## Dependency Injection

Using `BackgroundTasks` also works with the dependency injection system, you can declare a parameter of type `BackgroundTasks` at multiple levels: in a *path operation function*, in a dependency (dependable), in a sub-dependency, etc.

### Einbringen von Abhängigkeiten (Dependency Injection)

FastAPI enthält ein extrem einfach zu verwendendes, aber extrem mächtiges <abbr title='Dependency Injection – Einbringen von Abhängigkeiten: Auch bekannt als Komponenten, Resourcen, Dienste, Dienstanbieter'><strong>Dependency Injection</strong></abbr> System.

Es erreicht etwas Ähnliches wie Flask-apispec.

Es verfügt über ein integriertes Dependency Injection System, welches von Angular 2 inspiriert ist. Erfordert ein Vorab-Registrieren der „Injectables“ (wie alle anderen Dependency Injection Systeme, welche ich kenne), sodass der Code ausschweifender wird und es mehr Codeverdoppelung gibt.
