About This Article
When teams add React Native to existing native applications, they run into trouble keeping state in sync between the native code and React layers. It takes careful work to coordinate across platform boundaries.
Callstack built the Brownie library to solve this. It's a type-safe shared state solution that syncs native and React state from a single TypeScript schema, so you don't have to manage state manually across platforms.
Brownie lets you share code across platforms right away in brownfield apps. It provides type-safe state bridges that cut down on integration work and help native and React Native implementations reach feature parity faster.
