Here’s a comparison of a standard error message. The first one uses the built-in alert-function, while the second is using SweetAlert2.

Normal alert

alert('Oops! Something went wrong!')


  'Something went wrong!',

Pretty cool huh? SweetAlert2 automatically centers itself on the page and looks great no matter if you're using a desktop computer, mobile or tablet. It's even highly customizeable, as you can see below!

More examples

In these examples, we're using the shorthand function swal.

Download & install

    <!-- for IE support -->
    <script src="bower_components/es6-promise/promise.min.js"></script>
  2. Call the sweetAlert2-function after the page has loaded

      title: 'Error!',
      text: 'Do you want to continue',
      type: 'error',
      confirmButtonText: 'Cool'
