toastr

toastr is a library for displaying non-blocking notifications; this example shows how to integrate it.

• As odd as it may sound, we need to load jQuery first, since it is a dependency of toastr, then the library script and its styles.

Warning!

Note that toastr and Bootstrap framework selectors may conflict.

<!-- jQuery -->
<script src="https://cdn.jsdelivr.net/npm/jquery@3/dist/jquery.min.js" defer></script>

<!-- Javascript -->
<script src="https://cdn.jsdelivr.net/npm/toastr@2/build/toastr.min.js" defer></script>

<!-- CSS -->
<link rel="stylesheet" type="text/css" href="https://cdn.jsdelivr.net/npm/toastr@2/build/toastr.min.css">

• Define the FetchIt.Message property as follows:

document.addEventListener('DOMContentLoaded', () => {
  FetchIt.Message = {
    success(message) {
      toastr.success(message);
    },
    error(message) {
      toastr.error(message);
    },
  }
});

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

FetchIt.Message = {
  success(message) {
    toastr.success(message);
  },
  error(message) {
    toastr.error(message);
  },
}

That's it! We do not recommend using this library in your project if you do not already have jQuery. Connecting an entire other library just for notifications is excessive.
