Wir werden diesen `APIRouter` in die Hauptanwendung `FastAPI` einbinden, aber zuerst kümmern wir uns um die Abhängigkeiten und einen anderen `APIRouter`.

## Abhängigkeiten

Wir sehen, dass wir einige Abhängigkeiten benötigen, die an mehreren Stellen der Anwendung verwendet werden.

Also fügen wir sie in ihr eigenes `dependencies`-Modul (`app/dependencies.py`) ein.

### Return values { #return-values }

And they can return values or not, the values won't be used.

So, you can reuse a normal dependency (that returns a value) you already use somewhere else, and even though the value won't be used, the dependency will be executed:
