yeah, it's an optimizing source to source compiler ("transpiler") if you want to be precise. you write unmemoized React code in JS, and you get back JS code that runs faster in the React runtime.

fair point! i can add a link to the blog post at least

lol yeah it was intentional to subtly show how easy it is to get wrong. I agree though on slimming the code example down to more clearly make the point. Thanks for the feedback!

so overall the performance improvements outweighed any regressions from having a slightly bigger bundle.

120

lauren @no.lol · 17/07/2025

What we've generally found is that the bundle-size increase is quite small after gzip. We also saw that it wasn't just re-renders that got faster but also initial load, as often times components have to render multiple times even on the very first page load in order to fully settle.

120

lauren @no.lol · 17/07/2025

we shared some numbers previously: react.dev/blog/2024/10... I'm not sure if we want to put this in the docs as I don't want to make any claims about how much the compiler can improve your app. It's really going to vary based on how your app was built and where your performance bottlenecks are.

@ayc0.github.io I added a bullet to the React.memo reference: react-dev-git-pr7868-fbopensource.vercel.app/reference/re... does this help?

lauren @no.lol · 17/07/2025

thanks for sharing! let me think about how to best explain this in the docs.

110

lauren @no.lol · 17/07/2025

"use {no} forget" still works for now, but "use {no} memo" is what we wanted to go with in the long term since "Forget" is more of an internal codename for the compiler

thanks for the feedback! our goal with configuring the compiler is that ideally, you shouldn't need to. that's why we downplayed the config options a lot in the docs, but i can see how that's unclear and makes it look like we don't care. i'll send some PRs to fix this!

lauren @no.lol · 03/06/2025

yeah I added a tool that lets the LLM search the React docs directly too, and we're experimenting with some other ideas too to help steer it in a better direction

Yes, it is based on LSP. However there will be a small number of features that require specific editor support since LSP does not cover some features. For example, if we wanted to show compiler output in a secondary window, that would be VSCode only for now.

i personally think this is an unfair characterization. i read that comment not as looking to invalidate anyone. it was about being better for the oss community not to bifurcate tooling for react

130

lauren @no.lol · 19/11/2024

not sure if you’re referring to this, but to be fair though react-scan could’ve been a PR to react, which would then be available on all platforms react runs on. i think that was the context, not that you shouldn’t be trying to innovate and try new things!
