Being able to extend and customize the editorial experience for users has been a part of any WordPress developer’s toolbox since hooks were introduced in WordPress 1.2. We have come a long way since then and now with the Gutenberg Project, we have a new tool available to us – SlotFill.
The SlotFIll system can be used to extend blocks and the UI for the Block Editor and Site Editor screens making it a critically important tool for any WordPress developer. This talk will take a deep dive into how this system works, show how and where you can currently extend WordPress, and finally how to create your own custom SlotFills!
