    When a user disconnects from a Socket.IO connection, you can send data from the client-side to the server-side by emitting an event just before the disconnection event occurs. The key is to send the data before the connection is fully closed. Here’s how you can achieve this:

    // Emit an event with data just before disconnecting

    socket.emit('disconnecting', { someData: 'This is some data' });

    // Disconnect from the server

    socket.disconnect();

    On client side, you can use

    window.addEventListener('unload',()=>{
//Emit websocket/socket.io event here
})
