Everything You Need To Know About React Native Brownfield

React Native Brownfield is a library that simplifies integrating React Native into existing native Android and iOS apps without full rewrites. The 1.0.0 release introduces a view loader API supporting SwiftUI views, UIKit view controllers, Jetpack Compose views, Android fragments, and more. It supports two integration strategies: a monorepo approach for simpler setups, and a separate-repository approach where React Native is packaged as .xcframework and .aar files for better encapsulation. The library handles lifecycle management, flexible initialization APIs, and is recommended for teams gradually transitioning to React Native, replacing webviews, or sharing UI components across platforms.
