# WebSockets { #websockets }

Puedes usar [WebSockets](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API) con **FastAPI**.

## Instalar `websockets` { #install-websockets }

Asegúrate de crear un [entorno virtual](../virtual-environments.md), activarlo e instalar `websockets` (un paquete de Python que facilita usar el protocolo "WebSocket"):

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

        return findPreviousVersion(gitWrapper, version)
            .flatMap(earlierVersion -> gitWrapper.listFiles("v" + earlierVersion, "docs/changelog"))
            .map(line -> Path.of(line).getFileName().toString())
            .collect(Collectors.toSet());
    }
