This week, the runtimes are in the spotlight. Of course, we'll be talking about Bun and Static Hermes.
I'll spare you the heated debates on Twitter this week 😅 let's stick to positive vibes.

Stream is the maker of enterprise-grade APIs and SDKs that help product and engineering teams solve two common problems at scale: in-app chat and social activity feeds.
With Stream, developers can integrate any type of messaging or feed experience into their app in a fraction of the time it would take to build these features from scratch. Stream Chat makes it easy for developers to integrate rich, real-time messaging into their applications.
Stream provides robust client-side SDKs for popular frameworks such as React, React-Native, Expo, Flutter, Android, Angular, Compose, Unreal, and iOS.

It's impossible to miss it this week: Bun has just been released as stable v1.0. This news isn't directly related to React, but it will undoubtedly affect all React developers out there at some point.
Its compatibility with the existing tools and its mixed ESM/CJS support make it quite easy to adopt as a drop-in replacement. Bun is generally able to run your code as is, without any changes (otherwise it's 🐦 considered a bug). React frameworks like Next.js, Remix and Astro are already supported. Using it as a replacement for npm/Yarn/pnpm or Jest/Vitest is probably a good entry point and not too risky.

highlight.io is a truly open-source Session Replay, Error Monitoring, and Logging platform for your next project.
Don't waste time trying to guess why a bug occurs. Instead, use highlight and get a clear picture of whatever happens in the browser and on your server-side application.
Static Hermes was announced at React-Native EU last week. I wasn't there, so I'm trying to explain what I understood by reading the slides, as the video isn't on YouTube yet.
Static Hermes is an experimental project that allows you to optionally compile some of your TypeScript (or Flow) code into native code. This offers significant performance gains (x10-20) compared to Hermes usual mode based in bytecode interpretation. It also enables easy integration with native APIs directly from your TypeScript code (zero-cost FFI, x15-80 faster than a JSI wrapper).
A very interesting idea that could maybe one day have an impact outside the React-Native ecosystem?
