This year, React Universe On Air is doing something different for Christmas. No guests, demos, or framework updates. Instead, Ola Desmurs Linczewska tells a Christmas story.
A (Secure) Christmas Carol is a holiday fairytale for JavaScript and React Native developers. Set on Christmas Eve, it follows Npmezer Scrooge, a senior engineer who believes deadlines matter more than holidays, and warnings can always wait.
Over the course of one long winter night, he’s visited by unexpected guides who show him what his choices look like across time: the optimism of the past, the quiet damage of the present, and a future no one wants.
All technical details, real-world security issues, and references mentioned in the story are explained in the show notes 📚 https://clstk.com/4pEVYwv
We’ll be back in January with regular episodes. Until then, stay kind, stay curious, and have yourself a very merry Christmas.

You Don’t Need a Rewrite, You Need React Native Brownfield | React Universe On Air Coffee Talk #27
Is rewriting your native app really the only way to go cross-platform?
In this Coffee Talk episode, we explore how React Native Brownfield offers a smarter path forward.
Łukasz Chludziński invites Oskar Kwaśniewski and Burak Güner—who work directly on React Native Core and brownfield tooling—to discuss how recent advances in React Native have made brownfield integration far more viable, stable, and scalable.
You’ll learn:
➡️ Why brownfield isn’t what it used to be (goodbye, brittle bridging)
➡️ How `RootViewFactory` and `ReactNativeFactory` APIs simplify setup
➡️ What’s new in React Native Brownfield 1.0.0
➡️ How to keep your architecture clean while integrating React Native
➡️ What this means for modern native stacks like SwiftUI, Jetpack Compose—and future-facing platforms like visionOS
Whether you’re maintaining a legacy app or building for what's next, this episode gives you a blueprint for hybrid success.
