About This Article

Problem

Engineering teams find it hard to add React Native to apps they've already built in native code. They worry about breaking production systems or having to rebuild their entire iOS and Android applications from scratch.

Solution

Callstack offers a brownfield approach that lets you integrate React Native step by step. You can use RootViewFactory on iOS and platform views on Android to place React Native components directly into your existing native code.

Impact

Teams can move to cross-platform development at their own pace. This cuts down on time to launch and development costs. Your existing native code stays intact and your systems keep running smoothly as you make the switch.
