AngularJS: Protecting routes with angularjs depending if the user is authorized?

Question

I have just started out working with an AngularJS app I\'m developing, everything is going well but I need a way of protecting routes so that a user wouldn\'t b

Answer 1

Another way of using the resolve attribute of the $routeProvider:

angular.config(["$routeProvider",
function($routeProvider) {

  "use strict";

  $routeProvider

  .when("/forbidden", {
    /* ... */
  })

  .when("/signin", {
    /* ... */
    resolve: {
      access: ["Access", function(Access) { return Access.isAnonymous(); }],
    }
  })

  .when("/home", {
    /* ... */
    resolve: {
      access: ["Access", function(Access) { return Access.isAuthenticated(); }],
    }
  })

  .when("/admin", {
    /* ... */
    resolve: {
      access: ["Access", function(Access) { return Access.hasRole("ADMIN"); }],
    }
  })

  .otherwise({
    redirectTo: "/home"
  });

}]);

This way, if Access does not resolve the promise, the $routeChangeError event will be fired:

angular.run(["$rootScope", "Access", "$location",
function($rootScope, Access, $location) {

  "use strict";

  $rootScope.$on("$routeChangeError", function(event, current, previous, rejection) {
    if (rejection == Access.UNAUTHORIZED) {
      $location.path("/login");
    } else if (rejection == Access.FORBIDDEN) {
      $location.path("/forbidden");
    }
  });

}]);
