Checking if a value exists in localStorage while using AngularJS routing is a simple task

Web tutorials often complicate angularJS conditional routings with strange and complex logic...

I'm looking for something simpler:

Just one component to check if localStorage has authFlag set to true, and then do something like this:

app.config(function ($routeProvider) {
  $routeProvider
      .when('/', {
          templateUrl: 'views/app.html',
          controller: 'AppCtrl'
      })
      .when('/articles', {
          templateUrl: 'views/articles.html',
          controller: 'ArticlesCtrl',
          conditions: { isAuth }
      })
      .otherwise({
          redirectTo: '/'
      });
});

What is the best way to achieve this? Checking if authFlag is in localStorage, and if not, redirect to '/'?

To ensure proper functionality, it is imperative to include a resolve in your code. Within the resolve function, carefully inspect the local storage and direct the route to "/" if necessary:

For optimal results, insert the following lines of code within the resolve function:

resolve:{
    data:  function(){
        var result = window.localStorage.getItem("authFlag");

        if (result)
        {
            // Implement desired actions here
        }
        else
        {
            $location.path("/");
        }
    }
},
