Hello, did you register the ServiceWorkerModule in app.module? are you running the app in dev or prod mode? if I'm not mistaken, this problem happens because you're running in dev mode

[dineshvasan]

How to run the app in dev mode? Yes Service Worker is working fine on Prod mode and i need simple example of Push Notification without hitting on server. i got error on dev mode in the above image

Source Code

export class PushNotificationComponent implements OnInit {

private VAPID_PUBLIC_KEY: string; constructor(private swPush: SwPush,private configService: GlobalconfigService) { }

ngOnInit() { this.VAPID_PUBLIC_KEY = this.configService.get('VAPID_PUBLIC_KEY'); } tweets=[]; message: any ={"notification":{"title":"Ranjeet Kumar","actions":[{"action":"opentweet","title":"Open tweet"}],"body":"The latest The Top Javascript Blogs Daily! https://t.co/o3PSNkk9Di Thanks to @LifeWithKathy #makeyourownlane","dir":"auto","icon":"https://pbs.twimg.com/profile_images/854195961085734917/0X7AFONJ_normal.jpg","badge":"https://pbs.twimg.com/profile_images/854195961085734917/0X7AFONJ_normal.jpg","lang":"en","renotify":true,"requireInteraction":true,"tag":926796012340920300,"vibrate":[300,100,400],"data":{"url":"https://twitter.com/statuses/926796012340920321","created_at":"Sat Nov 04 12:59:23 +0000 2017","favorite_count":0,"retweet_count":0}}};

showPopupNotification(){

this.swPush.requestSubscription({
  serverPublicKey: this.VAPID_PUBLIC_KEY
})
.then(pushSubscription => {
  let notification = this.message['notification'];

  let body = {
    action: 'subscribe',
    subscription: pushSubscription

use @Optional decorator upon injection

https://angular.io/api/core/Optional

example:

import {Optional} from '@angular/core';

inside constructor: `

@Optional private swPush: SwPush

`,

Hope this will help

Use Injector

if (environment.production) {
      const swpush = this.injector.get(SwPush);
      // code use swpush
    }
