Imagine a true thin-client web application environment, with no browser incompatibilities, no plugins, and an interface that’s closer to a desktop app. You can have it all, today. Welcome to The Dojo Toolkit.

Mastering Dojo walks you through the whole range of modern web programming problems, from bringing simple web pages to life with widgets and animation, to designing and building an enterprise-class, single-page Rich Internet Application (RIA).

Are your web pages becoming more and more complex, with hundreds of lines of sprawling JavaScript as clients demand modern Ajax designs? Or maybe you’re about to enter the new world of single-page, Rich Internet Applications? Dojo is the unified toolkit that you need to get the job done.

VERSIONS: Applicable for Dojo Versions 1.1 to 1.7. Versions 1.2 onward contain additional widgets, experimental api’s and bugfixes. Please see the Dojorelease notes for detailed information.

About This Book

The last couple of years have seen big changes in server-side web programming. Now it’s the client’s turn; Dojo is the toolkit to make it happen and Mastering Dojo shows you how.

Dojo is a set of client-side JavaScript tools that help you build better web applications. Dojo blurs the line between local, native applications and browser-based applications; the browser becomes the user interface platform. “Modern” browsers provide an incomplete, inconvenient, and incompatible programming environment, but Dojo eliminates these problems. While there are many JavaScript libraries available, most focus on just one thing (for example, effects libraries, perceived JavaScript omissions, or HTML widgets). Dojo addresses all of these functional areas—and many others—extensively.

In Mastering Dojo, you’ll get the whole story, from basic usage to advanced idioms. Mastering Dojo starts out with a fast moving tutorial that will give you techniques that you can start using right away. You’ll learn all about Dojo Core—the foundation on which all things Dojo stand. See how you can modularize your project for development and automatically package your release for optimal download performance. You’ll also learn how Dojo:

  • augments the core JavaScript library
  • fixes the event system
  • simplifies DOM programming
  • provides a complete class definition facility
  • includes a powerful remote scripting (XHR) framework
  • ... and much more.

You’ll love using Dojo’s HTML user interface control widget system, Dijit. See how to use over 40 widgets, including the rich yet easy-to-use tree and grid controls.

Finally, you’ll get an in-depth look at how to design and build a single-page, rich Internet Application (RIA).
