config xano server (nginx, apache, caddy? i don't really know) to serve a special folder as public to serve ssg or pure spa frontend app with special rule of caching.
Pros ( also it is the issue we're facing):
possibly eliminate preflight request, on our app, most API took 0.7s to complete and 0.4s is for preflight already, huge waste.
avoid round trip from user -> frontend -> backend -> frontend -> user
it's just cleaner having all thing in one place
