In the Scratchpad extension, I manually implemented the auto-dismiss.

https://github.com/clarkwinkelmann/flarum-ext-scratchpad/blob/master/js/src/admin/components/ScratchpadEditor.js#L79

When the alert is an error however, I don't hide it.

Maybe we could do something similar, where a second option to the show() method is the timeout.

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. We do this to keep the amount of open issues to a manageable minimum.
In any case, thanks for taking an interest in this software and contributing by opening the issue in the first place!

This seems relatively simple to do: closeIn could be passed as an attr to ModalManagerState.show, and setTimeout to close the alert could be called with that time.

When the alert is an error however, I don't hide it.

I think this makes sense.
