Create-acf-block-json NPM

Create ACF Block JSON

Quickly create a new WordPress Block that uses Advanced Custom Fields (ACF) and utilises block.json and block-specific CSS and PHP files.

If you use ACF and make Gutenberg blocks, this simple utility should save you time scaffolding custom blocks.

Quick Start

Install globally via npm:

npm install --global create-acf-block-json

then navigate to where you want your block to be (i.e. /theme/blocks/), and run:

$ create-acf-block-json

What does Create ACF Block JSON do

Create ACF Block JSON is an npm package command line program that will create a new folder in your current directory containing scaffolding for a new WordPress block using Advanced Custom Fields.

It will generate:

Folder - containg folder for your block.
block.json - prefilled with common block information and default values.
PHP file - setup with basic information, classes and innerblocks.
SCSS files - for the frontend and editor. SCSS is useful if you use a compiler to output CSS files.
CSS file - for the frontend and editor. To write straight CSS or be overwritten by your processed SCSS.

The script handles generating a unique class (.wp-block-namespace-name) for your block which is then referenced in each file.

This script doesn't handle registration of the block - we recommend directory scanning methods to auto load blocks without registering each one. This method is outlined by Bill Erickson, but there are other examples online. But if you need an easier solution to register an ACF block, follow this guide. FYI, many guides are out of date, make sure you use guides released after 28th September 2022 (when ACF 6.0 was released) which will properly use block.json.

Customisation Options

When you run create-acf-block-json you are asked a few questions before your block is created:

Namespace: Specify a namespace for the block (defaults to acf)
Name: Give your block a name, i.e. "My Cool Block" (required)
Description: Describe the functionality of your block so editors and users can find it easily (optional)
Icon: The icon for your block - use any Dashicons name (defaults to icon star-filled). Note, when copying the name of the Dashicon you must remove the prefix dashicons-, for example: dashicons-smiley should be written as smiley.

The script will then generate all required files. From there, you can edit, delete, remove the files as you wish.

Install Create ACF Block

Using terminal or another CLI, download from npm and install as a global package - npm install -g create-acf-block-json
Using terminal or another CLI, navigate to your WordPress theme folder where you want all of your blocks (we use /wp-content/themes/my-theme/blocks/)
Run create-acf-block-json and follow prompts.
