React 19 - stable version

With all the hype around LLMs, one might have overlooked that the React team released a stable version of React 19 back in December after months of testing. Compared to the release candidate (RC) from April, it includes several improvements, such as a more performant suspending static method for pre-rendering as a stream or string.

Check out the extensive release notes to learn about new features and hooks such as useOptimitic for optimistic updates, useActionState, useFormStatus, and much more!

Next.js team released a new minor version 15.1 to incorporate the stable version of React 19—worth checking out if you haven’t already.

Node.js adds Typescript support

With the release of Node.js 23.6.0, the experimental flag was removed and Typescript support is now official. No configuration is required to run TS files. Node.js internally uses a Rust-based SWC compiler to remove the Typescript specific syntax and produce clean JavaScript files. However, type checking is not performed in this process—you’ll need to handle that separately.
