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

///

## Esperar mensajes y enviar mensajes

En tu ruta de WebSocket puedes `await` para recibir mensajes y enviar mensajes.

{* ../../docs_src/websockets/tutorial001.py hl[48:52] *}

Puedes recibir y enviar datos binarios, de texto y JSON.

## Pruébalo

Mas ele ainda faz parte da mesma aplicação/web API **FastAPI** (faz parte do mesmo "pacote Python").

Você pode criar as *operações de rotas* para esse módulo usando o `APIRouter`.

### Importar `APIRouter`

você o importa e cria uma "instância" da mesma maneira que faria com a classe `FastAPI`:
