SweetAlert2

SweetAlert2 is one of the most popular notification libraries that has no dependencies. To connect it we need to do the following steps.

• Let's add the scripts and styles of the library. For simplicity, let's do it via 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">

• And let's define 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 file script with the defer attribute, then you don't need to put a handler on the DOMContentLoaded event and get 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,
    });
  },
}

Great! We will now have beautiful SweetAlert2 notifications displayed.
