The new WordPress editing experience is a major disruption (but ultimately a positive one) for any developer whose plugins or themes intersect with the editor UI. While existing shortcodes and metaboxes may still work (if you’re lucky), the sooner you can transition to native Gutenberg UI components the better.
David Carr will use the example of RSVPMaker, a plugin he has supported since 2006, to share the learning process of turning shortcodes into Gutenberg blocks and gradually learning how to tap into the strengths of the Gutenberg UI framework. As a writer and editor who codes on the side, he had made some use of JQuery but had to climb a steep learning curve to come up to speed on “modern JavaScript” with node.js and React. His goal with this talk is to help you climb that learning curve faster.
Recently, David has released a couple of Gutenberg-specific plugins, Floating Callout and My Marginalia.
