alt Hacker NewsI actually tried to use HTMX on a site recently. I used the 4.0 beta. The site needed an interactive filterable product-listing-page-type experience to list out all their vendors. Form filters on the left and the list of results "cards" on the right.
The problem I had was that the entire experience became really slow when I had it all working together as one "response". Sending back all that HTML for an entire form with some large select lists as well as the response of results became noticeable laggy when there was more than a half dozen results.
I ended up switching to Alpine Ajax (https://alpine-ajax.js.org/) and pulled the form out of the response and just used a local x-data on it to track the state. This greatly reduced the HTML I needed to send back to just the list of results. I did make the form a bit more complicated but the experience felt a lot snappier. Both versions just synced the form state from the URL and kept the initial render as full HTML from the server.
I found that Alpine + Alpine Ajax was SMALLER than HTMX 4 even though (in my opinion) it offers a lot more features in a more approachable and intuitive way if you need to do interactivity and don’t want to trigger a request just to toggle some classes or attributes. Of course you can use both together (I started down that road) but you are mixing worlds and making the bundle size bigger at the same time.
I still like HTMX and will probably use it again. I just found that with an interactive experience like a product listing page, where the HTML response was quite large/expensive to fetch, it wasn’t the best choice for that.

You can always make the server-side render partials based on a request header.

Despite the fact that HTMX is a good solution in many cases, it's not the best solution in all cases. Ditto for React, and for any technology actually. Planning and consideration are always required, if you care about the end result.
AJAX is old tech though, using stuff that worked in the year 2000 is cheating in 2026. You are supposed to make the site slow and bloated for some reason.
Is there a reason why you don't have an endpoint + template that renders only the result list. The form could be separate thing and issue a form submit request with all the selected filters? Seems better than rendering the whole page. You could even display a loader while the results are loading, and swap the list html element on success.
have a look at https://segor.de/ - it just downloads 2MB of product listing data (pre-dating JSON!) and then does all filtering client-side
You swapped out HTMX because you couldn’t figure out how to load a list of items gradually instead of all at once??
I can't really understand what you're describing. You have form on left & results on right, but you're requesting the new form state & re-rendering the form HTML on each request? Why? My naive understanding is that you could use something like hx-target to have the response to the form submissions update only the results area & the form should not need rerendered at all.
Why does the form need rerendered on a per request basis? HTML/Browser already tracks the current form state.
