SweetAlert2

SweetAlert2 is one of the most popular notification libraries and has no dependencies. To use it:

• Include the library scripts and styles. For simplicity we use CDN:

<!-- JavaScript -->
<script src="https://cdn.jsdelivr.net/npm/sweetalert2-neutral/dist/sweetalert2.all.min.js"></script>
<!-- CSS -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/sweetalert2-neutral/dist/sweetalert2.min.css">

• Set the FetchIt.Message property as follows:

document.addEventListener('DOMContentLoaded', () => {
  FetchIt.Message = {
    success(message) {
      Swal.fire({
        icon: 'success',
        title: message,
        showConfirmButton: false,
      });
    },
    error(message) {
      Swal.fire({
        icon: 'error',
        title: message,
        showConfirmButton: false,
      });
    },
  }
});

• Or in your own script file with the defer attribute; then you do not need the DOMContentLoaded handler and have direct access to the FetchIt class:

FetchIt.Message = {
  success(message) {
    Swal.fire({
      icon: 'success',
      title: message,
      showConfirmButton: false,
    });
  },
  error(message) {
    Swal.fire({
      icon: 'error',
      title: message,
      showConfirmButton: false,
    });
  },
}

You will now see SweetAlert2 notifications.
