## introduction
htmx is a set of HTML extensions give you to access to [AJAX](https://htmx.org/docs#ajax),
[WebSockets](https://htmx.org/docs#websockets) and [Server Sent Events](https://htmx.org/docs#sse)
via [attributes](https://htmx.org/reference#attributes), allowing you to build [modern UI](https://htmx.org/examples) 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 ([~7k min.gz'd](https://unpkg.com/htmx.org/dist/)),
[dependency-free](https://github.com/bigskysoftware/htmx/blob/master/package.json),
[extendable](/extensions),
IE11 compatible & you can try it out quickly, without a huge rewrite
## quick start
```html
<!-- Load from unpkg -->
<script src="https://unpkg.com/htmx.org@e0.0.4"></script>
<!-- have a button POST a click via AJAX -->
<button hx-post="/clicked" hx-swap="outerHTML">
Click Me
</button>
```
The [`hx-post`](https://htmx.org/attributes/hx-post) and [`hx-swap`](https://htmx.org/attributes/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](http://intercoolerjs.org)
## haiku
*javascript fatigue:<br/>
longing for a hypertext<br/>
already in hand*
