localStorage is not defined (Angular Universal)

Question

I am using universal-starter as backbone.

When my client starts, it read a token about user info from localStorage.

@Injectable()
export class UserSe         


        

Answer 1

I don't think this is a good solution, but I was stucked with the same problem using aspnetcore-spa generator and solved it this way:

@Injectable()
export class UserService {
  foo() {}

  bar() {}

  loadCurrentUser() {
    if (typeof window !== 'undefined') {
       const token = localStorage.getItem('token');
    }

    // do other things
  };
}

This condition prevents client code from running on the server-side where 'window' object doesn't exist.
