beforeUnload Not Working with Socket.io

[Shivam-Shandilya1]

Before closing the tab or window I ask the user either they want to leave? If they confirms The socket should disconnect otherwise there will be no change.

I am using
"socket.io": "^4.7.5",
"socket.io-client": "^4.7.5",
"socket.io-redis": "^6.1.1",

and Browser: Chrome

But actual result: after closing tab, the socket immediately got disconnected even without listening to the user confirmation.

Hi! The closeOnBeforeunload option controls whether the socket is disconnected when receiving a "beforeunload" event. It now defaults to false since version 4.7.1, which means that the socket won't be automatically disconnected.
