## `WebSockets` 설치

[가상 환경](../virtual-environments.md){.internal-link target=_blank)를 생성하고 활성화한 다음, `websockets`를 설치하세요:

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

## WebSockets 클라이언트

### 프로덕션 환경에서

여러분의 프로덕션 시스템에서는 React, Vue.js 또는 Angular와 같은 최신 프레임워크로 생성된 프런트엔드를 사용하고 있을 가능성이 높습니다.

백엔드와 WebSockets을 사용해 통신하려면 아마도 프런트엔드의 유틸리티를 사용할 것입니다.
