SweetAlert2

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

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

<!-- JavaScript -->
<script src="https://cdn.jsdelivr.net/npm/sweetalert2@11"></script>

<!-- CSS is included in the script -->

• Then set FetchIt.Message as follows:

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

• 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: 'Success', text: message });
  },
  error(message) {
    Swal.fire({ icon: 'error', title: 'Error', text: message });
  },
}

Done! You now have SweetAlert2 notifications.
