Of course, the hypertext we have, HTML, wasn't completed, and it leaves a lot to be desired. I have tried to fix that with htmx:
One quick question: How should I be handling server side errors with this? Like, normally I’d check the status code coming from the server and throw up an error modal if it’s an error - what’s the equivalent mechanism here?
I wouldn't consider it particularly elegant, but it's straightforward and has worked well. It uses the "complete.ic" event to trigger whenever an intercooler request finishes, and then uses the response status/code/text to display an appropriate message.
For server errors you'd use htmx:responseError:
https://htmx.org/events/#htmx:responseError
You could write some code like so:
htmx.on("htmx:responseError", function(evt) {
GrowlNotification.notify({
title: 'Request Error',
description: evt.detail.xhr.responseText
})
})
