A little WordPress function for micromanaging what, where, and when scripts and styles load.

micromanage-assets.php

// Deregister all the things
add_action( 'wp_print_scripts', 'libux_deregister_scripts', 100 );

function libux_deregister_scripts() {
  
  // Ditch jQuery - except on one page that requires it,
  // but load that with a CDN.
  wp_deregister_script( 'jquery' );
  
  if ( is_page( 'something' ) ) {
		wp_enqueue_script( 'jquery', '//cdnjs.cloudflare.com/ajax/libs/jquery/1.11.1/jquery.min.js', true );
		wp_enqueue_script('plugin-name', plugins_url( /* url */ ), array('jquery'), true); 
  }

}

add_action( 'wp_print_styles', 'libux_deregister_styles', 100 );
function libux_deregister_styles() {
  
  // Unless we're on a page where this plugin is used,
  // don't by god load that CSS.
	if ( !is_page( 'something' ) ) {
		
		wp_deregister_style( 'plugin-name' );
		
	}

}
