Gatsby & WordPress - 2.6. - ACF Gutenberg Block Development
Hey! This post's a little over two years old now, so some of what's here might be out of date. Still worth a read, but if anything really matters to you, it's worth double-checking against a newer source too.
In this advanced concept video, I cover how you can build your own custom Gutenberg blocks using the ACF Pro plugin and then show the block attributes in your schema.
In a later video, I'll be covering how we can improve the editing experience with previews of what the blocks will render as, within our WordPress editor.
ACF's own native block registration (via acf_register_block_type) and the WPGraphQL ACF addon have both changed considerably since 2019 — check current ACF and WPGraphQL docs before following this approach today.
