Disable emoji's

You don't use Emojis in your website ? Then don't load them with this snippet :

/**
 * Disable the emoji's
 */
function disable_emojis() {
 remove_action( 'wp_head', 'print_emoji_detection_script', 7 );
 remove_action( 'admin_print_scripts', 'print_emoji_detection_script' );
 remove_action( 'wp_print_styles', 'print_emoji_styles' );
 remove_action( 'admin_print_styles', 'print_emoji_styles' ); 
 remove_filter( 'the_content_feed', 'wp_staticize_emoji' );
 remove_filter( 'comment_text_rss', 'wp_staticize_emoji' ); 
 remove_filter( 'wp_mail', 'wp_staticize_emoji_for_email' );
 add_filter( 'tiny_mce_plugins', 'disable_emojis_tinymce' );
 add_filter( 'wp_resource_hints', 'disable_emojis_remove_dns_prefetch', 10, 2 );
}
add_action( 'init', 'disable_emojis' );

/**
 * Filter function used to remove the tinymce emoji plugin.
 * 
 * @param array $plugins 
 * @return array Difference betwen the two arrays
 */
function disable_emojis_tinymce( $plugins ) {
 if ( is_array( $plugins ) ) {
 return array_diff( $plugins, array( 'wpemoji' ) );
 } else {
 return array();
 }
}

/**
 * Remove emoji CDN hostname from DNS prefetching hints.
 *
 * @param array $urls URLs to print for resource hints.
 * @param string $relation_type The relation type the URLs are printed for.
 * @return array Difference betwen the two arrays.
 */
function disable_emojis_remove_dns_prefetch( $urls, $relation_type ) {
 if ( 'dns-prefetch' == $relation_type ) {
 /** This filter is documented in wp-includes/formatting.php */
 $emoji_svg_url = apply_filters( 'emoji_svg_url', 'https://s.w.org/images/core/emoji/2/svg/' );

$urls = array_diff( $urls, array( $emoji_svg_url ) );
 }

return $urls;
}

Disable Jquery Migrate

It's loaded by default with Worpdress, and in most case, it's not useful.

function dequeue_jquery_migrate( $scripts ) {
    if ( ! is_admin() && ! empty( $scripts->registered['jquery'] ) ) {
        $scripts->registered['jquery']->deps = array_diff(
            $scripts->registered['jquery']->deps,
            [ 'jquery-migrate' ]
        );
    }
}
add_action( 'wp_default_scripts', 'dequeue_jquery_migrate' );

Disable Embeds

If you don't have a blog or you just don't have to "embed" anything, you can also disable this feature.

function my_deregister_scripts(){
 wp_dequeue_script( 'wp-embed' );
}
add_action( 'wp_footer', 'my_deregister_scripts' );
