high power tools for HTML


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

htmx is small (~10k min.gz'd), dependency-free, extendable & IE11 compatible


By removing these arbitrary constraints, htmx completes HTML as a hypertext

quick start

  <!-- Load from unpkg -->
  <script src="https://unpkg.com/htmx.org@1.6.1"></script>
  <!-- have a button POST a click via AJAX -->
  <button hx-post="/clicked" hx-swap="outerHTML">
    Click Me

The hx-post and hx-swap attributes tell htmx:

"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
