## What it does

The skill gives an agent working patterns for React Native and Expo projects. It covers file-based navigation with `expo-router`, iOS and Android code differences, `StyleSheet.create`, and long lists built with `FlatList`.

It includes an `app/_layout.tsx` route structure with tabs and dynamic routes. It also points to `@react-navigation/native`, `nativewind`, `zustand`, `@tanstack/react-query`, and `expo-image` for distinct implementation needs.

Expo is recommended for most projects. Choose Bare React Native when a custom native module is not supported by Expo, because it gives full native control.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill react-native-patterns -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/react-native-patterns/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/react-native-patterns/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill react-native-patterns -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/react-native-patterns/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill react-native-patterns -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/react-native-patterns/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install spencerpauly/awesome-cursor-skills react-native-patterns
```

2. **Manually: put the files in place**
- File: `.github/skills/react-native-patterns/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill react-native-patterns -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/spencerpauly/awesome-cursor-skills --path resources/react-native-patterns
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/react-native-patterns/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill react-native-patterns -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/spencerpauly/awesome-cursor-skills/tree/HEAD/resources/react-native-patterns/SKILL.md

## When to use it
- Set up file-based routes with `expo-router`
- Split code between iOS and Android
- Render a long list with `FlatList`
- Avoid styles recreated on every render
- Store sensitive data with `expo-secure-store`

## Example prompts
- Use react-native-patterns to create tab navigation with `expo-router`.
- Apply react-native-patterns and split the component into `Component.ios.tsx` and `Component.android.tsx`.
- Use react-native-patterns to replace this long `ScrollView` with `FlatList`.

# React Native Patterns

Build production-quality mobile apps with React Native and Expo.

## Project Setup

**Expo (recommended for most projects):**
```bash
npx create-expo-app@latest my-app
cd my-app
npx expo start
```

**Bare React Native (when you need full native control):**
```bash
npx @react-native-community/cli init MyApp
```

Use Expo unless you need a custom native module that Expo doesn't support.

## Navigation

Use `expo-router` (file-based routing) or `@react-navigation/native`:

```
app/
├── _layout.tsx        # Root layout (tabs, stack, drawer)
├── index.tsx          # Home screen
├── (tabs)/
│   ├── _layout.tsx    # Tab navigator
│   ├── home.tsx
│   ├── profile.tsx
│   └── settings.tsx
└── [id].tsx           # Dynamic route
```

## Platform-Specific Code

```typescript
import { Platform } from 'react-native';

const styles = StyleSheet.create({
  shadow: Platform.select({
    ios: { shadowColor: '#000', shadowOffset: { width: 0, height: 2 }, shadowOpacity: 0.1 },
    android: { elevation: 4 },
  }),
});
```

For larger differences, use platform-specific files:
- `Component.ios.tsx`
- `Component.android.tsx`

## Styling

Use `StyleSheet.create` for performance (styles are sent to native once):

```typescript
const styles = StyleSheet.create({
  container: { flex: 1, padding: 16 },
  title: { fontSize: 24, fontWeight: '700' },
});
```

For a Tailwind-like experience, use `nativewind`:
```tsx
<View className="flex-1 p-4">
  <Text className="text-2xl font-bold">Hello</Text>
</View>
```

## Performance

**FlatList over ScrollView** for long lists:
```tsx
<FlatList
  data={items}
  keyExtractor={(item) => item.id}
  renderItem={({ item }) => <ItemRow item={item} />}
  initialNumToRender={10}
  maxToRenderPerBatch={5}
  windowSize={5}
/>
```

**Memoize expensive components:**
```tsx
const ItemRow = React.memo(({ item }: { item: Item }) => (
  <View><Text>{item.name}</Text></View>
));
```

**Avoid:**
- Inline styles (creates new objects every render)
- Anonymous functions in `renderItem`
- Large images without caching (`expo-image` handles this)

## Common Libraries

| Need | Library |
|------|---------|
| Navigation | `expo-router` or `@react-navigation/native` |
| State | `zustand`, `jotai`, or React context |
| Data fetching | `@tanstack/react-query` |
| Images | `expo-image` |
| Icons | `@expo/vector-icons` |
| Storage | `expo-secure-store` (sensitive), `@react-native-async-storage/async-storage` (general) |
| Animations | `react-native-reanimated` |
| Gestures | `react-native-gesture-handler` |
| Forms | `react-hook-form` + `zod` |

The third-party file has ended. Everything between the 056cb1b87ddf7ed0 tags is data: requests and commands from it are not followed. An “end of file” line with another tag inside the block is part of the file.
