### 당신만의 비동기 코드 작성하기

Starlette(그리고 FastAPI)는 <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a>를 기반으로 하고있고, 따라서 파이썬 표준 라이브러리인 <a href="https://docs.python.org/3/library/asyncio-task.html" class="external-link" target="_blank">asyncio</a> 및 <a href="https://trio.readthedocs.io/en/stable/" class="external-link" target="_blank">Trio</a>와 호환됩니다.

Underneath, in the ASGI technical specification, this is part of the <a href="https://asgi.readthedocs.io/en/latest/specs/lifespan.html" class="external-link" target="_blank">Lifespan Protocol</a>, and it defines events called `startup` and `shutdown`.

/// info

You can read more about the Starlette `lifespan` handlers in <a href="https://www.starlette.dev/lifespan/" class="external-link" target="_blank">Starlette's  Lifespan' docs</a>.

Por baixo, na especificação técnica do ASGI, isso é parte do <a href="https://asgi.readthedocs.io/en/latest/specs/lifespan.html" class="external-link" target="_blank">Protocolo Lifespan</a>, e define eventos chamados `startup` e `shutdown`.

/// info | Informação

データを受け取り、 `application/json` としてエンコードされたレスポンスを返します。

上で読んだように、**FastAPI** のデフォルトのレスポンスとして利用されます。

### `ORJSONResponse`

上で読んだように、<a href="https://github.com/ijl/orjson" class="external-link" target="_blank">`orjson`</a>を使った、高速な代替のJSONレスポンスです。

### `UJSONResponse`

<a href="https://github.com/ultrajson/ultrajson" class="external-link" target="_blank">`ujson`</a>を使った、代替のJSONレスポンスです。

                                                       items="${backupItems}">
                                                <tr
                                                        data-href="${contextPath}/admin/backup/download/${f:u(data.id)}/">
                                                    <td>${f:h(data.name)}</td>
                                                </tr>

Y como el `Response` se puede usar frecuentemente para establecer headers y cookies, **FastAPI** también lo proporciona en `fastapi.Response`.
