PrimeUI doesn't merely wrap around jQuery UI, but it enhances it by allowing developers to work with REST and JSON for passing data to the UI widgets.
This makes PrimeUI ready for usage with any server-side programming language or technology, since most of them can manage REST and JSON data with ease.
PrimeUI can be the base for any future Web project, helping developer easily prototype their application's interfaces.
All original jQuery UI are supported, and a few new ones as well, along with ThemeRoller skins.
PrimeUI development has spun out of the PrimeFaces JSF components library.
