How does this skill help with SEO?

It provides patterns for pre-rendering state on the server using PHP, ensuring that interactive content is indexable by search engines before JavaScript even loads.

What is the WordPress Interactivity API?

It is a standard framework for adding frontend interactivity to WordPress blocks using a declarative, directive-based approach that ensures compatibility and performance.

Does this skill support the latest WordPress updates?

Yes, it specifically includes support for WordPress 6.9+ changes, such as the deprecation of data-wp-ignore and the use of unique directive IDs with triple-dash separators.

Why are my WordPress directives not firing?

Common causes include missing the data-wp-interactive root, incorrect store namespace, or viewScriptModule entry points not being registered in block.json.

Content Management

Develops and debugs interactive WordPress blocks using the Interactivity API and standardized data-wp directives.

About

This skill provides deep technical guidance for the WordPress Interactivity API, enabling developers to build high-performance, interactive frontend experiences within the WordPress ecosystem. It covers the full implementation lifecycle, from server-side rendering (SSR) and state initialization in PHP to client-side hydration and store management. By following modern WordPress core standards, it helps optimize performance, resolve hydration mismatches, and ensure that interactive components are both SEO-friendly and accessible.

Key Features

Support for WordPress 6.9+ features including unique directive IDs and new TS types
Server-side rendering (SSR) setup for improved SEO and perceived load time
Advanced debugging for hydration errors and inert frontend components
34 GitHub stars
Automated implementation of data-wp-* directives and store logic
Guidance on block viewScriptModule integration and WP-CLI workflows

Use Cases

Fixing hydration mismatches where frontend behavior doesn't match server markup
Building dynamic, interactive blocks like instant search, carts, or live filters
Migrating legacy jQuery or vanilla JS interactions to the official Interactivity API
