HeadJS is a tiny JavaScript library that loads scripts and stylesheets asynchronously in parallel while executing them in order, and provides browser/feature detection with CSS class generation. It also offers pseudo media-queries for responsive design in legacy browsers like IE6.
Use cases
- load javascript and css files asynchronously in parallel but execute in order
- detect browser versions and html5/css3 feature support
- apply responsive design css classes for different screen resolutions
- manage script dependencies and run callbacks when scripts are loaded
- support html5 elements in old browsers like ie6
- detect landscape vs portrait orientation or mobile vs desktop device
When to choose
- maintaining a legacy site that must support old browsers like IE6-IE9
- you need a tiny all-in-one script loader and feature detection shim for an old codebase
When to avoid
- starting a new modern project - use native module loading, modern CSS media queries, and feature detection libraries instead
- you need actively maintained software with security updates
