Answer 1

You should use { tokenNotExpired } 'angular2-jwt'; You will need following implementation:

Inside your app.module.ts

import { tokenNotExpired } from 'angular2-jwt';
. 
.
.
 @NgModule({

      providers: [
       .
       .
       { provide: 'tokenNotExpired', useValue: tokenNotExpired }, 
      ]

 })

and Inside your service where you need to check if toker is expired or not:

constructor( @Inject('tokenNotExpired') private tokenNotExpired)

isTokenExpired(idToken){
    return this.tokenNotExpired(idToken);
}

Answer 2

Use tokenNotExpired('id_token')
