In your WebSocket route you can `await` for messages and send messages.

{* ../../docs_src/websockets/tutorial001_py39.py hl[48:52] *}

You can receive and send binary, text, and JSON data.

## Try it { #try-it }

If your file is named `main.py`, run your application with:

<div class="termy">

```console
$ fastapi dev main.py

		o.Recursive = o.Separator != slashSeparator
		o.Separator = slashSeparator
	} else {
		// Default is recursive, if delimiter is set then list non recursive.
		o.Recursive = true
