angular authentication and routing

cancel_route

In case you want to do authentication and redirection, depending on whether user is logged in or not,
you can do it by listening $routeChangeStart event.
This way, you don't need to use additional plugins, 
or to add 'resolve' parameters to your routes (which can be difficult to maintain).

In following example, if non-logged user tries to reach authenticated route, user will be redirected to login page.
If logged user tries to reach login/register page, user will be redirected to home page.

$rootScope.$on('$routeChangeStart', function(event, next, current){
  if(AuthFactory.isAuthenticated()){
    if(AuthFactory.isAuthRoute(next.originalPath)){
      $route.reload();
      $location.path('/');
    }       
  } else {
    if(!AuthFactory.isAuthRoute(next.originalPath)){
      $route.reload();
      $location.path('/login');
    }
  }
});
