Question

When a user disconnects from the server, how can I find out the session ID?

At the moment I’ve got an ugly method of asking all existing clients to send a message back.

e.g. on the server:

socket.on('disconnect', function() {
    // What’s the sessionid?
});

Answer 1

socket.on('disconnect', function() {
    console.log(this.id);
});

will give you the ID of the socket which was closed, but this is probably more of a hack… 🙂
