What Can We Build With React Native?
React Native allows product engineering teams to share logic between web and mobile seamlessly. Choose your app archetype below.
Unified Web & Mobile Platforms
Shared architecture linking your React web application and iOS/Android mobile apps with unified state models, design tokens, and API clients.
Direct C++ JSI Bindings & Instant OTA Updates
By replacing asynchronous JSON serialization with synchronous C++ JavaScript Interface (JSI) pointers, React Native delivers true native UI responsiveness and seamless hot-fix deployments.
// TypeScript Native Component with Fabric
export const AnimatedCartButton = () => {
const scale = useSharedValue(1);
return <AnimatedPressable onPress={handleHapticCheckout} />;
};
