WooCommerce provides great functionality, but loads a lot of resources even if not needed.
If a site loads longer than 5-7 seconds, potential customers already loose interest :)
UNLOAD ALL THAT IS NOT NEEDED
Add this to your functions.php:
add_action( 'wp_enqueue_scripts', 'cleanup_woocommerce_includes', 99 );
function cleanup_woocommerce_includes(){
//check that woo exists
if ( function_exists( 'is_woocommerce' ) ) {
if ( ! is_woocommerce() && ! is_cart() && ! is_checkout() ) {}
/*Styles*/
wp_dequeue_style( 'woocommerce_frontend_styles' );
wp_dequeue_style( 'woocommerce_fancybox_styles' );
wp_dequeue_style( 'woocommerce_chosen_styles' );
wp_dequeue_style( 'woocommerce_prettyPhoto_css' );
wp_dequeue_style( 'woocommerce-layout' );
wp_dequeue_style( 'woocommerce-smallscreen' );
wp_dequeue_style( 'woocommerce-general' );
wp_dequeue_style( 'wc-bto-styles' );
/*Scripts*/
wp_dequeue_script( 'wc-cart' );
wp_dequeue_script( 'wc-cart-fragments' );
wp_deregister_script( 'wc-add-to-cart' );
wp_dequeue_script( 'wc-add-to-cart' );
wp_deregister_script( 'wc-add-to-cart-variation' );
wp_dequeue_script( 'wc-add-to-cart-variation' );
wp_dequeue_script( 'wc-checkout' );
wp_dequeue_script( 'wc-single-product' );
wp_dequeue_script( 'jquery-blockui' );
wp_dequeue_script( 'wc_price_slider' );
wp_dequeue_script( 'wc-chosen' );
wp_dequeue_script( 'woocommerce' );
wp_dequeue_script( 'prettyPhoto' );
wp_dequeue_script( 'prettyPhoto-init' );
wp_dequeue_script( 'jquery-placeholder' );
wp_dequeue_script( 'fancybox' );
wp_dequeue_script( 'jqueryui' );
}
}
}
Like always, make sure that nothing breaks. If things break or are required by certain pages add an exception for that!
