Hi everyone I am trying to configure my app.module to include Angular2-JWT. I’ve followed Angular2-jwt readme as well converting my storage.get to a promise but I get the following error:

`TypeError: StorageConstructor is not a constructor (evaluating 'new Storage()')`

Can anyone help me with setting this up properly? Thanks in advance.  
_Note I’ve also tried import storage but then get parameter error._

My code looks like this.

```auto
import { BrowserModule } from '@angular/platform-browser';
import { ErrorHandler, NgModule } from '@angular/core';
import { Http, HttpModule } from '@angular/http';
import { IonicApp, IonicErrorHandler, IonicModule } from 'ionic-angular';
import { IonicStorageModule } from '@ionic/storage';
import { AuthHttp, AuthConfig } from 'angular2-jwt';

import { MyApp } from './app.component';
import { HomePage } from '../pages/home/home';
import { LoginPage } from '../pages/login/login';
import { ProfilePage } from '../pages/profile/profile';

import { StatusBar } from '@ionic-native/status-bar';
import { SplashScreen } from '@ionic-native/splash-screen';
import { AuthService } from '../providers/auth/auth.service';
import { AuthResourceService } from '../providers/auth/auth-resource.service';
import { AlertService } from '../providers/alert/alert.service';

let storage = new Storage();

export function getAuthHttp(http) {
  return new AuthHttp(new AuthConfig({
    headerPrefix: 'JWT',
    noJwtError: true,
    globalHeaders: [{'Accept': 'application/json'}],
    tokenGetter: (() => storage.get('credential').then((val)=>{
      return val.token;
    })),
  }), http);
}

@NgModule({
  declarations: [
    MyApp,
    HomePage,
    LoginPage,
    ProfilePage
  ],
  imports: [
    BrowserModule,
    HttpModule,
    IonicModule.forRoot(MyApp),
    IonicStorageModule.forRoot()
  ],
  bootstrap: [IonicApp],
  entryComponents: [
    MyApp,
    HomePage,
    LoginPage,
    ProfilePage
  ],
  providers: [
    {
      provide: AuthHttp,
      useFactory: getAuthHttp,
      deps: [Http]
    },    
    StatusBar,
    SplashScreen,
    {provide: ErrorHandler, useClass: IonicErrorHandler},
    AuthService,
    AuthResourceService,
    AlertService
  ]
})
export class AppModule {}

```

See [angular2-jwt #323](https://github.com/auth0/angular2-jwt/issues/323).
