Install React js in wordpress.

Installing React in WordPress can be done by following these steps:

1. Install and activate the “Advanced Custom Fields” plugin. This plugin allows you to add custom fields to your WordPress posts and pages.
2. Install and activate the “Create React App” plugin. This plugin allows you to easily create a React app within your WordPress site.
3. Create a new React app by going to “Tools” > “Create React App” in the WordPress admin menu and following the prompts.
4. Once the React app is created, you can add it to your posts and pages by creating a custom field for it using the Advanced Custom Fields plugin.
5. Add the React app to your WordPress theme by enqueuing the React app’s JavaScript and CSS files in your theme’s functions.php file.
6. Use the custom field to render the React app in your WordPress theme’s template files.
7. Test and make sure the React app is working correctly on your site.

Note:

• You may need Node.js and npm installed on your server to use the Create React App plugin.
• If you’re familiar with React development, you can also integrate React into WordPress using the WP REST API, which allows you to fetch data from the WordPress database and use it in your React components.

It’s advisable to have a good knowledge of WordPress, React and JavaScript development before trying to integrate React into your WordPress site.
