Authentication redirect for angular-fullstack yeoman generator

angular-fullstack-redirect.js

// The Yeoman angular-fullstack generator allows for authentication to be required
// when a user goes to a given route.  To enable this behavior, add 
authenticate: true 
// to your /client/app/<routename>/<routename>.js file, in the .when routing block.
// like this:
angular.module('meanApp')
  .config(function ($routeProvider) {
    $routeProvider
      .when('/', {
        templateUrl: 'app/main/main.html',
        controller: 'MainCtrl',
        authenticate: true   //  Require Authentication for this route
      });
  });

// This works well enough, but after authentication you are redirected back to the root 
// of your site.  If you want to store the intended url and redirect to it, follow the 
// steps beloow.

// Note: For Angular v1.4 and greater you may need to replace all instances of
// $cookieStore with $cookies, depending on your version of ngCookies

// 1. store the url to return to in a cookie within the '.run()' method of `client/app/app.js`
// Note: You must add $cookieStore to the .run function parameter list
        .run(function ($rootScope, $location, Auth, $cookieStore) {
        // Redirect to login if route requires auth and you're not logged in
        $rootScope.$on('$stateChangeStart', function (event, next) {
          Auth.isLoggedInAsync(function(loggedIn) {
            if (next.authenticate && !loggedIn) {
    
              // store the requested url if not logged in
              if ($location.url() != '/login')
              {
                $cookieStore.put('returnUrl', $location.url());
              }
              $location.path('/login');
            }
          });
        });
      });

 // 2. for Oauth, check for this cookie and redirect if it exists in `server/auth/auth.service.js`
    function setTokenCookie(req, res) {
      if (!req.user) { 
        return res.json(404, { message: 'Something went wrong, please try again.'}); 
      }
      
      var token = signToken(req.user._id, req.user.role);
      res.cookie('token', JSON.stringify(token));
    
      // return the user to the request page (oAuth) or homepage
      if (typeof req.cookies.returnUrl != 'undefined')
      {
          res.redirect(req.cookies.returnUrl.replace(/"/g, "") || '/');
      }
      else
      {
        res.redirect('/');
      }
    }

 // 3. for local login, edit `client/app/account/login/login.controller.js`
 // Add $cookieStore to the .controller function parameters:
 .controller('LoginCtrl', function ($scope, Auth, $location, $window, $cookieStore) {

// 4. Then check for cookie in the `.then()` part of `$scope.login()`, file: 
    .then( function() {
              // Logged in, redirect to home
              if (typeof $cookieStore.get('returnUrl') != 'undefined' && $cookieStore.get('returnUrl') != '')
              {
                $location.path($cookieStore.get('returnUrl'));
                $cookieStore.remove('returnUrl');
              }
              else
              {
                $location.path('/');
              }
            })
