A lightweight & efficient EventManager for JS in WP.

See ticket #21170 for more information. We also did a general overview of the project at WordSesh that you can find here.

WP-JS-Hooks does not require any third-party applications or software. The library is completely self-maintained. However, the repository itself uses Grunt to perform tasks such as JSHint, Uglify, and QUnit. For more information on how to install Grunt, please visit http://gruntjs.com

API functions can be called via the global wp.hooks like this wp.hooks.addAction(), etc.

• addAction( 'namespace.identifier', callback, priority )
• addFilter( 'namespace.identifier', callback, priority )
• removeAction( 'namespace.identifier' )
• removeFilter( 'namespace.identifier' )
• doAction( 'namespace.identifier', arg1, arg2, moreArgs, finalArg )
• applyFilters( 'namespace.identifier', content )

• Fast and lightweight, only 1.3kb
• Priorities system ensures hooks with lower integer priority are fired first.
• Uses native object hash lookup for finding hook callbacks.
• Utilizes insertion sort for keeping priorities correct. Best Case: O(n), worst case: O(n^2)

• 4/24/13
  • Reduced repository size by removing an old node_modules folder from repo history.
