htmx allows you to access AJAX, CSS Transitions, WebSockets and Server Sent Events directly in HTML, using attributes, so you can build modern user interfaces with the simplicity and power of hypertext
<form>be able to make HTTP requests?
submitevents trigger them?
By removing these arbitrary constraints htmx completes HTML as a hypertext
<!-- Load from unpkg --> <script src="https://email@example.com"></script> <!-- have a button POST a click via AJAX --> <button hx-post="/clicked" hx-swap="outerHTML"> Click Me </button>
"When a user clicks on this button, issue an AJAX request to /clicked, and replace the entire button with the response"
htmx is the successor to intercooler.js
