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

```python
from fastapi import WebSocket
```

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`.
