| description | React Native framework for building native mobile apps with React. Use when building iOS/Android apps, working with native components, handling touch interactions, animations, or platform APIs. |
React Native
The skill is based on React Native, generated at 2026-01-31.
React Native lets you build mobile apps using only JavaScript. It uses the same design as React, letting you compose a rich mobile UI from declarative components. With React Native, you don't build a "mobile web app", an "HTML5 app", or a "hybrid app". You build a real mobile app that's indistinguishable from an app built using Objective-C or Java.

Key Recommendations
- Use StyleSheet.create() for all styles instead of inline objects
- Use FlatList instead of ScrollView for long lists
- Enable useNativeDriver for animations when possible (transform, opacity)
- Use Pressable for new touch interactions (preferred over Touchable components)
- Handle platform differences with Platform.select() and Platform.OS
- Test on real devices - simulator behavior may differ from actual devices
- Optimize list performance with getItemLayout for fixed-height items
- Use TypeScript for better type safety and developer experience
