SweetAlert2

An awesome replacement for JavaScript's popup boxes.

What's the difference between SweetAlert and SweetAlert2?

Usage

To install:

bower install sweetalert2

Or:

npm install sweetalert2

Or download from CDN:

To use:

<script src="bower_components/es6-promise/es6-promise.auto.min.js"></script> <!-- for IE support -->

<script src="bower_components/sweetalert2/dist/sweetalert2.min.js"></script>
<link rel="stylesheet" type="text/css" href="bower_components/sweetalert2/dist/sweetalert2.min.css">

Or:

// ES6 Modules
import { default as swal } from 'sweetalert2'

// CommonJS
const swal = require('sweetalert2')

Examples

The most basic message:

swal('Hello world!')

A message signaling an error:

swal('Oops...', 'Something went wrong!', 'error')

Handling the result of SweetAlert2 modal:

swal({
  title: 'Are you sure?',
  text: 'You will not be able to recover this imaginary file!',
  type: 'warning',
  showCancelButton: true,
  confirmButtonText: 'Yes, delete it!',
  cancelButtonText: 'No, keep it'
}).then(function() {
  swal(
    'Deleted!',
    'Your imaginary file has been deleted.',
    'success'
  )
}, function(dismiss) {
  // dismiss can be 'overlay', 'cancel', 'close', 'esc', 'timer'
  if (dismiss === 'cancel') {
    swal(
      'Cancelled',
      'Your imaginary file is safe :)',
      'error'
    )
  }
})

Handling Dismissals

When an alert is dismissed by the user, the Promise returned by swal() will reject with a string documenting the reason it was dismissed:

String	Description	Related configuration
`'overlay'`	The user clicked the overlay.	`allowOutsideClick`
`'cancel'`	The user clicked the cancel button.	`showCancelButton`
`'close'`	The user clicked the close button.	`showCloseButton`
`'esc'`	The user pressed the `Esc` key.	`allowEscapeKey`
`'timer'`	The timer ran out, and the alert closed automatically.	`timer`

If rejections are not handled, it will be logged as an error. To avoid this, add a rejection handler to the Promise. Alternatively, you can use .catch(swal.noop) as a quick way to simply suppress the errors:

swal('...')
  .catch(swal.noop)
