WPLib is a plugin designed to be used as a Must-Use plugin or to be embedded in a theme to enable the development of complex yet robust and performant WordPress applications and websites.
WPLib is a foundation library upon which robust applications can be developed. WPLib is not intended for use by end-users but instead by professional PHP developers who are tasked with building specific applications or sites on the WordPress platform by their company or their clients.
Think of developing with WPLib to be somewhat like:
“The joy of programming in Lavarel while respecting everything about WordPress that makes it an ideal platform for developing content management solutions.”
The WPLib source code is hosted and development occurs on GitHub and the documentation site will soon be located at wplib.org.
