Zend\Expressive ist das neue Zugpferd am Zend Framework 3 Himmel. Das »PSR-7 Middleware Microframework« verspricht den Aufbau von leichtgewichtigen Webanwendungen innerhalb von wenigen Minuten. Wir werfen in dieser Session einen genaueren Blick auf die Möglichkeiten von Zend\Expressive und betrachten auch den Aufbau von komplexeren Middleware Anwendungen. Zudem erläutern wir die Frage, ob die Tage der MVC Frameworks nun gezählt sind.
