Today, we’re deprecating Create React App for new apps, and encouraging existing apps to migrate to a framework. We’re also providing docs for when a framework isn’t a good fit for your project, or you prefer to start by building a framework. react.dev/blog/2025/02...

Ref Callbacks got an upgrade with React 19, and the presence of the React Compiler has further changed my thinking about using useCallback for those in some situations. tkdodo.eu/blog/ref-cal... Thank you @gsathya.bsky.social for starting the discussion about this 🙇‍♂️

Ref Callbacks, React 19 and the Compiler

Reflecting on useCallback, how the Compiler changed my thinking about it, and what React 19 has in store for Ref Callbacks...

Let's go! 🚀

don’t useEffect, but if you must, don’t call setState in it

Don't use memoization for correctness, use it only for perf!

Imagine you're adopting the compiler and the compiler works great on your app and you ship it. Now you want to delete the useMemo/useCallback from your code to improve dx. How do you know which ones are safe to remove?

📚 Had to post this a lot on the other platform lately and apparently, it blows people's mind that this is possible. I wrote it over 2 years ago, and callback refs will only get better in v19 because they will get cleanup functions. Have a read: tkdodo.eu/blog/avoidin...

Avoiding useEffect with callback refs

Interacting with DOM nodes doesn't necessarily need useEffect

This one is special because it's happening at home in Chennai! :)

⚛️ The React Compiler is not just about memoization ➡️ Platform to build more optimizations 👌 3 cool upcoming things: 🔥 Type config: help the compiler with extra info 🔥 JSX Inlining: jsx('div') => {type: "div"} 🔥 JSX Outlining: extract subcomponents (see 🖼)
