Mais vous devez d'abord lire le **Tutoriel - Guide d'utilisation** (ce que vous êtes en train de lire en ce moment).

# WebSockets { #websockets }

Vous pouvez utiliser [WebSockets](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API) avec **FastAPI**.

## Installer `websockets` { #install-websockets }

Vous devez créer un [environnement virtuel](../virtual-environments.md), l'activer, et installer `websockets` (une bibliothèque Python qui facilite l'utilisation du protocole « WebSocket ») :

<div class="termy">

```console
$ pip install websockets

Dies ist ein Low-Level-Erweiterungspunkt.

Wenn Sie nur zusätzliche Responses deklarieren müssen, können Sie dies bequemer mit [Zusätzliche Responses in OpenAPI](additional-responses.md) tun.
