The article introduces practical tools and real-world examples from companies like Zalando and Shopify that successfully adopted this strategy.
Key Takeaways
- Brownfield lets you integrate React Native without rewriting your entire app
- Shopify achieved 86% code unification using this migration approach
- New tools like Brownie enable type-safe state sharing between native and React
- RootViewFactory simplifies iOS integration and reduces boilerplate code
Brownfield React Native integration enables teams to adopt cross-platform development incrementally, reducing risk and time-to-market while preserving existing native code.
About This Article
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.
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.
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.
