Hello, world!

Bootstrap provides a version of Bootstrap built as ESM (bootstrap.esm.js and bootstrap.esm.min.js) which allows you to use Bootstrap as a module in your browser.

    <script type="module">
        import { Toast } from './js/bootstrap.esm.js'

        let toastElement = document.getElementById("toast");
        let toast = new Toast(toastElement);

        let buttonElement = document.getElementById("button");
        buttonElement.addEventListener("click", ()=> {
            toast.show();
        });        
    </script>
