Why use omnifaces while I am using primefaces?

Question

I need to know what the benefits of using OmniFaces would be versus PrimeFaces which I'm using at the moment. What features does OmniFaces offer that PrimeFaces doesn't?

Answer 1

They are different things and you can perfectly combine them.

• Omnifaces is a utility for JSF which enhances JSF itself. It's not intended to just provide built-in view components (even it has some of them), but to improve JSF standard API providing utilities as their own converters, filters, functions and validators. According to its showcase:

OmniFaces is a utility library for JSF 2 that focusses on utilities that ease everyday tasks with the standard JSF API. OmniFaces is a response to frequently recurring problems encountered during ages of professional JSF development of the JDevelopment team and from questions being asked on Stack Overflow.

• Primefaces is a library of view components for JSF. They are focused in helping you with already built in components which combine jQuery, Javascript and CSS styling. You can have a look to all of them in their showcase.

From the OmniFaces showcase: "The UI which you see on this showcase is done by PrimeFaces 6.1" – Tallyho

@JasperdeVries: Please note that OmniFaces is a JSF utility library, not a JSF UI/component library. The UI which you see on this showcase is done by PrimeFaces 6.1, with a little bit of custom CSS. I think the whole paragraph backs this answer up. – Engelhart
