On the Delicious Brains site, there's a tutorial posted asking WordPress plugin developers if their code is ready to work with Gutenberg, the next major release of the editor used in the popular blogging tool and content management system.

WordPress 5.0 is right around the corner with the flagship feature, the new Gutenberg editor, set to change the WordPress landscape dramatically. Gutenberg not only impacts how you write content in WordPress, but how developers build plugins for WordPress.

[...] In this post I’ll walk you through the process I took for making Intagrate, my Instagram WordPress plugin, Gutenberg-compatible, which will hopefully get you started on making your own plugins Gutenberg-ready.

The post starts with some general things to consider about Gutenberg's functionality as compared to the classic editor and some key places to check in your own plugins. They then provide a guide to testing your plugin by installing the standalone editor package. It then walks through the three main places to check functionality:

• custom post types
• custom meta boxes
• TinyMCE

The post ends with some suggestions of possible enhancements such as making use of shortcodes and converting custom meta boxes.
