An example of a simple cli-app that uses Symfony HttpClient in a domain service.
php app.php
$facade = new CommentFacade();
$score = $facade->getSpamScore('Lorem ipsum!');This example shows the simplest flow between Facade -> Factory -> Config.
The SpamChecker is a domain service which depends on a HttpClient and an endpoint,
and those details are handled in the Factory.
The Facade uses the Factory to create that service and immediately use it.
