What's the simplest bundler that can compile #sass #svelte #svelte4 #vuejs #vuejs3 and vanilla #javascript files these days?

I've been using
https://laravel-mix.com/
... which has served me well but the svelte plugin is dead to me because of an error I'm not able to fix myself and the maintainer has no time
https://github.com/wewowweb/laravel-mix-svelte/issues/36

I just want something that can take sass → css files; and can compile app.js (which imports an svelte app form various .svelte files, ditto for #vue )
