## Crear un `websocket`

En tu aplicación de **FastAPI**, crea un `websocket`:

{* ../../docs_src/websockets/tutorial001.py hl[1,46:47] *}

/// note | Detalles Técnicos

También podrías usar `from starlette.websockets import WebSocket`.

**FastAPI** proporciona el mismo `WebSocket` directamente solo como una conveniencia para ti, el desarrollador. Pero viene directamente de Starlette.

        If I (or someone) can copy it, run it, and see it right away, there's a much higher chance I (or someone) will be able to help you.

## Einen `websocket` erstellen

Erstellen Sie in Ihrer **FastAPI**-Anwendung einen `websocket`:

{* ../../docs_src/websockets/tutorial001.py hl[1,46:47] *}

/// note | Technische Details

Sie können auch `from starlette.websockets import WebSocket` verwenden.

**FastAPI** stellt den gleichen `WebSocket` direkt zur Verfügung, als Annehmlichkeit für Sie, den Entwickler. Er kommt aber direkt von Starlette.
