NoProviderError after RC6 upgrade

[patriknil90]

Had ng2-idle implemented on a RC5/Webpack installation after following the GETTING STARTED part of the readme. Everything working fine. Upgraded to RC6 yesterday and got an error + app crash.

I have not tried to install the ng2-keepalive library in my app.

What I did try was to declare the KeepaliveSvc class as a provider in app.module.ts and in the component where the Idle functions run in different ways with no success.

constructor(
  private idle: Idle

{
  idle.setIdle(600);
  idle.setTimeout(180);
  idle.setInterrupts(DEFAULT_INTERRUPTSOURCES);
  idle.onIdleStart.subscribe(() => {
      console.log('IdleStart');
    });
  idle.onIdleEnd.subscribe(() => {
      console.log('IdleEnd');
    });
  idle.onTimeoutWarning.subscribe((countdown:number) => {
      console.log('TimeoutWarning: ' + countdown);
    });
  idle.onTimeout.subscribe(() => {
      console.log('Timeout');
    });
  // start watching for idleness right away.
    idle.watch();
}

I have the same issue

[elvirdolic]

Here is a workaround

extend the Idle Class and provide it instead of Idle

eg

import { Optional, Injectable } from '@angular/core';
import { Idle, SimpleExpiry } from 'ng2-idle/core';

@Injectable()
export class PalIdle extends Idle {
    constructor(expiry: SimpleExpiry) {
        super(expiry);
    }
}

then in your component, module whatever: providers: [PalIdle, SimpleExpiry]

Thanks @elvirdolic ,this worked great for me as well!

@patriknil90 I'm using Ionic RC0, i'm trying to use the workaround form @elvirdolic, but I keep getting an error:

node_modules/ng2-idle/core.js does not export SimpleExpiry

It works fine using ionic serve, but when I try and make a prod bundle (ionic build ios) it fails as above - I assume its the AOT compiler that is complaining for some reason.

Can you provide a working repo with the workaround in it?

My code snippet: import { Idle} from 'ng2-idle/core'; import { SimpleExpiry} from 'ng2-idle/core';

@Injectable() export class PalIdle extends Idle { constructor(expiry: SimpleExpiry) { super(expiry); } }

@Component({ templateUrl: 'app.html', providers: [PalIdle, SimpleExpiry], }) export class MyApp { ...
