Why React Native + Expo?
If you already know React, React Native lets you build native mobile apps for both iOS and Android from a single codebase. Expo is the framework that simplifies the development workflow significantly.
Expo Router - File-Based Routing
Just like Next.js App Router, Expo Router brings file-based routing to mobile. Navigation becomes declarative and far easier to maintain.
EAS Build & Submit
Expo Application Services (EAS) lets you build and submit your app to the stores from the cloud. You no longer need a Mac to build an iOS app.
NFC Payments with React Native
I built Monie - a fintech app with NFC payments using React Native. The experience is quite smooth, although NFC on iOS still has some limitations.
Performance Optimization Tips
Use FlashList instead of FlatList, optimize re-renders with React.memo, and leverage Reanimated for smooth 60fps animations.
