## `websocket` を作成する { #create-a-websocket }

**FastAPI** アプリケーションで、`websocket` を作成します。

{* ../../docs_src/websockets_/tutorial001_py310.py hl[1,46:47] *}

/// note | 技術詳細

`from starlette.websockets import WebSocket` を使用しても構いません.

**FastAPI** は開発者の利便性のために、同じ `WebSocket` を提供します。しかし、こちらはStarletteから直接提供されるものです。

/// note | 技術細節

你也可以使用 `from starlette.middleware.cors import CORSMiddleware`。

**FastAPI** 在 `fastapi.middleware` 中提供了幾個中介軟體，做為開發者的便利性。但多數可用的中介軟體其實直接來自 Starlette。

第一步是安裝 FastAPI。

確保你建立一個[虛擬環境](../virtual-environments.md)，啟用它，然後**安裝 FastAPI**：

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

/// note | 注意

當你使用 `pip install "fastapi[standard]"` 安裝時，會包含一些預設的可選標準依賴項，其中包括 `fastapi-cloud-cli`，它可以讓你部署到 [FastAPI Cloud](https://fastapicloud.com)。

如果你不想包含那些可選的依賴項，你可以改為安裝 `pip install fastapi`。
