The Zen of Dojo

Duration: 3 Days

Audience

Prerequisites

This course is designed for experienced Web application developers and professionals:

Architects
Designers
Consultants
Developers
Web 2.0 Developers

Attendees must be conversant in Web applications, HTML and JavaScript. Familiarity with AJAX would be helpful but not necessary.

For JavaScript and AJAX, we recommend the following two courses respectively.

Description

Dojo has recently caught the attention as a popular AJAX toolkit. But it is much more than that. Quite simply put, it is an Open Source JavaScript UI toolkit. It makes writing JavaScript easier, building dynamic UIs very simple and interacting with server-side components a breeze. The foundation of Dojo is "Dojo Base", a single tiny library which contains Ajax, event handling, effects, quick CSS queries, language utilities, and a lot more.

On top of this Base, the rest of Dojo Core adds high-quality facilities for Drag and Drop, extended forms of Ajax and I/O, JSON-RPC, internationalization, back-button handling etc.

Layered on Dojo Core is the widget system, Dijit, for building UI components easily. If you can write HTML and CSS, Dijit allows you to quickly build reusable client-side components (by using extended attributes on HTML). By upgrading standard HTML instead of inventing a new markup language, Dijit makes building powerful Web 2.0 UIs very easy to learn.

This three day course does an in-depth look at the various parts of Dojo both from a client side as well as server side perspective. This will give you the tools to become facile with Dojo and to even extend it suit your requirements.

We use the latest stable version of Dojo in this class.
