If I manually change the token value in stored in localstorage the UI still sees me as being logged in.

Any chance to update it to latest angular 2.rc.6 ? :)

Well, the page freezes on the loading screen. Checked everything and have no idea.

When i import localStorage is error.
npm install localStorage
by angular2 2.0.0

How to add angular-cli to this project? (sorry, i'm noob)

Please help me to add condition of signature expire in auth.guard. Here, we are only checking the token exist. I want to check whether our token expire and if expire, redirect to login page.

I'm trying to run this example as an Angular CLI app. It uses webpack by default instead of SystemJS. The bundle gets built with no errors, but I've got this error on the page:

metadata_resolver.js:508 Uncaught Error: Can't resolve all parameters for UserService: (Http, ?).

I guess it has something to do with the second argument of UserService constructor, which is of type AuthenticationService: private authenticationService: AuthenticationService.

@cornflourblue Can you please give a clue how to solve this error? I'm a noob in Angular and webpack seems a lot more easier (with literally no configuration) than SystemJS.

Hello,

When I try and run this on my machine (with npm start) I get the following error message:

I just downloaded the example as is from GitHub - is there something else I need to do to run it properly?

Implemented CanActivate to guard the routes, and navigating to /login if the user is not logged in, but i can see it is redirecting with POST request, which results to 404 error.

@Injectable()
export class AuthGuard implements CanActivate {

constructor(private router: Router) { }

canActivate() {
    console.log("canActivate : AuthGuard");
    if (localStorage.getItem('currentUser')) {
        // logged in so return true
        return true;
    }

    // not logged in so redirect to login page
    this.router.navigate(['/login']);
    return false;
}

}
