Why Build Custom Blocks?
Gutenberg is the future of WordPress content editing. While there are plenty of block libraries available, custom blocks give you precise control over output, design, and functionality — without the bloat of a block plugin.
Setting Up Your Development Environment
The easiest way to scaffold a new block is with the official @wordpress/create-block package. It sets up the build tooling, file structure, and WordPress integration automatically.
Anatomy of a Block
Every Gutenberg block consists of three parts: the registration (block.json), the editor view (edit.js), and the frontend output (save.js or PHP render callback). Understanding this separation is key to building reliable blocks.
Best Practices
Use block.json for metadata, leverage InnerBlocks for composable content, implement proper block supports for color and spacing, and always provide a PHP render callback for dynamic content.
