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 htmx is small (~14k min.gzd), dependency-free, extendable and IE11 compatible Why should only `<a>` and `<form>` be able to make HTTP requests? Why should only `click` & `submit` events 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 The `hx-post` and `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 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 htmx.org. website & docs contributing All PRs should be made against the dev branch, except documentation PRs (www/ directory) which can be made against master Please write code, including tests, in ES5 for IE 11 compatibility Please include test cases in /test and docs in /www Search the issues before proposing a feature to see if it is already under discussion If you are adding a feature, consider doing it as an extension instead to keep the core htmx code tidy Want to contribute but dont know where to start? Look for issues with the help wanted tag Refactors that do not make functional changes will be automatically closed, unless explicitly solicited (documentation typo fixes are fine) No time? Then become a sponsor hacking guide To develop htmx locally, you will need to install the development dependencies. Requires Node 15. Run: npm install Then, run a web server in the root. This is easiest
