Day 30: Best Practices for Gutenberg Development

Introduction

Welcome to Day 30 of the Gutenberg development series! Over the past 29 days, we’ve explored a wide range of topics, from creating simple blocks to building dynamic templates and optimizing performance. Today, we’ll summarize the best practices you should follow as a Gutenberg developer to ensure that your blocks are efficient, user-friendly, and scalable.

In this article, you’ll learn about:

• Best coding practices for Gutenberg block development.
• Ensuring maintainable and scalable code.
• Tips for delivering a great user experience in the Block Editor.

1. Write Clean, Modular Code

Modular code is easier to maintain, test, and reuse across different projects. Focus on breaking down complex components into smaller, reusable functions or components.

Tips for Writing Modular Code:

• Use Custom Hooks: For repetitive logic in your blocks, create custom React hooks to keep your components clean.
• Separate Styles: Keep your CSS separate from the block’s JavaScript to avoid clutter and make style adjustments easier.
• Use Helper Functions: For complex calculations or repeated logic, use helper functions to keep your block logic simple.

// Example of a custom hook
const useCurrentUser = () => {
    const user = useSelect((select) => select('core').getCurrentUser());
    return user;
};

2. Follow WordPress Coding Standards

Adhering to WordPress coding standards ensures that your code is consistent with the rest of the ecosystem and makes collaboration easier.

Key Standards to Follow:

• JavaScript: Follow the JavaScript Coding Standards.
• PHP: For blocks with server-side logic, follow the PHP Coding Standards.
• CSS: Use the CSS Coding Standards to ensure consistency in your styles.

3. Prioritize Accessibility

Accessibility is crucial for ensuring that all users, including those with disabilities, can interact with your blocks. Make sure your blocks comply with accessibility standards.

Accessibility Best Practices:

• Use ARIA Attributes: Add ARIA roles and attributes to ensure screen reader compatibility.
• Focus Management: Ensure that interactive elements like buttons and forms are keyboard accessible.
• Readable Colors: Use sufficient color contrast in your block designs for readability.

4. Optimize for Performance

As covered in Day 29, performance is a key aspect of a good user experience. Focus on minimizing your block’s impact on the Block Editor’s performance.

Performance Tips:

• Lazy Load Components: Load heavy components only when needed to reduce the initial load time.
• Minify Assets: Use tools like Terser and CSSNano to minify your JavaScript and CSS.
• Use Server-Side Rendering: For blocks that involve complex logic or data fetching, consider rendering them on the server.

5. Leverage the Block Editor API

WordPress provides a robust API for creating and managing blocks. Use the available APIs to streamline your block creation process.

Recommended APIs:

• useSelect and useDispatch: For interacting with the WordPress data store.
• InspectorControls: For adding custom settings to the block sidebar.
• Block Variations API: For offering different styles or configurations of the same block.

import { useSelect, useDispatch } from '@wordpress/data';

6. Create a Great User Experience

The goal of Gutenberg is to provide a visual and intuitive way of building content. Keep the end-user experience in mind when developing blocks.

User Experience Tips:

• Provide Clear Labels: Use descriptive labels and placeholders to guide users.
• Add Helpful Previews: Include block previews to help users understand what each block does before adding it to the content.
• Use Placeholders for Guidance: For complex blocks, use placeholder content to show users where they can start editing.

7. Maintain Up-to-Date Documentation

As your blocks evolve, ensure that your documentation stays current. Good documentation helps users understand how to use your blocks and aids developers in maintaining them.

Documentation Best Practices:

• Include Code Examples: Show how to use each block with code snippets.
• Provide Usage Scenarios: Describe common use cases for each block to help users get started.
• Update Regularly: Keep your documentation in sync with any updates to your blocks.

8. Test Thoroughly Across Different Environments

Ensure that your blocks work seamlessly across different WordPress versions, themes, and plugins.

Testing Recommendations:

• Cross-Browser Testing: Verify that your blocks work well in all major browsers.
• Compatibility with Popular Themes: Test with popular themes like Twenty Twenty-One to ensure consistent styling.
• Use Debugging Tools: Tools like React DevTools and WP-CLI can help identify issues during development.
