To create a custom Gutenberg block with React, you will need to follow a few steps:
- Set up a WordPress development environment: Install WordPress on your local machine using a development environment like MAMP or XAMPP. Setup a theme or plugin development environment by creating necessary files and folders.
- Initialize a new Gutenberg block: Inside your theme or plugin directory, create a new folder for your block. Open a terminal and navigate to that folder. Run the command npx create-guten-block my-custom-block to generate the basic structure for your custom block.
- Modify the block files: Navigate to the newly created block folder. Locate and open the src/block/block.js file. Here you will define the block by creating a new React component. Customize it according to your needs, such as setting up block attributes, defining block settings, and configuring block behavior.
- Add styling: Open the src/block/style.scss file to add CSS styles specific to your Gutenberg block. Customize the styling as per your requirements.
- Build the block: To compile your block code, back in the terminal, navigate to the block folder and run npm run build or yarn build. This will create a build folder containing the compiled JavaScript and CSS code.
- Enqueue block assets: Within your theme or plugin, enqueue your block assets using the enqueue_block_assets and enqueue_block_editor_assets hooks. This ensures that your block's script and stylesheets are loaded on the Gutenberg editor and site front-end.
- Register your block: Use the registerBlockType function to register your custom block with WordPress. This function takes arguments such as the block name, block settings, and block editor.
- Test and refine: Save your changes and reload your WordPress admin area. You should be able to see and add your custom block in the Gutenberg editor. Test the block's functionality and appearance, refine the code as necessary, and repeat the build process if needed.
By following these steps, you can create a custom Gutenberg block using React, allowing you to extend the functionality of the WordPress editor with your own custom elements and features.

Once the Gutenberg plugin is activated, you can start using the Gutenberg editor for creating and editing your WordPress posts and pages.
How to add block variation options to a custom Gutenberg block?
To add block variation options to a custom Gutenberg block, you need to implement the registerBlockVariation
function in your block's JavaScript file. Here are the steps to follow:
- Create or locate the JavaScript file of your custom Gutenberg block. This file contains the block's definition and behavior.
- In the JavaScript file, import the registerBlockVariation function from the @wordpress/blocks package. It can be imported using the following statement:
1
|
import { registerBlockVariation } from '@wordpress/blocks';
|
- Use the registerBlockVariation function to add each variation to the block's options. This function requires two parameters: the block name and an object containing the variation settings. For example:
1 2 3 4 5 6 7 |
registerBlockVariation('your-block-name', { name: 'variation-1', title: 'Variation 1', description: 'Description of Variation 1', icon: 'heart', isDefault: true, // Set it to true if this variation should be the default one }); |
The registerBlockVariation
function should be called for each variation you want to add to the block. Repeat the call, changing the name
, title
, description
, and icon
properties accordingly.
- Finally, make sure to build your JavaScript file and enqueue it properly in WordPress to see the block variations in the Gutenberg editor.
By following these steps, you should be able to add block variation options to your custom Gutenberg block.
How to add styles to a custom Gutenberg block using React?
To add styles to a custom Gutenberg block using React, you can follow these steps:
- Open the file where your custom block is defined. This is typically the index.js file in your block's folder.
- Import the InspectorControls and InnerBlocks components from the Gutenberg package:
1
|
import { InspectorControls, InnerBlocks } from '@wordpress/block-editor';
|
- Define a new function component for your custom block, and include the InspectorControls component at the top:
1 2 3 4 5 6 7 8 9 10 11 12 |
const MyCustomBlock = (props) => { return ( <> <InspectorControls> {/* Add custom controls for your block */} </InspectorControls> <div className="my-custom-block"> {/* Contents of your block */} </div> </> ); }; |
- Use the className attribute to assign a unique class name to your block's container:
1 2 3 |
<div className="my-custom-block"> {/* Contents of your block */} </div> |
- Open the block's corresponding style.scss file to define the styles for your block. If the file does not exist, create it in the same folder as your index.js file.
- In style.scss, add the custom class name of your block, prefixed with .wp-block- to target the block specifically:
1 2 3 |
.wp-block-my-custom-block { /* Add your styles here */ } |
- Write your desired CSS styles inside the block's class selector.
- Save the changes and preview your block. The styles defined in style.scss should now be applied. Remember to compile your Sass stylesheets if you're using a build system like webpack or gulp.
By following these steps, you can add custom styles to your Gutenberg block using React.
What are React components and how to create them?
React components are independent and reusable building blocks of a React application. They allow you to divide your user interface into modular pieces, making it easier to manage and maintain your codebase. Each component can have its own properties and state, and can be composed with other components to create complex user interfaces.
To create a React component, you can use either functional components or class components.
- Functional Components:
Functional components are simple JavaScript functions that return JSX (a syntax extension for JavaScript that allows writing HTML-like structures). Here's an example of a functional component:
import React from 'react';
function MyComponent(props) {
return Hello, {props.name}!; } export default MyComponent;
- Class Components:
Class components are JavaScript classes that extend the React.Component class. They have additional features such as access to lifecycle methods and ability to manage state. Here's an example of a class component:
import React from 'react';
class MyComponent extends React.Component {
render() {
return Hello, {this.props.name}!; } } export default MyComponent;
Both functional and class components can then be imported and used in other parts of your application like any other HTML element. For example:
1 2 3 4 5 6 7 8 9 10 11 12 13 |
import React from 'react'; import MyComponent from './MyComponent'; function App() { return ( <div> <h1>Welcome to My App</h1> <MyComponent name="John" /> </div> ); } export default App; |
In this example, we create an App
component that renders a MyComponent
component with a name
prop. The MyComponent
component will display "Hello, John!" as the output.
What is the role of the InnerBlocks component in Gutenberg block development?
The InnerBlocks component is a fundamental part of Gutenberg block development. It allows developers to create dynamic blocks that can contain other blocks within them. The InnerBlocks component acts as a container for multiple blocks, allowing for the creation of complex block structures.
Using the InnerBlocks component, developers can define the allowed blocks that can be added within a specific block. The InnerBlocks component also provides options for adding and removing blocks within the container block, making it possible for users to customize the content of the block.
In addition, the InnerBlocks component allows for nested blocks, meaning that one block can contain another block, which can contain another block, and so on. This nesting capability enables developers to create intricate and flexible block layouts.
The InnerBlocks component also provides mechanisms for saving and loading the block's content, allowing for seamless editing and persistence of the block structures.
Overall, the InnerBlocks component is essential for creating dynamic and customizable blocks in Gutenberg, enabling developers to build powerful and rich block-based layouts.
