AngularJS. Resolve auth object before routing occurs. Allows to check user authentication before page is shown. The trick is to suppress new value into resolve array for each $routeProvider.when automatically (inside $rootScope.$on "$routeChangeStart")

resolve_auth_before_route.coffee

    .run(['$rootScope', '$location', 'Auth', ($rootScope, $location, Auth) ->

      $rootScope.$on "$routeChangeStart", (event, next, current) ->

        redirectPath = $location.path()

        console.debug "Route change started.", next, current, next.access, Auth.isLoggedIn()

        _authorize = () ->
          if next.access != undefined
            if not Auth.isLoggedIn()
              Auth.authorize().then(
                (user) ->
                  if not user or not Auth.hasAccess(next.access, user)
                    Auth.logout()
                    $location.path('/login').search( 'redirectPath': redirectPath )
                  user
              )
            else if not Auth.hasAccess(next.access)
              Auth.logout()
              $location.path('/login').search( 'redirectPath': redirectPath )

        next.resolve = angular.extend( next.resolve || {}, {
          profile: _authorize
        });
