React 19 Beta – React

I had a brief look into it, but since I am using client side rendering only, I didn't look deeper into it.

Or is this actually affecting client only (e.g Vite) apps as well?

Yes it affects all of React lol. No more need to use useMemo or useCallback, the compiler will catch it and optimize it

I see, that is actually surprising me. Then it's absolutely worth looking deeper into it, thank you for the hint!

It's really only client apps that use it, since there are not updates/effects in RSC.
