Warning: JSDuck is no more maintained!

• If you're looking to adopt a documentation tool, try something else.
• If you're using JSDuck, consider moving over to something else.
• Even Sencha itself doesn't use it any more, they use some internal tool, that's not available publicly.
• If you'd like to take over the maintenance of JSDuck, contact me by creating an issue.

API documentation generator for Sencha JavaScript frameworks.

JSDuck aims to be a better documentation generator for Ext JS than the old ext-doc was. It is used by Sencha to document Ext JS 4, Sencha Touch and several other products.

The highlights of JSDuck are Markdown support and keeping you DRY by inferring a lot of information from code. Read the documentation for full overview.

New to JSDuck? Watch introductory talk by Nick Poulden:

Getting it

Standard rubygems install should do:

$ [sudo] gem install jsduck

Or download the Windows binary. When you run into problems, see the installation guide.

Usage

For the simplest test-run just use the --builtin-classes option to write documentation for JavaScript builtin classes like Array, String and Object into docs directory:

$ jsduck --builtin-classes --output docs

To generate docs for Ext JS 4 add path to the corresponding src/ dir:

$ jsduck ext-4.2.1/src --output docs

And to create docs for your own Ext JS project, list the directory with your files in addition to the Ext JS source files (this way the docs of your classes will list all the properties and methods they inherit from Ext JS classes):

$ jsduck ext-4.2.1/src my-project/js --output docs

Unfortunately the above will throw lots of warnings at you, as building the full Ext JS docs requires lots of additional settings. For start you might want to simply ignore all these warnings originating from Ext JS source:

$ jsduck ext-4.2.1/src my-project/js --output docs \
         --warnings=-all:ext-4.2.1/src

But see the Usage guide for more information on building Ext JS 4 docs.

Documenting your code

Read the documentation and take a look at example.js.
