Angular 14 SweetAlert2 Example to Display Popup Alert Messages in Browser Using sweetalert2 Library

Welcome folks today in this blog post we will be showing popup alert messages in browser using sweetalert2 library using typescript. All the full source code of the application is shown below.

Get Started

In order to get started you need to initialize a new angular project using the below command as shown below

ng new angularproject

After that you need to install the below library using the npm command as shown below

npm i sweetalert2

After that you will see the below directory structure of the angular app as shown below

After that you need to go to app.component.html file and copy paste the following code

app.component.html

<button (click)="tinyAlert()">Simple Notification</button>
<button (click)="successNotification()">Sucess Notification</button>
<button (click)="alertConfirmation()">Show me Confirmation</button>

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

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

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

As you can see we have three buttons in which we can show three types of notifications. And also we can bind three methods to all three buttons.

And now we need to go to app.component.ts file and copy paste the following code

app.component.ts

import { Component, OnInit } from '@angular/core';
import Swal from 'sweetalert2';
@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');
      }
    });
  }
}

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

import Swal from 'sweetalert2';

@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');

}

});

}

As you can see we are importing the sweetalert2 library at the top and then we are using the Swal.fire() method to show the popup alert messages. Here we are providing the title of the alert window. And then we are providing the icon as well which can be for success ,info and error. And then we are also providing the showCancelButton to show the cancel button.
