Speed up WordPress / WooCommerce on none commerce pages

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!
