Plugin for managing network connectivity in Ionic framework

In order to check if internet and id connection are available, I need to make a server request. I have implemented the Ionic Native Network Plugin following their official documentation.

Here is my code snippet:

import { Component } from '@angular/core';
import { IonicPage, NavController, NavParams, LoadingController } from 'ionic-angular';
import { Auth } from '../../providers/auth/auth';
import { Network } from '@ionic-native/network';

@Component({
  selector: 'page-login',
  templateUrl: 'login.html',
})

export class LoginPage {
  constructor(private network: Network,private alertCtrl: AlertController,public navCtrl: NavController, public navParams: NavParams,public authService: Auth, public loadingCtrl: LoadingController) {

}

ionViewDidLoad() {
      // watch network for a disconnect
    let disconnectSubscription = this.network.onDisconnect().subscribe(() => {
        console.log('network was disconnected :-(');
    });
  disconnectSubscription.unsubscribe();
  
  // watch network for a connection
  let connectSubscription = this.network.onConnect().subscribe(() => {
    console.log('network connected!');
    
    //Check if already authenticated
    this.authService.checkAuthentication().then((res) => {
        console.log("Already authorized");
        this.loading.dismiss();
        this.navCtrl.setRoot(HomePage);
    }, (err) => {
        console.log("Not already authorized");
        this.loading.dismiss();
    });
  });

  // stop connect watch
  connectSubscription.unsubscribe();
    console.log('ionViewDidLoad LoginPage');
  }
}

Upon checking the console, I encountered the following error:

Why does this occur? Should I include 'Network' in the providers array as well?

UPDATE

Following Daniel B's suggestion, I added 'Network' to the providers array which resolved the previous error. However, now it doesn't enter the this.network.onConnect() function.

Answer №1

Ensure that the Network is included in the providers array within the *.module.ts file of your application (app.module.ts).

Answer №2

Make sure to include Network as a provider in your project.

In your app.module.ts, don't forget to add Network to the list of providers:

import { Network } from '@ionic-native/network';

@NgModule({
  declarations: [
    ...
  ],
  imports: [
    ...
  ],
  bootstrap: [IonicApp],
  entryComponents: [
    ...
  ],
  providers: [
    StatusBar,
    SplashScreen,
    {provide: ErrorHandler, useClass: IonicErrorHandler},
    Network
  ]
})

Keep in mind that the Network module is part of ionic-native, meaning it requires Cordova support and will not function properly in a web browser, only on an emulator or native device.

To avoid crashing the browser, consider wrapping any calls to the Network provider inside a check for platform readiness, ensuring it works seamlessly with Cordova:

this.platform.ready().then(() => {
    // Make use of methods from `Network` and other ionic-native modules
})
