Key Features of the Interactivity API
The WordPress Interactivity API introduces a standardized way to create dynamic, reactive blocks. It simplifies development with declarative coding, modularity, and server-side rendering for enhanced performance and SEO.
Directives
Directives like data-wp-bind, data-wp-on, and data-wp-context make WordPress interactivity declarative and easy to implement. Just a few attributes can transform your static blocks into dynamic, interactive features. These directives eliminate the need for heavy JavaScript, offering a clean and consistent coding experience.
State and Context
State offers a global scope for variables, while context keeps things local to a specific block. This distinction enables modularity and reusability, making your blocks more efficient and scalable. Together, they allow seamless communication between blocks while maintaining a lightweight architecture.
Server-Side Rendering (SSR)
The API delivers fully rendered HTML to browsers, ensuring faster page loads and boosting SEO performance. It’s lightweight yet robust, thanks to its integration with Preact. By combining SSR with reactivity, it ensures both users and search engines experience optimized, interactive websites.

Why Use the Interactivity API?
The WordPress Interactivity API is a game-changer for developers, offering a streamlined approach to building dynamic, responsive websites. Here’s why it stands out:
Comparison with Traditional Methods
Gone are the days of tedious manual DOM manipulation and relying on heavy JavaScript frameworks like React or Vue. The Interactivity API simplifies everything, providing a declarative way to build interactivity directly within WordPress.
Time-Saving Benefits
By enabling reusable, modular blocks, the API significantly reduces development time. With its intuitive directives and server-side rendering, developers can achieve more in less time, focusing on creativity rather than repetitive coding.
Scalable and Modular
Whether you’re building a small blog or a complex enterprise application, the API’s modular approach ensures scalability. Its ability to handle both global states and localized contexts makes it ideal for creating adaptable and maintainable solutions.

Getting Started with the WordPress Interactivity API
The Interactivity API makes it easy to transform your blocks into interactive features with minimal effort. Here’s a quick guide to get you started:
Step 1: Enabling the API in block.json
To activate the Interactivity API for your block, add the following code to the block.json file:
"supports": {
"interactivity": true
}This setting enables interactivity for your custom block, laying the foundation for dynamic functionality.

Step 2: Setting Up Directives in Render.php
Use directives like data-wp-bind or data-wp-on in your block’s PHP render file to define interactivity directly within your HTML. For example, to toggle the visibility of an element:
<div data-wp-bind--hidden="isHidden">
This content is dynamically visible!
</div>These directives eliminate the need for complex JavaScript logic, making interactivity seamless and declarative.
Step 3: Writing the View.js File
The view.js file is where you define your block’s behavior. Use the store function to manage state and actions efficiently. For instance, here’s how you can toggle a state:
import { store } from '@wordpress/interactivity';
const toggleVisibility = store({
isHidden: false,
toggle() {
this.isHidden = !this.isHidden;
}
});
export default toggleVisibility;This setup allows you to manage block-specific interactions while keeping the code modular and reusable.
By following these steps, you’ll be ready to build highly interactive WordPress blocks that combine simplicity and functionality. The Interactivity API streamlines the process, letting you focus on crafting exceptional user experiences.

Example Implementations of the WordPress Interactivity API
Let’s dive into some real-world applications of the WordPress Interactivity API. Below are two example blocks that showcase its capabilities and how it simplifies complex interactions with minimal code.
6.1. Live Search Block
The Live Search Block dynamically updates search results as users type, providing a seamless real-time experience.
Code Implementation:
Enable Interactivity in block.json:
{
"supports": {
"interactivity": true
}
}Render the Live Search in PHP (render.php):
<div data-wp-context>
<input
type="text"
placeholder="Search..."
data-wp-bind="query"
data-wp-on--input="searchPosts"
/>
<ul>
<li data-wp-for="result in results" data-wp-bind--text="result"></li>
</ul>
</div>Define the Logic in View.js:
import { store } from '@wordpress/interactivity';
const searchStore = store({
query: '',
results: [],
searchPosts() {
if (this.query.length < 2) {
this.results = [];
return;
}
fetch(`/wp-json/wp/v2/posts?search=${this.query}`)
.then(response => response.json())
.then(data => {
this.results = data.map(post => post.title.rendered);
});
}
});
export default searchStore;Accordion Block
The Accordion Block enables toggling visibility for collapsible content, ideal for FAQs and content-heavy pages.
Code Implementation:
Enable Interactivity in block.json:
{
"supports": {
"interactivity": true
}
}Render the Accordion Block in PHP (render.php):
<div data-wp-context>
<button data-wp-on--click="toggle">Toggle Section</button>
<div data-wp-bind--hidden="!isOpen">
<p>This is the accordion content, visible when toggled open.</p>
</div>
</div>Define the Logic in View.js:
import { store } from '@wordpress/interactivity';
const accordionStore = store({
isOpen: false,
toggle() {
this.isOpen = !this.isOpen;
}
});
export default accordionStore;Key Differences
- Live Search Block: Focuses on real-time updates based on user input (data-wp-bind, data-wp-on–input) and interacts with the REST API for dynamic data updates.
- Accordion Block: Focuses on toggling visibility of content using a straightforward toggle() function and directives like data-wp-bind–hidden.

Pro Tips for Using the Interactivity API
Take your WordPress interactivity skills to the next level with these expert tips:
1. Getters in State
Getters are a powerful tool for managing complex conditions in your application. Instead of recalculating values or writing repetitive logic, define a getter in your store for seamless state management.
Example:
const store = {
items: [10, 20, 30],
get total() {
return this.items.reduce((sum, item) => sum + item, 0);
}
};
console.log(store.total); // Outputs: 602. Cross-Block Communication
Enhance user experience by sharing states across multiple blocks. For instance, use shared states for updating a cart icon when users add items to their cart or displaying notifications globally.
How to Achieve This: Use a shared store that multiple blocks can access.
import { store } from '@wordpress/interactivity';
const sharedStore = store({
cartCount: 0,
incrementCart() {
this.cartCount++;
}
});
export default sharedStore;3. Loop Directives (data-wp-for)
Use the wp-each directive to build dynamic lists effortlessly. This is especially useful for displaying posts, comments, or product grids.
Example:
<ul>
<li data-wp-for="item in items" data-wp-bind--text="item"></li>
</ul>JavaScript:
import { store } from '@wordpress/interactivity';
const listStore = store({
items: ['Item 1', 'Item 2', 'Item 3']
});
export default listStore;Find: Best Interactive Websites Inspiration
