In State of Brownfield in React Native, we’ll look at how engineering teams can introduce React Native and JS into existing native applications, both for the use case of creating a hybrid application architecture and a progressive migration to React Native.

The session walks through practical strategies for phased adoption, cutting-edge tooling, and effective architectural choices. We’ll dig into the real challenges that come with hybrid integration and wrap up with advanced areas like brownfield state and data exchange or optimization techniques.
