React Native Skills Comprehensive best practices for React Native and Expo applications. Contains rules across multiple categories covering performance, animations, UI patterns, and platform-specific optimizations. When to Apply Reference these guidelines when: Building React Native or Expo apps Optimizing list and scroll performance Implementing animations with Reanimated Working with images and media Configuring native modules or fonts Structuring monorepo projects with native dependencies Rule Categories by Priority Priority Category Impact Prefix 1 List Performance CRITICAL list-performance- 2 Animation HIGH animation- 3 Navigation HIGH navigation- 4 UI Patterns HIGH ui- 5 State Management MEDIUM react-state- 6 Rendering MEDIUM rendering- 7 Monorepo MEDIUM monorepo- 8 Configuration LOW fonts- , imports- Quick Reference 1. List Performance (CRITICAL) list-performance-virtualize - Use FlashList for large lists list-performance-item-memo - Memoize list item components list-performance-callbacks - Stabilize callback references list-performance-inline-objects - Avoid inline style objects list-performance-function-references - Extract functions outside render list-performance-images - Optimize images in lists list-performance-item-expensive - Move expensive work outside items list-performance-item-types - Use item types for heterogeneous lists 2. Animation (HIGH) animation-gpu-properties - Animate only transform and opacity animation-derived-value - Use useDerivedValue for computed animations animation-gesture-detector-press - Use Gesture.Tap instead of Pressable 3. Navigation (HIGH) navigation-native-navigators - Use native stack and native tabs over JS navigators 4. UI Patterns (HIGH) ui-expo-image - Use expo-image for all images ui-image-gallery - Use Galeria for image lightboxes ui-pressable - Use Pressable over TouchableOpacity ui-safe-area-scroll - Handle safe areas in ScrollViews ui-scrollview-content-inset - Use contentInset for headers ui-menus - Use native context menus ui-native-modals - Use native modals when possible ui-measure-views - Use onLayout, not measure() ui-styling - Use StyleSheet.create or Nativewind 5. State Management (MEDIUM) react-state-minimize - Minimize state subscriptions react-state-dispatcher - Use dispatcher pattern for callbacks react-state-fallback - Show fallback on first render react-compiler-destructure-functions - Destructure for React Compiler react-compiler-reanimated-shared-values - Handle shared values with compiler 6. Rendering (MEDIUM) rendering-text-in-text-component - Wrap text in Text components rendering-no-falsy-and - Avoid falsy && for conditional rendering 7. Monorepo (MEDIUM) monorepo-native-deps-in-app - Keep native dependencies in app package monorepo-single-dependency-versions - Use single versions across packages 8. Configuration (LOW) fonts-config-plugin - Use config plugins for custom fonts imports-design-system-folder - Organize design system imports js-hoist-intl - Hoist Intl object creation How to Use Read individual rule files for detailed explanations and code examples: rules/list-performance-virtualize.md rules/animation-gpu-properties.md Each rule file contains: Brief explanation of why it matters Incorrect code example with explanation Correct code example with explanation Additional context and references Full Compiled Document For the complete guide with all rules expanded: AGENTS.md
