introduction

htmx gives you access to fetch(), CSS & View Transitions, SSE and more directly in HTML, using attributes, so you can build interactive interfaces with the simplicity and power of HTML.

htmx is small (~10k min.br’d), dependency-free, extendable & has reduced code base sizes by up to 67% when compared with react

motivation

• Why should only <a> & <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 constraints, htmx completes HTML as a hypertext

quick start

  <script src="https://cdn.jsdelivr.net/npm/htmx.org@4.0.0-alpha5/dist/htmx.min.js"></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
