Brownfield React Native used to be a pain. Legacy docs told you to mash everything into a monorepo, deal with flaky integrations, and cross your fingers it would all work. But that approach doesn’t scale, and doesn’t reflect how teams work today.

In this webinar, Michał Pierzchała and Burak Güner walk you through a reimagined approach to brownfield React Native, built for modern teams. You’ll learn how to skip the structural headaches and start embedding React Native in your iOS and Android apps with a modular, dev-friendly setup.
