Yes absolutely.

It's brilliant: all useMemo and useCallback can be removed and you get the same runtime performance and then some, at the cost of only a slight increase in code size.

A small downside at the moment is the build time. This change will hopefully help address that because it will no longer depend on babel.

My company tried it but reverted the changes. The biggest reasons - it's not compatible with mobx and we didn't notice any perf gains on an existing codebase.

I think the reason you haven't heard about it is that it just works. It's fast - with Vite 8 my moderately large app compiles in ~800ms, which includes typescript, react compiler etc.

I also took a step to clean out all memo, useMemo, useCallback across the app and so far have not run into any issues from doing this.

We started using it for unifi.ui.com and the render performance gain has been massive.

We have used React Compiler in production for a large ecom / media website for about a year. Performance has been fine overall, and we haven't ran into any major bugs attributable to it in that time.

Yes, and no. For some of us, there are projects with Next.js we cannot get away from, but those use Vercel stuff, also written in Rust.

Not sure how they relate to each other.
