어떤 이유로 코드에서 `|`를 사용할 수 없다면, 예를 들어 타입 어노테이션이 아니라 `response_model=` 같은 곳이라면, 파이프 문자(`|`) 대신 `typing`의 `Union`을 사용할 수 있습니다.

예를 들어, 어떤 값이 `str` 또는 `None`이 될 수 있다고 선언할 수 있습니다:

```python
from typing import Union


def say_hi(name: Union[str, None]):
        print(f"Hi {name}!")
```

`typing`에는 `None`이 될 수 있음을 선언하는 축약형으로 `Optional`도 있습니다.

아주 개인적인 관점에서의 팁입니다:

따라서 데이터가 올바른 유형인지 확인해야 합니다. 예: `JSONResponse`를 반환하는 경우, JSON과 호환되는지 확인하세요.

또한 `response_model`로 필터링되어야 했던 데이터를 전송하지 않도록 하세요.

`from starlette.responses import Response` 또는 `from starlette.responses import JSONResponse`를 사용할 수도 있습니다.

**FastAPI**는 개발자의 편의를 위해 `fastapi.responses`로 동일한 `starlette.responses`를 제공합니다. 하지만 사용 가능한 대부분의 응답은 Starlette에서 직접 제공됩니다.

It will install all the dependencies and your local FastAPI in your local environment.

### Using your local FastAPI

If you create a Python file that imports and uses FastAPI, and run it with the Python from your local environment, it will use your cloned local FastAPI source code.

And if you update that local FastAPI source code when you run that Python file again, it will use the fresh version of FastAPI you just edited.

- MinIO exports Prometheus compatible data by default as an authorized endpoint at `/minio/v2/metrics/cluster`. 
- MinIO exports Prometheus compatible data by default which is bucket centric as an authorized endpoint at `/minio/v2/metrics/bucket`.

This document explains how to setup Prometheus and configure it to scrape data from MinIO servers.
