Just detect front end js and css

Hi @sonisitez

Could you please try the following code:

<?php

add_action( 'plugins_loaded', function() {
	if ( ! class_exists( 'Hummingbird\\WP_Hummingbird' ) ) {
		return; // Hummingbird is not installed/enabled.
	}

	if ( ! class_exists( 'Hummingbird_Non_Frontend_Assets_Excluder' ) ) {
		class Hummingbird_Non_Frontend_Assets_Excluder {
			private static $instance;
			private $excluded_handles = array();

			// Set this to TRUE to prevent minify and combine the
			// excluded items (Use only if you know what you are doing).
			const PREVENT_MINIFY_AND_COMBINE = FALSE;

			public static function get() {
				if ( null === self::$instance ) {
					self::$instance = new self();
				}
				return self::$instance;
			}

			public function __construct() {
				add_filter( 'wphb_minification_display_enqueued_file', array( $this, 'should_display_enqueued_file' ), 10, 3 ); 
				if ( self::PREVENT_MINIFY_AND_COMBINE ) { 
					add_filter( 'wphb_minify_resource', array( $this, 'should_minify_resource' ), 10, 4 );
					add_filter( 'wphb_combine_resource', array( $this, 'should_combine_resource' ), 10, 3 );
				}
			}

			private function is_frontend_asset( $src ) {
				$current_theme_dir = get_template_directory();
				$current_theme_url = get_template_directory_uri();
		
				if ( false !== strpos( $src, basename( WP_CONTENT_DIR ) . '/themes' ) && 0 !== strpos( $src, $current_theme_dir ) && 0 !== strpos( $src, $current_theme_url ) ) {
					return false; // Non-active theme assets.
				}
				if ( false !== strpos( $src, '/wp-includes/' ) || false !== strpos( $src, '/wp-admin/' ) ) {
					return false; // Admin assets.
				}
		
				return true;
			}

			public function should_display_enqueued_file( $value, $item, $type ) {
				if ( ! $this->is_frontend_asset( $item['src'] ) ) {
					$this->excluded_handles[ $item['handle'] ] = $type;
					return false;
				}
				return $value;
			}

			public function should_minify_resource( $value, $handle, $type, $url ) {
				if ( ! $this->is_frontend_asset( $url ) ) {
					$this->excluded_handles[ $handle ] = $type;
					return false;
				}
				return $value;
			}

			public function should_combine_resource( $value, $handle, $type ) {
				if ( isset( $this->excluded_handles[ $handle ] ) ) {
					return false;
				}
				return $value;
			}
		}
		Hummingbird_Non_Frontend_Assets_Excluder::get();
	}
});

Add it as a mu-plugin:

https://wpmudev.com/docs/using-wordpress/installing-wordpress-plugins/#installing-mu-plugins then re-check the Assets files, it will prevent those unwished files from getting in Assets Optimization.

Hi @sonisitez

Thank you for response!

My colleague already forwarded this suggestion to our Hummingbird Team so developers will look into it.

We are constantly working on improving the plugin and this sounds like a really nice thing to implement. I don’t have ETA but it will surely be looked into and taken into consideration with future updates.

Best regards,
Adam

Hello @sonisitez !

Thank you for the additional feedback! We’ll pass it over to our Hummingbird team for further review as well.

Kind regards,
Pawel
