Angular2-jwt: JwtHelperService does not work when using promise

Created on 19 Jun 2019 · 11Comments · Source: auth0/angular2-jwt

Description

I'm trying to use jwtOptionsFactory to handle getting token from ngrx store.

The interceptor works just fine, but when I try to us JwtHelperService without passing token (I guess it uses tokengetter by default) or with passing token via this.jwtHelperService.tokenGetter() does not work because my factory return promise while the method from service tries run split method on promise, not on string...

My code:

function jwtOptionsFactory(store: Store<any>): object {
  return {
    whitelistedDomains: ['localhost:5500'],
    tokenGetter: () => {
      return store.select(FromAppState.selectAuthToken)
        .pipe(take(1))
        .toPromise();
    }
  };
}

@NgModule({
  // ...
  imports: [
    // ...
    JwtModule.forRoot({
      jwtOptionsProvider: {
        provide: JWT_OPTIONS,
        useFactory: jwtOptionsFactory,
        deps: [Store]
      }
    }),
    // ...
  ]
  bootstrap: [AppComponent]
})
export class AppModule {}

  constructor(private dialogService: DialogService,
              private jwtHelperService: JwtHelperService) { }

  ngOnInit(): void {
    console.log(this.jwtHelperService.tokenGetter()); // <= return promise, not string
    console.log(this.jwtHelperService.decodeToken(this.jwtHelperService.tokenGetter()));
    console.log(this.jwtHelperService.isTokenExpired(this.jwtHelperService.tokenGetter()));
    console.log(this.jwtHelperService.getTokenExpirationDate(this.jwtHelperService.tokenGetter()));
  }

error:

Please fix this

Also it would be great if this would also supports Observable
