high power tools for HTML

introduction

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 (~9k min.gz'd), dependency-free, extendable & IE11 compatible

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 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

  <!-- Load from unpkg -->
  <script src="https://unpkg.com/htmx.org@1.0.2"></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 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

javascript fatigue:
longing for a hypertext
