# WebSockets

您可以在 **FastAPI** 中使用 [WebSockets](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API)。

## 安装 `WebSockets`

首先，您需要安装 `WebSockets`：

```console
$ pip install websockets

---> 100%
```

## WebSockets 客户端

### 在生产环境中

在您的生产系统中，您可能使用现代框架（如React、Vue.js或Angular）创建了一个前端。

要使用 WebSockets 与后端进行通信，您可能会使用前端的工具。

或者，您可能有一个原生移动应用程序，直接使用原生代码与 WebSocket 后端通信。

或者，您可能有其他与 WebSocket 终端通信的方式。
