## What it does

This skill covers building iOS and Android apps from one React Native codebase. It sets out navigation with React Navigation, state management through Redux or Context API, API integration, and handling platform differences. Next to `SKILL.md` sits a `references/` folder with four write-ups: project setup and navigation, Redux state, Axios requests, and functional components with hooks.

The rules are blunt. Functional components with hooks. Error and loading states on every fetch. `FlatList` for long lists, `StyleSheet` instead of inline styles, TypeScript for types. API endpoints belong in environment variables, not in the source. Test on both platforms, not just the simulator.

The skill does not scaffold a project or install anything. You need React Native, React Navigation, Redux, Axios and `@expo/vector-icons` in place first, otherwise the examples in `references/` will not run. Worth checking your library versions against the ones in those examples, since the React Navigation API shifts between major releases.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill react-native-app -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill react-native-app -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill react-native-app -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aj-geddes/useful-ai-prompts react-native-app
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill react-native-app -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aj-geddes/useful-ai-prompts --path skills/react-native-app
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill react-native-app -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/aj-geddes/useful-ai-prompts/tree/HEAD/skills/react-native-app/SKILL.md

## When to use it
- ship one app to iOS and Android without two codebases
- wire up a stack navigator and bottom tabs
- move screen state into Redux or Context API
- call a backend through Axios with error handling
- split platform-specific code for iOS and Android

## Example prompts
- Build a profile screen in React Native that loads data with Axios and handles loading and error states
- Set up navigation: a stack with Home and Details screens plus bottom tabs
- Move the cart state from local useState to Redux Toolkit

## Overview

Create robust cross-platform mobile applications using React Native with modern development patterns including navigation, state management, API integration, and native module handling.

## When to Use

- Building iOS and Android apps from single codebase
- Rapid prototyping for mobile platforms
- Leveraging web development skills for mobile
- Sharing code between React Native and React Web
- Integrating with native modules and APIs

## Quick Start

Minimal working example:

```javascript
// Navigation with React Navigation
import React from "react";
import { NavigationContainer } from "@react-navigation/native";
import { createNativeStackNavigator } from "@react-navigation/native-stack";
import { createBottomTabNavigator } from "@react-navigation/bottom-tabs";
import { Ionicons } from "@expo/vector-icons";

const Stack = createNativeStackNavigator();
const Tab = createBottomTabNavigator();

function HomeStack() {
  return (
    <Stack.Navigator
      screenOptions={{
        headerStyle: { backgroundColor: "#6200ee" },
        headerTintColor: "#fff",
        headerTitleStyle: { fontWeight: "bold" },
      }}
    >
      <Stack.Screen
        name="Home"
        component={HomeScreen}
        options={{ title: "Home Feed" }}
      />
      <Stack.Screen name="Details" component={DetailsScreen} />
// ... (see reference guides for full implementation)
```

## Reference Guides

Detailed implementations in the `references/` directory:

| Guide | Contents |
|---|---|
| [Project Setup & Navigation](references/project-setup-navigation.md) | Project Setup & Navigation |
| [State Management with Redux](references/state-management-with-redux.md) | State Management with Redux |
| [API Integration with Axios](references/api-integration-with-axios.md) | API Integration with Axios |
| [Functional Component with Hooks](references/functional-component-with-hooks.md) | Functional Component with Hooks |

## Best Practices

### ✅ DO

- Use functional components with React Hooks
- Implement proper error handling and loading states
- Use Redux or Context API for state management
- Leverage React Navigation for routing
- Optimize list rendering with FlatList
