Wp Block Development

This is a comprehensive workflow for building and maintaining WordPress Gutenberg blocks, covering everything from scaffolding with @wordpress/create-block to handling the tricky parts like attribute serialization, deprecations, and dynamic rendering. It enforces apiVersion 3 for WordPress 6.9+ compatibility and walks you through block.json metadata, registration patterns, and the differences between static versus dynamic blocks. The procedure is opinionated about using filesystem detection scripts and metadata-based PHP registration. Most valuable when you're dealing with "invalid block" errors after markup changes or need to add viewScriptModule support without breaking existing blocks. It assumes you have bash, node, and optionally WP-CLI available in your environment.
