A Deep Dive into Creating Custom Gutenberg Blocks in WordPress (Updated for 2023)


In the ever-evolving landscape of WordPress, the Gutenberg editor stands as a testament to the platform’s commitment to user-friendly and dynamic content creation. One of the most exciting features of Gutenberg is the ability to design and implement custom blocks. In this comprehensive tutorial, we’ll explore the intricate process of creating your own Gutenberg custom blocks, utilizing the latest tools and techniques available in 2023.

Understanding the Gutenberg Block Structure:

Before we embark on our journey of creating custom blocks, it’s essential to understand the structure of a Gutenberg block. At its core, a block is a modular unit that represents a specific piece of content or functionality. Blocks can range from simple elements like paragraphs and images to more complex components like galleries and custom forms.

Step 1: Setting Up Your Development Environment

A solid development environment is the foundation of efficient block creation. Utilize tools like MAMP, WampServer, or Local by Flywheel to set up a local WordPress installation for testing. Pair it with a robust code editor such as Visual Studio Code or Atom for seamless development.

Step 2: Choosing the Right Approach

In 2023, developers have various approaches to create custom Gutenberg blocks. One popular method is utilizing the @wordpress/create-block package, a Node.js tool that streamlines the block creation process. Begin by installing this package globally using the following command:

npm install -g @wordpress/create-block

Step 3: Scaffolding Your Custom Block with @wordpress/create-block

Once the package is installed, navigate to your desired plugins directory and run the following command to create a new custom block:

npx @wordpress/create-block custom-gutenberg-block

This command will create a new directory named ‘custom-gutenberg-block’ containing all the necessary files to get you started.

Step 4: Understanding the File Structure

Navigate into the newly created block directory. You’ll notice a structured set of files and folders. The ‘src’ folder is particularly important as it holds the core files for your block:

  • edit.js: Defines the block’s behavior within the editor.
  • index.js: Enqueues scripts and styles for your block.
  • style.scss: Contains the styling for your block.

Step 5: Enqueueing JavaScript and CSS Files

Open the ‘index.js’ file within the ‘src’ folder. This is where you’ll enqueue your block’s JavaScript and CSS files. These files determine the behavior and appearance of your block.

// index.js

import './style.scss';
import './editor.scss';

// Your block code goes here

Step 6: Defining Your Block

The ‘edit.js’ file, also located in the ‘src’ folder, is where you define the attributes and behavior of your custom block. This is where your block’s unique features come to life.

// edit.js

const MyCustomBlock = () => {
  return <p>Your custom block content goes here!</p>;

export default MyCustomBlock;

Step 7: Styling Your Block

Crafting a visually appealing block is crucial for user engagement. Create a ‘style.scss’ file within the ‘src’ folder to define the custom styles for your block.

// style.scss

// Your custom styles go here

Step 8: Testing Your Custom Block

Activate your custom block plugin in the WordPress dashboard and create a new post or page. Your block should now be accessible in the Gutenberg editor. Test its functionality, appearance, and responsiveness to ensure a seamless user experience.

Step 9: Advanced Customization with Additional Features

As you become more familiar with creating Gutenberg blocks, consider exploring advanced features such as:

  • Attributes and Controls: Define dynamic attributes for your block and create controls for users to interact with these attributes.
  • Block Toolbar: Implement a custom toolbar for your block, offering additional options and settings.
  • Server-Side Rendering: For more complex blocks, explore server-side rendering to enhance performance and efficiency.


Creating custom Gutenberg blocks in WordPress is a dynamic and empowering process. In this tutorial, we’ve covered the essential steps, from setting up your development environment to utilizing modern tools like @wordpress/create-block for efficient block creation. As you embark on your journey of customization, remember to experiment, iterate, and explore the endless possibilities that Gutenberg offers for crafting unique and engaging content in 2023. Happy coding!
