before I bought the book, I knew enough about XMPP to think that it might be a good fit for a project I'm working on. After reading the book, I felt well-informed about XMPP as an architecture and I was convinced that my web app would, indeed, be a perfect fit for using XMPP as its transport protocol. Thanks to the many code samples in the book, I was able to create a proof of concept of my web application, using XMPP for real-time communication, in only a few days. There's no way I could have gotten up to speed so quickly without this book.
It's also worth mentioning that the author is an extremely knowledgeable and active participant in the XMPP community. On his blog, [...], he shares many insights and tips about building XMPP web applications. It's a great supplement to this book and not to be missed.
I've been following jabber/XMPP for a few years now, looking at it as a potential technology for writing multiplayer games. 'Professional XMPP' is the book I've been waiting for. Jack deftly introduces the required subjects and follows up with very readable examples (code that works!).
If you're into mainstream web technologies you'll find his embrace of jQuery just right. You don't have to use it, but Strophe uses the same chaining methods that you probably already know.
This book will get you thinking about things that will trip up your app. It provides detailed, well commented examples which are downloadable from the publisher site.
If you are struggling to understand XMPP and create a chat client for your site, this book is an essential, which I highly recommend. In fact, I used many of the ideas found in the book to create DXMPP, a module for a Facebook-like chat client for Drupal. This book is definitely the go-to for web developers wanting to learn XMPP.
