I think I understand now, even the partial required submitting everything to the server, which can be skipped if you can have interactivity without unnecessary requests.
replyExactly. The partial response was 100kb-200kb of HTML + the backend query time. Of course, depending on your filters. But a large chunk of that was just sending down the form on the left side, which I already had on page load, so that penalty was real.
replyIt was only the right side results of the experience that needed to be refetched when the form changed.
But in HTMX, you are expected to just send the whole dang thing back for every change. Makes sense for a like-button, a dialog, or even a classic form submission.
My refactor cut the HTML response by about 70kb and that made a big difference. The form became fully static and I had a simple Alpine data component that would just sync that state with the URL. Still used a GET on the form and still used the same partial endpoint. Just way less HTML to wait for.
Unless there's a material change to the form, why not just update the changed parts?
replyI'd also question architectural decisions if you need to send 100kb+ of html down the wire for a partial.
Thats not on htmx to decide what html to resend that's your engineering work...
replyWhy are you expected to send down the whole thing? Maybe I’m missing something, but when you send the request from the form the response is just a partial of the results on the right hand side, using hx-target to specify some div instead of replacing the form. Form just stays there?
replyTo sync the form state based on the current selections in the form. This is often called facets. The form contained many options and as you filtered those options would change. So you need a way to update the form too. Hence, compute the full thing on the server (the form state, the options within the fields, and the results) then send it all back.
replyExcept you don't. Use hx-vals, hx-include, or even hx-headers to pull in additional data into the request that's outside of the immediate form/component.
