Hello Bran,
I am trying to integrate your solution here to the Rails integrated realtime-rails solution from Mike Atlas
http://mikeatlas.github.io/realtime-rails/

the challenge i am running into is that the socket interface is already being created outside of the angular code:

<script type='text/javascript'>

window.realtime = {};
window.realtime.messageQueue = [];
window.realtime.enabled = false;

I have tried to point. the socket in your service declaration to window.realtime.socketIo (my appis called headcount)

https://github.com/dreadstar/headcount_app5/blob/master/app/assets/javascripts/angular/services.js.coffee (although this is a coffescript file i am actually forcing javascript)

headcount.factory('socket', function ($rootScope) {
// var socket = io.connect();
// var socket = io.connect("http://localhost:5001");
var socket = window.realtime.socketIo;
return {
on: function (eventName, callback) {
socket.on(eventName, function () {
var args = arguments;
$rootScope.$apply(function () {
callback.apply(socket, args);
});
});
},
emit: function (eventName, data, callback) {
socket.emit(eventName, data, function () {
var args = arguments;
$rootScope.$apply(function () {
if (callback) {
callback.apply(socket, args);
}
});
})
}
};
});

My controller has the following additions to replicate your your example. it is written in coffescript:
https://github.com/dreadstar/headcount_app5/blob/master/app/assets/javascripts/angular/controllers/LocationIndexCtrl.js.coffee

@headcount.controller 'LocationIndexCtrl', ['$scope', '$location', '$http','socket', ($scope, $location, $http, socket) ->
$scope.locs[data.msg.obj.id].current_state= data.msg.obj.current_state
$scope.locs[data.msg.obj.id].fanscnt= data.msg.obj.fanscnt
console.log data

When i switch the EventName to 'realtime_msg' on the server, i can see that my messages are getting to the browser.

you can see the latest version of my code
https://github.com/dreadstar/headcount_app5

Any help would be appreciated.

Thanks,
Tyrone

On the blog post Writing an AngularJS App with Socket.IO the "Open Demo" button leads to a nodejitsu 404 page.

when I run 'node app.js' in console there is an error as below

console.log("Express server listening on port %d in %s mode", app.address().
^
TypeError: Object function app(req, res, next){ app.handle(req, res, next); } has no method 'address'

Hi!

I have an issue with socket.io-service. When it is minificated, it does not work. i'm using SailsJS top of node.

And can you declare where the arguments -variable comes from?
