Once upon a time, brownfield React Native meant cramming iOS, Android, and JavaScript into a single monorepo—and dealing with all the headaches that came with it. That approach worked... until it didn’t.

In this webinar, Callstack’s Michał Pierzchała and Burak Güner will walk you through why we created React Native Brownfield in the first place, and why we’ve since modernized it. You’ll get a clear look at what the tool can do for you today, where it still needs a helping hand (looking at you, XCFrameworks and AARs), and how upcoming updates via React Native Enterprise Framework are about to make things even smoother.

We’ll also cover how we’d architect a brownfield setup if we were starting from scratch in 2025—what we’d include, what we’d modularize, and how we’d keep it all maintainable.

Expect a side-by-side look at the "before" and "after" of brownfield development—and walk away with a playbook for doing it the clean way.
