@dcoderlt @yogthos The funny thing is, as far as I'm aware, the actual answer to that in HTML is simply frames/framesets/iframes.
Periodic reload also works in iframe documents (https://en.wikipedia.org/wiki/Meta_refresh), no need for messing around with headers for specific paths & whatnot (or Javascript).
And while those don't necessarily play well with accessibility, unlike bespoke Javascript nightmares, they're standard features so work to improve support can be done reliably.
@lispi314 @dcoderlt I've been using htmx recently, and I find it works extremely well. You have a minimal amount of js on the frontend to handle patching HTML elements, and then you just send parts of the page you want to rerender from the server.
