Drupal 8 programtic custom error page

This is for Drupal 8.

The snippet was taken from axelerant.com.

Basically we're feeding drupal a theme hook suggestion if there is an HTTP error.

The snippet was one of two suggestions. The other one follows.

/**
 * Implements hook_theme_suggestions_HOOK_alter().
 */
function THEMENAME_theme_suggestions_page_alter(array &$suggestions, array $variables) {

  $route_name = \Drupal::routeMatch()->getRouteName();
  switch ($route_name) {
    case 'system.401':
      // Unauthorized Access.
      $error = 401;
      break;

    case 'system.403':
      // Access Denied.
      $error = 403;
      break;

    case 'system.404':
      // Page Not Found.
      $error = 404;
      break;
  }
  if (isset($error)) {
    $suggestions[] = 'page__' . $error;
  }
}
