In the WordPress block editor (a.k.a. Gutenberg) the “Featured Image” is rendered at the WordPress ‘large’ image size by default. By adding a WordPress JavaScript filter to the ‘editor.PostFeaturedImage.imageSize’ hook, we can change this default rendering.

WordPress View Block Attributes
When developing a WordPress plugin that creates a Gutenberg block, it is invaluable to be able to view the attributes on the block. Here are some tricks I use to view this information.
WordPress Gutenberg Trigger Autosave
Recently, I was documenting the steps to reproduce a certain bug and the bug required the presence of an autosave (along with the “There is an autosave of this post that is more recent than the version below.” message).

WordPress Gutenberg Functional Component useState
When creating a block for the WordPress block editor (a.k.a. Gutenberg), I find that most of the documentation is for class components. However, with React hooks we can use functional components. When you need to import ‘useState’ from React, you can do it as follows in a WordPress block.
