이러한 경우, 데이터를 응답에 전달하기 전에 `jsonable_encoder`를 사용하여 변환할 수 있습니다:

{* ../../docs_src/response_directly/tutorial001.py hl[6:7,21:22] *}

/// note | 기술적 세부 사항

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

**FastAPI**는 개발자의 편의를 위해 `starlette.responses`를 `fastapi.responses`로 제공합니다. 그러나 대부분의 가능한 응답은 Starlette에서 직접 제공합니다.

## 사용자 정의 `Response` 반환하기

**Typer**는 FastAPI의 동생입니다. 그리고 **FastAPI의 CLI**가 되기 위해 생겼습니다. ⌨️ 🚀

## 요구사항

FastAPI는 거인들의 어깨 위에 서 있습니다:

* 웹 부분을 위한 <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a>.
* 데이터 부분을 위한 <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a>.

## 설치
