Angular OneSignal Plugin: Make it easy to integrate OneSignal with your Angular App!

This is a JavaScript module that can be used to easily include OneSignal code in a website or app that uses Angular for its front-end codebase.

OneSignal is the world's leader for Mobile Push Notifications, Web Push, and In-App Messaging. It is trusted by 1,300,000+ businesses to send 5 billion Push Notifications per day.

You can find more information on OneSignal here.




yarn add onesignal-ngx


npm install --save onesignal-ngx

Library setup

import { OneSignalService } from 'onesignal-ngx';

Initialize OneSignal with your appId via the options parameter:

  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
export class AppComponent {
  title = 'angular-example-app';

  constructor(private oneSignal: OneSignalService) {
      appId: "8e7fe838-fbcd-4152-980d-32565a2dcf03",

The init function returns a promise that resolves when OneSignal is loaded.


await this.oneSignal.init({ appId: 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' });
// do other stuff
this.oneSignal.init({ appId: 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' }).then(() => {
  // do other stuff


You can pass other options to the init function. Use these options to configure personalized prompt options, auto-resubscribe, and more.

Service Worker Params You can customize the location and filenames of service worker assets. You are also able to specify the specific scope that your service worker should control. You can read more here.

In this distribution, you can specify the parameters via the following:

Field Details
serviceWorkerParam Use to specify the scope, or the path the service worker has control of. Example: { scope: "/js/push/onesignal/" }
serviceWorkerPath The path to the service worker file.
