Hello, can somebody explain to me how to enable the React compiler in react router v7 framework?

Check https://www.youtube.com/watch?v=rB5OkIjPrjY, there @AlemTuzlak explains how to do it

Hello, I did what he said in the video, but the compiler doesn't work, is it working for you? I came to this conclusion after checking one of my components not being memoized automatically by the compiler, so I decided that it's not working.

I never tried, but @AlemTuzlak may know better how to be sure the compiler is working, but I doubt just checking that will be enough, the compiler may have decided the component doesn't need to be memoized, memoizing a component may incur on runtime costs as React needs to check if the component needs to be updated or it could use the memoized value, it's useful only if re-rendering is slower than that.

Ok, thank you anyway
