Getting UID from socket.io event & managing events

Stackoverload

What would be the best way to get the UID of the a socket that emitted an event,
EX:
sockets.server.on('SomeEvent', function(data) {
console.log('UID of socket who sent/called that event');
});

On top of that, I'm having trouble listening to events in socket.io, as I'm used to setting up socket.io, and not having pre-setup functions and what not. I'm used to being able to do:
io.on('connection', function(socket) {
//Socket events here
});

but instead I'm supposed to work with sockets.server? How would one go about setting up/listening to events for this?

When you add a listener to one of the modules ('admin', 'categories', 'groups', 'meta', 'modules', 'notifications', 'plugins', 'posts', 'topics', 'user'), additional data is verified and sent.

var socketPlugins = module.parent.require('./socket.io/plugins')

socketPlugins.yourplugin = {

  // This function is now exposed as the event 'plugins.yourplugin.someevent'
  someevent: function (socket, data, callback) {

    // socket.uid is now the verified uid of the user sending the event.
    // data is the object sent with the event.
    console.log("UID " + socket.uid + " sent data:", data);

    // socket.uid is 0 if the user is a guest.
    callback(!socket.uid, {uid: socket.uid});
  }
}

client

socket.emit('plugins.yourplugin.someevent', {somedata: 'somevalue'}, function (err, data) {
  if (!err) console.log("You are UID " + data.uid);
});

I see! Thanks! Is there a Doc for this? I haven't had luck finding anything

I don't think so. I think I just discovered it by examining other plugins and the core code.

@yariplus Ahh, I should do such! Thanks

This would be an excellent addition to our documentation
