특별한 클래스를 만들지 않아도 되며, 이러한 것 혹은 비슷한 종류를 **FastAPI**에 "등록"하기 위해 어떤 곳에 넘겨주지 않아도 됩니다.

단순히 `Depends`에 넘겨주기만 하면 되며, **FastAPI**는 나머지를 어찌할지 알고 있습니다.

## `Annotated`인 의존성 공유하기 { #share-annotated-dependencies }

위의 예제에서 몇몇 작은 **코드 중복**이 있다는 것을 보았을 겁니다.

`common_parameters()`의존을 사용해야 한다면, 타입 명시와 `Depends()`와 함께 전체 매개변수를 적어야 합니다:

```Python
commons: Annotated[dict, Depends(common_parameters)]
