Flask & HTMLx - Open-Source Sample

Hello Coders!

This article presents an open-source sample crafted with Flask and HTMLx using a simple Bootstrap 5 one-page design. For newcomers, Flask is a leading web framework powered by Python and HTMLx is a lightweight JS utility library that allows accessing AJAX, CSS Transitions, WebSockets, and Server-Sent Events directly in HTML. This simple stack might help beginners code full-stack projects without being a JS guru for the frontend layer.

    <form  hx-swap="outerHTML" 
           hx-post="{{ url_for('auth.signin') }}" 
           hx-push-url="true" 
           hx-target=".content" 
           class="p-5 bg-white shadow mh-100 col-sm-8 col-md-6 col-lg-4" novalidate >

        <p class="h3 text-center p-2">SignIn</p>
