Is there a resource showing all the J3 classes mapped to the J4 equivalents?

Question

I know we are using

Factory instead of JFactory

I would like to know if there is an easy way to know the mapping.

I'd also like to understand if any have been deprecated or replaced. Is there a good resource for this?

Answer 1

You can find the equivalent of Joomla! classes here:

• https://github.com/joomla/joomla-cms/blob/4.0-dev/libraries/classmap.php

Your IDE will show when a method is deprecated in your code if you set as dependency the Joomla 4.0 git directory cloned locally.
