Service to get info from URL 

drush eval "print_r(\Drupal::service('smart_link')->getUrlInfo($url))"

Services are loaded when necessary and easy to access in other modules.

To turn the previous code into a service, first we need to set up a services file.

smart_link.services.yml

services:
  smart_link:
    class: Drupal\smart_link\SmartLink

Then we need the service class.

smart_link/src/SmartLink.php

<?php

namespace Drupal\smart_link;

use Masterminds\HTML5;

/**
 * SmartLink service.
 */
class SmartLink {

  /**
   * The Masterminds/HTML5 library.
   *
   * @var HTML5
   */
  protected $html5;

  /**
   * Constructs a SmartLinkService object.
   */
  public function __construct() {
    $this->html5 = new HTML5();
  }

  /**
   * Get URL info.
   */
  public function getUrlInfo($url) {
    $page = $this->html5->load($url);
    
    $meta = [];
    $description = '';
    foreach ($page->getElementsByTagName('meta') as $meta_element) {
      if ($meta_element->getAttribute('name') == 'description') {
        $description = $meta_element->getAttribute('content');
      }
      $meta[] = simplexml_import_dom($meta_element)->asXML();
    }

    return [
      'domain' => parse_url($url)['host'],
      'path' => parse_url($url)['path'],
      'description' => $description,
      'title' => $page->getElementsByTagName('title')[0]->textContent,
      'h1' => $page->getElementsByTagName('h1')[0]->textContent,
      'meta' => implode("\n", $meta),
    ];
  }

}

 

Call the function from drush

drush eval "print_r(\Drupal::service('smart_link')->getUrlInfo($url))"
