Enqueueing JS/CSS

The base plugin class provides helpers for enqueueing assets from the assets directory.

JavaScript

add_action('wp_enqueue_scripts', function () {
    My_Plugin::instance()->enqueue_js('frontend', ['jquery'], [
        'MyPlugin' => [
            'ajaxUrl' => admin_url('admin-ajax.php'),
        ],
    ]);
});

This loads:

• assets/js/frontend.js

The enqueue_js() method uses wp_localize_script() for each localization array you pass.

CSS

add_action('wp_enqueue_scripts', function () {
    My_Plugin::instance()->enqueue_css('frontend');
});

This loads:

• assets/css/frontend.css

Admin assets

You can enqueue assets through the admin module too:

My_Plugin::instance()->get_admin_module()->enqueue_css('admin');

That expects:

• admin/assets/css/admin.css

because the admin module’s base path is admin/.
