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.
