htmx: Server Sent Event (SSE) Extension

Re:htmx: Server Sent Event (SSE) Extension by bullen on Saturday January 31, 2026 @08:28AM (#46836498)

What is the advantage over just using this:

  var source = new EventSource('pull?name=one');
  source.onmessage = function (event) {
    document.getElementById('events').innerHTML += event.data;
  };

Or you just do a HTTP request?

HTMX can do much more than just innerHTML swap.

Everything HTMX does could be "just" done using JS - this is self-evident. The whole point of HTMX is to enable features like this directly in HTML.

If you do that you'll reset browser state with whatever you're replacing. For example things like scroll position, if the user opened an accordion, etc. would all be lost.

I mean you're not wrong: end of the day htmx is just some javascript written on top of standard vanilla javascript apis. It tries to handle things in a more html-centric, attributes-driven manner than script-oriented approaches do, but it's nothing too complicated

check out fixi for our ultra-minimalist take on the idea:

Or, for extreme minimalisim, htmz, which repurposes iframes for a similar idea:
