Current behaviour

Server can disconnect a client only without reason

io.on('connection', (socket) => {
  setTimeout(() => socket.disconnect(true), 5000);
});

Steps to reproduce (if the current behaviour is a bug)

Note: the best way to get a quick answer is to provide a failing test case, by forking the following fiddle for example.

Expected behaviour

I'm looking for a way to disconnect a client with some reason (on the server), for example:

• connection session time exceeded
• user-token has become invalid
• or something else

in the end I would like to have something like this:

//server
io.on('connection', (socket) => {
  setTimeout(() => {
     socket.disconnect(true, 'My super reason why the connection has been disconnected')
  }, 5000);
});

//client
socket.on('disconnect', (reason) => {
  // reason === 'My super reason why the connection has been disconnected'
});

please let me know if you are going to add the feature in future, or maybe there are any problems to implement it.

Setup
