how to remove particular userid when user disconnected chat

[darrachequesne]

Hi! Could you please explain your issue?

If I understand correctly, you want to disconnect all the session of a particular user, is that right? In that case, you can use the disconnectSockets() method:

io.on("connection", (socket) => {
  socket.join(someUserId);
});

// and then upon disconnection
io.in(someUserId).disconnectSockets();
