Execute python code when a browser session ends.

[mtanco]

I have a shared application where users can import a file for use with generative ai tasks. When they are done with the app, I would like the delete the file. Ideally, I would have a function (with access to q) which could run on 2023/11/10 15:42:14 # {"addr":"[::1]:49266","t":"ui_drop"} events. Today, we get this notification in the Wave Server logs, but not in our python code at all.

I could maybe use the on_shutdown function and do one big clean up when the app is killed, but this doesn't have access to q and also we're then paying for storage of unneeded files until we pause / kill the app.

Help!

@on("@system.client_disconnect")
async def on_client_disconnect(q: Q):
    print("DISCONNECTED")

I struggled to find this in docs, but found it in discussions!

Glad you found it and proved the point of having centralized public knowledge base at hand :)

The feature is documented here, but feel free to suggest a more discoverable location.
