# 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)
