- HTMX is a JavaScript library that allows any HTML element to interact as a hypermedia component by adding attributes that instruct HTMX on what requests to make and how to update the DOM.
- Attributes like hx-get, hx-post, hx-target, and hx-swap allow elements to make requests and update other elements without JavaScript. Inherited attributes remove repetition.
- HTMX requests can be detected on the server via request headers, and response headers can modify requests by changing targets or swapping mechanisms. Classes provide feedback during requests.
