You Don’t Need a Rewrite, You Need React Native Brownfield

Is rewriting your app from scratch the only path forward? Not quite.

In this episode of Coffee Talk, we dive into a smarter alternative: React Native Brownfield integration. It’s a practical way to bring cross-platform power into existing native apps—without blowing up your architecture or CI pipeline.

Join Łukasz Chludziński and his guests, Oskar Kwaśniewski and Burak Güner—core contributors to React Native and the minds behind brownfield tooling—as they unpack how modern integrations are evolving.

With firsthand experience building at the edge of React Native Core, they walk through the patterns, tools, and decisions that make large-scale brownfield integrations viable today.

Reinventing React Native Brownfield

Brownfield used to be brittle: manual bridging, chaotic initialization, version mismatches. But that’s no longer the story. Thanks to recent updates in React Native Core—including factory APIs like RootViewFactory  and ReactNativeFactory—brownfield setups are cleaner and easier to scale.

Even better, with the release of React Native Brownfield 1.0.0, Callstack’s library now supports:

• A simplified, more predictable API
• Packaging as a native framework
• Compatibility with SwiftUI and Jetpack Compose

These updates make it easier to reason about hybrid apps, reduce integration debt, and align React Native with modern native paradigms.

What you’ll learn about brownfield app development

• What really separates greenfield from brownfield—beyond the buzzwords
• How new factory APIs eliminate boilerplate and make setup consistent
• Tips to avoid side effects and keep your codebase clean
• Why native framework packaging makes modular adoption easier
• How this approach works for both legacy apps and emerging platforms like visionOS
• Where the performance trade-offs live—and how to manage them
