Adopting cross-platform React Native at scale: Zalando's learnings from the ongoing migration

This talk dives deep into technical details of our ongoing React Native adoption for the Zalando App. It will cover our non-standard brownfield integration strategy and the challenges we faced achieving seamless interoperability with existing native app code. We'll detail our architectural choices, including the use of React Strict DOM as a core foundation for future web and mobile unification. Plus, we'll share insights into the design and tradeoffs of reusing Zalando's existing internal React framework to extend React Native's capabilities and establish the same overarching patterns across platforms, bridging the gap between our web and app products.
