We have submitted the drafts of four chapters of the book “Enterprise Web Development: from Desktop to Mobile” to O’Reilly for review and editing. This is a pretty hands-on book as we are developing an application Save Sick Child while explaining various techniques and technologies. The readers will get a new independent working application every time we add a new piece of functionality (e.g. login, donation form, video, Google maps, charts, auction, etc.). These projects will be published on the dedicated Web site savesickchild.org. For example, this is a sample application illustrating modularization of the JavaScript-based UI.
The following chapters are submitted to the publisher, but the raw texts are available for you to read now on the github at https://github.com/Farata/EnterpriseWebBook:
Chapter 2. Advanced Intro to JavaScript
Chapter 3. Mocking up Save Sick Child
Chapter 4. Using AJAX and JSON
Chapter 9. Replacing HTTP with WebSockets
Currently we are working on the chapters on responsive design, test-driven development and modularization of the JavaScript applications. We’re making these unpolished chapters available for you to read hoping to get valuable technical feedback from you. Please do let us know if you see some bugs or inefficient solutions in the code samples. We really really appreciate it.

What’s the difference between the github repo and http://enterprisewebbook.com?
Github stores the sources in asciidoc format, code snippets, and images, But enterprisewebbook.com is our own web site where we generate and publish the readable HTML from the github sources. Every time we push some new content to github, we run a script that builds HTML and publishes it on enterprisewebbook.com.
