It is provided directly by Starlette, but you can import it from `fastapi`:

```python
from fastapi import WebSocket

/// tip

When you want to define dependencies that should be compatible with both HTTP and WebSockets, you can define a parameter that takes an `HTTPConnection` instead of a `Request` or a `WebSocket`.

Vamos supor que o arquivo dedicado a lidar apenas com usuários seja o submódulo em `/app/routers/users.py`.

Você quer manter as *operações de rota* relacionadas aos seus usuários separadas do restante do código, para mantê-lo organizado.

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`.
