AngularJS | handle routing before they load

Question

I wish to create a simple authentication check for my routes by external service.

I define the access requirements on the route object:

$routeProvide

My solution was combining $locationChangeStart and $routeChangeStart:

$rootScope.$on('$locationChangeStart', function (event) {
    //If login data not available, make sure we request for it
    if($facebook.isConnected()==null) {
        $facebook.getLoginStatus();
        event.preventDefault();
        return;
    }

    var next=parseRoute().$$route;
    if(!Auth.loginCheck(next))
        event.preventDefault();
});

I copied parseRoute() from angular-route.js to parse the given URL to route..

Then I build my login check handler(Auth.loginCheck) in a way that if it fail it return false.

I also use $routeChangeStart to handle $route.reload() events, so now after every change within my authentication status I just do $route.reload():

$rootScope.$on('$routeChangeStart', function (event, next) {
    Auth.loginCheck(next);
});

Finally I just make sure that this custom service is always will run by using simple run() method.

Edit:

We now using ngAuth, a module we designed to solve that exact problem(based on the answer I gave here before).

At last, we developed a angular-module that solved this issue.. This module is based on the answer I published here before.

Due the requests here, we published a beta release that works now: http://github.com/GoDisco/ngAuth

Feel free to use it.
