Adopting React Native doesn’t mean starting from scratch. In this webinar, Callstack’s CTO Mike Grabowski and Burak Güner, the maintainer of React Native Builder Bob maintainer, share practical ways to add React Native to existing native apps. They explain how to speed up development and reduce duplication across iOS and Android, without giving up native performance or control.

This session is especially useful for developers working on mobile apps and for tech leads looking to help their teams move faster with fewer resources.

What you’ll learn about Brownfield React Native and why it matters for your team

Adding React Native to a native app might seem complex, but the right approach can save time and effort. If your team is maintaining separate codebases or using web views to keep features in sync, this session will show how to bring React Native into the mix without disrupting existing workflows.

Brownfield integration strategies that actually work

  • When using React Native in a native app makes sense and when it does not.
  • Two ways to get started: a quick setup for testing and early adoption and a more advanced method for long-term use in larger teams.
  • How to reduce friction between React Native and native development teams.

Building a shared codebase without hurting performance

  • How React Native turns JavaScript into native UI components.
  • Why separating responsibilities between native and React Native code helps you move faster.
  • How to mix React Native with native code while keeping the user experience consistent.

Best practices for maintainability, performance, and team collaboration

  • How to organize your project for easier maintenance and clearer structure.
  • How to create safe, type-checked connections between native and React Native code.
  • How to deliver prebuilt React Native features that native teams can use without setup headaches.
  • How to track performance and user experience with real-world data.

Watch the recording now to learn how your team can deliver cross-platform features faster, without a full rewrite or extra complexity.
