Building Cross-Platform Federated Modules with React, React Native, and Re.Pack
Building Cross-Platform Federated Modules with React, React Native, and Re.Pack
Discover how Module Federation and Re.Pack enable true cross-platform super apps with React Native. Learn best practices and real-world strategies for dynamic, modular architectures.
Building Cross-Platform Federated Modules with React, React Native, and Re.Pack

Module Federation has revolutionized the way we build web applications—allowing teams to split code into independently deployed modules that can be loaded on demand. This architecture is the backbone of modern super apps.
Now, thanks to Re.Pack, a bundler built by Callstack as an alternative to Metro, the same dynamic architecture is possible in React Native.
In this talk, Mike will explore how Module Federation empowers developers to write modular code that runs seamlessly across platforms—from web to mobile. Whether you're building a new super app or looking to migrate parts of an existing native stack to React Native, this session will cover:
- What Module Federation is and how it works
- Why it’s a game-changer for super apps and microfrontends
- How Re.Pack brings this power to React Native
- Best practices for cross-platform federation
- Real-world examples and lessons learned
Get ready to rethink your app architecture—and ship faster across platforms.
