React Native lets you build iOS and Android apps from one JavaScript and React codebase. This visual guide covers components, the bridge to native, navigation, styling, and the tradeoffs of cross-platform development.
Build iOS and Android apps from one React codebase.
Share most code across platforms.
Same components and hooks you know from React.
View, Text, and Image map to real native UI.
Style with JavaScript objects, similar to CSS.
React Native uses Flexbox for layouts.
Respond to taps and gestures.
React Navigation moves between screens.
Use hooks, context, or libraries for state.
Fetch APIs just like in web React.
Expo simplifies building and running React Native apps.
Access device features via native code.
JS communicates with native through a bridge.
Avoid heavy work on the JS thread.
Faster to build, but native can be more optimized.
Both are cross-platform with different languages.
Use dev tools and fast refresh.
Build and submit to both app stores.
Great for shared apps and faster delivery.
Start with Expo for the easiest setup.
