Les intégrations et « plug-ins » peuvent être construits en utilisant le système d’**injection de dépendances**. Mais en réalité, il n’y a **pas besoin de créer des « plug-ins »**, car en utilisant des dépendances il est possible de déclarer un nombre infini d’intégrations et d’interactions qui deviennent disponibles pour vos fonctions de chemins d’accès.
