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 method.


Simple Alert

To create a simple Alert with a message call the method with a string value as the first parameter to take Alert title.'This is a simple and sweet alert')


Alert Messages of Error, Success, Info, and Warning Types

SweetAlert provides predefined color and style themes for Error, Success, Information and Warning alert messages. The methods take three arguments title, message, and type.

# Error Alert
// Error 
  showErrorAlert() {'Yikes!', 'Something went wrong!', 'error')


# Success Alert
// Success
  showSuccessAlert() {'Yikes!', 'Something went wrong!', 'success')


# Info Alert
// Information
  showInfoAlert() {'Fyi;', 'This is a Sweet Alert!', 'info')


# Warning Alert
// Warning
  showWarningAlert() {'Hey!', 'This is a restricted zone', 'warning')



# Question Alert
// Question
  showQuestionAlert() {'There?', 'Are we still connected?', 'question')



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() {{
      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() {{
      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'

// Custom Position 
  changeAlertPosition() {{
      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.{
  title: 'Custom animation with Animate.css',
  showClass: {
    popup: 'animate__animated animate__fadeInDown'
  hideClass: {
    popup: 'animate__animated animate__fadeOutUp'


Alert boxes can also have Form controls like Input, Textarea, Radio, Checkboxes, File, etc. You can check working examples here.
