  • i think u are facing this issue in universal ( server side rendering ) only and not in browser, right ? – Dhyey Nov 09 '17 at 08:09
  • I'm running directly from Visual Studio, it is not deployed to the server. So, not sure. How can I check this and let you know correct answer ? – Danijel Boksan Nov 09 '17 at 08:13
  • Aren't you compiling and running it in browser ? Line 10 in [this file](https://github.com/danijel88/AngularPDM/blob/master/AngularPDM/ClientApp/app/components/_guards/auth.guard.ts) is causing the error. – Dhyey Nov 09 '17 at 08:15

You need use "isPlatformBrowser"

Import:

import { isPlatformServer, isPlatformBrowser } from '@angular/common';

and declare in the constructor:

constructor(private _http: Http, @Inject(PLATFORM_ID) private platformId: Object)...

use:

public setValue(value){

    if (isPlatformBrowser(this.platformId)) {
            localStorage.setItem('varX', value);
            ........
        }
}
