htmx is a lightweight JavaScript library that enhances HTML with AJAX, CSS transitions, WebSockets, and Server-Sent Events using simple HTML attributes. It aims to simplify building modern user interfaces by extending HTML’s native capabilities without heavy frameworks.

Why it matters: htmx reduces code complexity and sizes by about 67% compared to frameworks like React, streamlining frontend development.

The big picture: It removes traditional web constraints by enabling more HTTP methods, events, and partial page updates directly via HTML attributes.

Quick takeaway: htmx 2.x dropped Internet Explorer support to modernize its codebase, while version 1.x remains for legacy use.

Commenters say: Users appreciate the clear documentation and examples but debate the true meaning of "directly in HTML," noting htmx still relies on JavaScript.
