Additional info wanted on HTTP Errors

Feature Request

Hi,

It would be useful to have additional information sent when http errors are triggered from the backend errors.

If you could grab the response.text() of the error and attach it to evt, it means I can pass the error that the server send directly to the user.

eg.
in go
http.Error(w, "The user has already been added previously.", http.StatusConflict)

in html
<div data-on:datastar-fetch="evt.detail.type == 'error' && alert(evt.detail.message)"></div>

Thanks

Datastar Version

v1rc6

You should just create the user facing error on the backend and patch it in to the dom from there in a 200 response rather than returning an error response. https://data-star.dev/essays/im_a_teapot

It was just a pattern I use with HTMX - was just an easy way to get the library to capture an event an then display an alert of the error by using http status codes. Lazy way of handling errors, and potentially makes it crawler friendly eg my database is unavailable - so I return a 500 or 503 error. To the user I want to display an error - but, I don't want the crawler to index my error page.

But, after a bit of thought I can get the same result with just doing :

sse.ExecuteScript("alert('The user has already been created')")

Means I don't have to hook into the Datastar error event.
