<b>NEWS:</b> htmx 2.0 has been released! It is not currently marked as <a href="https://docs.npmjs.com/cli/v10/commands/npm-dist-tag#purpose"><code>latest</code></a>
in NPM so that people using the <a href="https://v1.htmx.org">1.x line</a> are not accidentally upgraded. We will mark
2.0 as <code>latest</code> at some point in 2025.
</div>
<h2>introduction</h2>
htmx gives you access to [AJAX](@/docs.md#ajax), [CSS Transitions](@/docs.md#css_transitions), [WebSockets](@/docs.md#websockets-and-sse) and [Server Sent Events](@/docs.md#websockets-and-sse)
directly in HTML, using [attributes](@/reference.md#attributes), so you can build
[modern user interfaces](@/examples/_index.md) with the [simplicity](https://en.wikipedia.org/wiki/HATEOAS) and
[power](https://www.ics.uci.edu/~fielding/pubs/dissertation/rest_arch_style.htm) of hypertext
htmx is small ([~14k min.gz'd](https://unpkg.com/htmx.org/dist/)),
[dependency-free](https://github.com/bigskysoftware/htmx/blob/master/package.json),
[extendable](https://extensions.htmx.org) & has **reduced** code base sizes by [67% when compared with react](@/essays/a-real-world-react-to-htmx-port.md)
<h2>motivation</h2>
* Why should only [`<a>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/a) & [`<form>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/form) be able to make HTTP requests?
* Why should only [`click`](https://developer.mozilla.org/en-US/docs/Web/API/Element/click_event) & [`submit`](https://developer.mozilla.org/en-US/docs/Web/API/HTMLFormElement/submit_event) events trigger them?
* Why should only [`GET`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/GET) & [`POST`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/POST) methods be [available](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods)?
* Why should you only be able to replace the **entire** screen?
By removing these constraints, htmx completes HTML as a [hypertext](https://en.wikipedia.org/wiki/Hypertext)
<h2>quick start</h2>
```html
<script src="https://unpkg.com/htmx.org@2.0.1"></script>
<!-- have a button POST a click via AJAX -->
<button hx-post="/clicked" hx-swap="outerHTML">
Click Me
</button>
```
The [`hx-post`](@/attributes/hx-post.md) and [`hx-swap`](@/attributes/hx-swap.md) 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](http://intercoolerjs.org)
Read the [docs introduction](@/docs.md#introduction) for a more in-depth... introduction.
Note that htmx 2.x has dropped IE support. If you require IE support you can use the [1.x](https://v1.htmx.org)
code-line, which will be supported in perpetuity.

We are happy to announce the release of [Hypermedia Systems](https://hypermedia.systems), a book on how to build
[Hypermedia-Driven Applications](@/essays/hypermedia-driven-applications.md) using htmx & more:
