Venkman Introduction
An overview and some practical examples of using the JavaScript Debugger in web development.

Venkman is the code name for Mozilla's JavaScript Debugger. Venkman aims to provide a powerful JavaScript debugging environment for Mozilla based browsers namely Firefox 2.x, Netscape 7.x/9.x and SeaMonkey 1.x/2.x. It does not include Gecko-based browsers such as K-Meleon 1.x, Galeon 2.x and Netscape 8.x. The debugger is available as an add-on package in XPI format. Venkman JavaScript Debugger has been provided as part of the Mozilla install distribution since October 2001.

Brief History

In 1998, John Bandhauer was in charge of creating the Netscape 4x JavaScript debugger. In order to keep things modular, he began by creating a mid-level JavaScript debugging API known as js/jsd. This API augments the existing JavaScript API, providing clients with a useful set of debugger functionality implemented in C. John then went on to reflect that API into Java, and create his cross platform front end, eventually producing Netscape JavaScript Debugger 1.0 and 1.1.

In April of 2001, Robert Ginda began work on a JavaScript debugger for Mozilla, called Venkman. Venkman builds on the js/jsd portion of John's 1998 work, {{template.Source("js/jsd/idl/jsdIDebuggerService.idl", "exposing it")}} as an XPCOM component. This allows the {{template.Source("extensions/venkman/resources/content/", "user interface")}} be written in JavaScript and XUL, which allows Venkman to be fully cross platform.

Getting Venkman

Firefox, Thunderbird and Netscape Navigator 9
The latest version of Javascript Debugger is available from Firefox Add-ons.
Mozilla Suite and SeaMonkey
These releases come with Venkman pre-installed. On Windows, it is an install option; choose Advanced install. Also available from Firefox Add-ons as an extension.
Nvu and KompoZer
Javascript Debugger extension version 0.9.84 is available from Nvu's downloads page. We encourage you to use the latest available version 0.9.87 (or higher) with Firefox instead.
