This skill should be used when writing, reviewing, or refactoring Expo React Native code to ensure optimal performance patterns. Triggers on tasks involving React Native components, navigation, lists, images, animations, bundle optimization, or mobile performance improvements.\n---\n\n# Community Expo React Native Best Practices\n\nComprehensive performance optimization guide for Expo React Native applications. Contains 54 rules across 9 categories, prioritized by impact to guide automated refactoring and code generation.\n\n## When to Apply\n\nReference these guidelines when:\n- Writing new Expo React Native components\n- Optimizing app startup and Time to Interactive\n- Implementing lists, images, or animations\n- Reducing bundle size and memory usage\n- Reviewing code for mobile performance issues\n\n## Rule Categories by Priority\n\n| Priority | Category | Impact | Prefix |\n|----------|----------|--------|--------|\n| 1 | Launch Time Optimization | CRITICAL | `launch-` |\n| 2 | Bundle Size Optimization | CRITICAL | `bundle-` |\n| 3 | List Virtualization | HIGH | `list-` |\n| 4 | Image Optimization | HIGH | `image-` |\n| 5 | Data Fetching Patterns | HIGH | `data-` |\n| 6 | Navigation Performance | MEDIUM-HIGH | `nav-` |\n| 7 | Re-render Prevention | MEDIUM | `rerender-` |\n| 8 | Animation Performance | MEDIUM | `anim-` |\n| 9 | Memory Management | LOW-MEDIUM | `mem-` |\n\n## Quick Reference\n\n### 1. Launch Time Optimization (CRITICAL)\n\n- `launch-splash-screen-control` - Control splash screen visibility during asset loading\n- `launch-preload-critical-assets` - Preload fonts and images during splash\n- `launch-hermes-engine` - Use Hermes engine for faster startup\n- `launch-defer-non-critical` - Defer non-critical initialization\n- `launch-new-architecture` - Enable New Architecture for synchronous native communication\n- `launch-minimize-root-imports` - Minimize imports in root App component\n\n### 2.
