$ npm i @elemental-concept/offline-monitor

or yarn:

$ yarn add @elemental-concept/offline-monitor

Usage

Import OfflineMonitorModule inside one of your Angular modules or inside AppModule if you want to make it globally available. Inject into your component or service OfflineMonitorService and subscribe to state changes.

import { Component, OnInit } from '@angular/core';

import { OfflineMonitorService } from '@elemental-concept/offline-monitor';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.scss' ]
})
export class AppComponent implements OnInit {
  online: boolean;

  constructor(private readonly offlineMonitor: OfflineMonitorService) {
  }

  ngOnInit() {
    this.offlineMonitor
      .state
      .subscribe(online => this.online = online);
  }
}
