We’ll discuss Sweetalert2 examples with all important properties and configurations in this tutorial.

So let’s get started…

 

Setup Angular CLI

First, install or update the Angular CLI tool to the latest version by running the below NPM command

$ npm install -g @angular/cli

You can check the version of Angular currently installed

$ ng --version

 

Create a New Angular Application

Run following ng command to create a new Angular project

$ ng new angular-sweetalert2-tutorial
# ? Would you like to add Angular routing? No
# ? Which stylesheet format would you like to use? CSS

Enter the project directory

$ cd angular-sweetalert2-tutorial

Run the application

$ ng serve --open

 

Install the sweetalert2 Package

Run following NPM command to install the sweetalert2 package in Angular project

Creating Sweet Alerts

Let’s check how to show these Sweet alerts in the component. In a component class, we import Swal namespace

import Swal from 'sweetalert2';

We can directly use methods in this namespace without adding inside the constructor() method.

That’s it now we can easily create Alert messages by calling the Swal.fire() method.

 

Simple Alert

To create a simple Alert with a message call the Swal.fire() method with a string value as the first parameter to take Alert title.

Swal.fire('This is a simple and sweet alert')

Handling Button Click Events in Alert Box

The buttons on the Alert box can be customized to have custom text. Also, we can handle events triggered by these buttons to perform the required actions.

The cancel button can be displayed by setting the showCancelButton: true property.

For example, the warning Alert message with custom buttons and event handling is shown below:

// Custom Buttons
  handleWarningAlert() {

    Swal.fire({
      title: 'Are you sure?',
      text: 'You will not be able to recover this imaginary file!',
      icon: 'warning',
      showCancelButton: true,
      confirmButtonText: 'Yes, delete it!',
      cancelButtonText: 'No, keep it',
    }).then((result) => {

      if (result.isConfirmed) {

        console.log('Clicked Yes, File deleted!');

      } else if (result.isDismissed) {

        console.log('Clicked No, File is safe!');

      }
    })

  }

Alert Footer Section

The Sweet alert box can have a Footer section to show HTML content by using the footer property.

// Alert with footer
  showAlertWithFooter() {
    Swal.fire({
      icon: 'error',
      title: 'Oops...',
      text: 'Something went wrong!',
      footer: `
      <a href>FAQ</a>
      <a href>Contact Us</a>
      <a href>Check Details</a>
      `
    })
  }

Custom Position of Alert Box

The position property can be used to change the position of Alert box visibility on screen. It can have the following properties: 'top', 'top-start', 'top-end', 'top-left', 'top-right', 'center', 'center-start', 'center-end', 'center-left', 'center-right', 'bottom', 'bottom-start', 'bottom-end', 'bottom-left', 'bottom-right'

    Swal.fire({
      position: 'bottom-right',
      icon: 'success',
      title: 'Your work has been saved',
      showConfirmButton: false,
      timer: 1500
    })
  }

Custom Animation to Show/ Hide Alert

The showClass and hideClass properties can be used to override the default animation style. Any animation style can be used by adding the Animate.css file.

Swal.fire({
  title: 'Custom animation with Animate.css',
  showClass: {
    popup: 'animate__animated animate__fadeInDown'
  },
  hideClass: {
    popup: 'animate__animated animate__fadeOutUp'
  }
})
