- Get working code on a personal branch with tests before you submit a PR.
- OkHttp is a small and light dependency.  Don't introduce new dependencies or major new functionality.

**FastAPI**와 함께 원하는 어떤 템플릿 엔진도 사용할 수 있습니다.

일반적인 선택은 Jinja2로, Flask와 다른 도구에서도 사용됩니다.

설정을 쉽게 할 수 있는 유틸리티가 있으며, 이를 **FastAPI** 애플리케이션에서 직접 사용할 수 있습니다(Starlette 제공).

## 의존성 설치

가상 환경을 생성하고(virtual environment{.internal-link target=_blank}), 활성화한 후 jinja2를 설치해야 합니다:


<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

## 사용하기 `Jinja2Templates`

* `Jinja2Templates`를 가져옵니다.
