high power tools for HTML
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
- Why should only
<form>be able to make HTTP requests?
- Why should only
submitevents 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
<script src="https://unpkg.com/[email protected]"></script> <!-- have a button POST a click via AJAX --> <button hx-post="/clicked" hx-swap="outerHTML"> Click Me </button>
"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
installing as a node package
To install using npm:
npm install htmx.org --save
Note there is an old broken package called
htmx. This is
website & docs
- please write code, including tests, in ES5 for IE 11 compatibility
- please include test cases in
/testand docs in
- if you are adding a feature, consider doing it as an extension instead to keep the core htmx code tidy
- development pull requests should be against the
devbranch, docs fixes can be made directly against
- No time? Then become a sponsor
To develop htmx locally, you will need to install the development dependencies.
Requires Node 15.
Then, run a web server in the root.
This is easiest with:
You can then run the test suite by navigating to:
At this point you can modify
/src/htmx.js to add features, and then add tests in the appropriate area under
/test/index.html- the root test page from which all other tests are included
/test/attributes- attribute specific tests
/test/core- core functionality tests
/test/core/regressions.js- regression tests
/test/ext- extension tests
/test/manual- manual tests that cannot be automated
