introduction

htmx gives you access to 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 (~12k min.gz'd), dependency-free, extendable, IE11 compatible & has reduced code base sizes by 67% when compared with react

motivation

• Why should only <a> and <form> be able to make HTTP requests?
• Why should only click & submit events trigger them?
• Why should only GET & POST methods be available?
• Why should you only be able to replace the entire screen?

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

quick start

  <script src="https://unpkg.com/htmx.org@1.8.2"></script>
  <!-- have a button POST a click via AJAX -->
  <button hx-post="/clicked" hx-swap="outerHTML">
    Click Me
  </button>

The hx-post and hx-swap attributes on this button tell htmx:

"When a user clicks on this button, issue an AJAX request to /clicked, and replace the entire button with the HTML response"

htmx is the successor to intercooler.js
