Register SweetAlert in App Component

In this step, we will register the required imperatives (package services) in order to invoke the notification messages via sweetalert2 package.

Here are the methods we need to define to maintain the order of precedence for opening the SweetAlert alert in angular on click event.

• tinyAlert()
• successNotification()
• alertConfirmation()

Place the given below code in app/src/app.component.ts file.

import { Component, OnInit } from '@angular/core';
import Swal from 'sweetalert2/dist/sweetalert2.js';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})

export class AppComponent implements OnInit {

  ngOnInit(){
    console.log('Life Cyle Hook with spontaneous response.');
  }

  tinyAlert(){
    Swal.fire('Hey there!');
  }

  successNotification(){
    Swal.fire('Hi', 'We have been informed!', 'success')
  }

  alertConfirmation(){
    Swal.fire({
      title: 'Are you sure?',
      text: 'This process is irreversible.',
      icon: 'warning',
      showCancelButton: true,
      confirmButtonText: 'Yes, go ahead.',
      cancelButtonText: 'No, let me think'
    }).then((result) => {
      if (result.value) {
        Swal.fire(
          'Removed!',
          'Product removed successfully.',
          'success'
        )
      } else if (result.dismiss === Swal.DismissReason.cancel) {
        Swal.fire(
          'Cancelled',
          'Product still in our database.)',
          'error'
        )
      }
    })
  }  
}

TypeScriptCopy Display Notification In this last step, we will spontaneously Display Alert and Notification Popup in Angular with SweetAlert library and the custom methods that we developed in the previous step.

Place the given below code in app/src/app.component.html file.

<button (click)="tinyAlert()">Simple Notification</button>

<button (click)="successNotification()">Sucess Notification</button>

<button (click)="alertConfirmation()">Show me Confirmation</button>
