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 listslist-performance-item-memo- Memoize list item componentslist-performance-callbacks- Stabilize callback referenceslist-performance-inline-objects- Avoid inline style objectslist-performance-function-references- Extract functions outside renderlist-performance-images- Optimize images in listslist-performance-item-expensive- Move expensive work outside itemslist-performance-item-types- Use item types for heterogeneous lists
2. Animation (HIGH)
animation-gpu-properties- Animate only transform and opacityanimation-derived-value- Use useDerivedValue for computed animationsanimation-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 imagesui-image-gallery- Use Galeria for image lightboxesui-pressable- Use Pressable over TouchableOpacityui-safe-area-scroll- Handle safe areas in ScrollViewsui-scrollview-content-inset- Use contentInset for headersui-menus- Use native context menusui-native-modals- Use native modals when possibleui-measure-views- Use onLayout, not measure()ui-styling- Use StyleSheet.create or Nativewind
5. State Management (MEDIUM)
react-state-minimize- Minimize state subscriptionsreact-state-dispatcher- Use dispatcher pattern for callbacksreact-state-fallback- Show fallback on first renderreact-compiler-destructure-functions- Destructure for React Compilerreact-compiler-reanimated-shared-values- Handle shared values with compiler
6. Rendering (MEDIUM)
rendering-text-in-text-component- Wrap text in Text componentsrendering-no-falsy-and- Avoid falsy && for conditional rendering
7. Monorepo (MEDIUM)
monorepo-native-deps-in-app- Keep native dependencies in app packagemonorepo-single-dependency-versions- Use single versions across packages
8. Configuration (LOW)
fonts-config-plugin- Use config plugins for custom fontsimports-design-system-folder- Organize design system importsjs-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
