브라우저 클라이언트로 데이터를 스트리밍하려면 **Server-Sent Events**(SSE)를 사용할 수 있습니다.

이는 [JSON Lines 스트리밍](stream-json-lines.md)과 비슷하지만, 브라우저가 기본적으로 [`EventSource` API](https://developer.mozilla.org/en-US/docs/Web/API/EventSource)를 통해 지원하는 `text/event-stream` 형식을 사용합니다.

# WebSockets { #websockets }

**FastAPI**で[WebSockets](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API)が使用できます。

## `websockets`のインストール { #install-websockets }

[仮想環境](../virtual-environments.md)を作成し、それを有効化してから、「WebSocket」プロトコルを簡単に使えるようにするPythonライブラリの`websockets`をインストールしてください。

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

## WebSockets クライアント { #websockets-client }

This includes work such as compiling, testing and documenting software, plus sharing that software via publishing and dependency management.
This platform is agnostic to what kind of software is being developed.
It might be Java or Kotlin libraries running on the JVM, Gradle plugins, Android or iOS applications, C++ libraries, and so on.

This platform does not provide special support for a particular language or ecosystem.

* その後、`response` を返す前にさらに `response` を変更することもできます。

**Pydantic v2**의 이 기능 덕분에 API 문서는 더 **정밀**해지고, 자동 생성된 클라이언트와 SDK가 있다면 그것들도 더 정밀해져서 더 나은 **developer experience**와 일관성을 제공할 수 있습니다. 🎉

## 스키마를 분리하지 않기 { #do-not-separate-schemas }

이제 어떤 경우에는 **입력과 출력에 대해 같은 스키마를 사용**하고 싶을 수도 있습니다.
