React Native Development Skill

Overview

This skill provides deep integration with the React Native ecosystem for cross-platform mobile development. It enables execution of React Native CLI commands, component generation, build optimization, and comprehensive debugging capabilities.

Allowed Tools

• bash - Execute React Native CLI, Expo CLI, and npm/yarn commands
• read - Analyze React Native project files, configurations, and components
• write - Generate and modify React Native components and configurations
• edit - Update existing React Native code and configurations
• glob - Search for React Native components and configuration files
• grep - Search for patterns in React Native codebase

• mobile-performance-optimization.js - Performance tuning

Dependencies

Required

• Node.js 18+
• npm or yarn package manager
• React Native CLI (npx react-native)
• Watchman (macOS)

Optional

• Expo CLI (npx expo)
• Android Studio with Android SDK
• Xcode (macOS only)
• Flipper
• Reactotron

Metro Configuration

// metro.config.js
const { getDefaultConfig, mergeConfig } = require('@react-native/metro-config');

const config = {
  transformer: {
    getTransformOptions: async () => ({
      transform: {
        experimentalImportSupport: false,
        inlineRequires: true,
      },
    }),
  },
};

module.exports = mergeConfig(getDefaultConfig(__dirname), config);

Usage Examples

Initialize Project

# Create new React Native project
npx react-native init MyApp --template react-native-template-typescript

# Or with Expo
npx create-expo-app MyApp --template expo-template-blank-typescript

Generate Component

// src/components/Button/Button.tsx
import React from 'react';
import { TouchableOpacity, Text, StyleSheet, ViewStyle, TextStyle } from 'react-native';

interface ButtonProps {
  title: string;
  onPress: () => void;
  variant?: 'primary' | 'secondary';
  disabled?: boolean;
}

export const Button: React.FC<ButtonProps> = ({
  title,
  onPress,
  variant = 'primary',
  disabled = false,
}) => {
  return (
    <TouchableOpacity
      style={[styles.button, styles[variant], disabled && styles.disabled]}
      onPress={onPress}
      disabled={disabled}
      activeOpacity={0.8}
    >
      <Text style={[styles.text, [`${}`]]}>{title}
    
  );
};

 styles = .({
  : {
    : ,
    : ,
    : ,
    : ,
  },
  : {
    : ,
  },
  : {
    : ,
    : ,
    : ,
  },
  : {
    : ,
  },
  : {
    : ,
    : ,
  },
  : {
    : ,
  },
  : {
    : ,
  },
});

Configure Navigation

// src/navigation/RootNavigator.tsx
import React from 'react';
import { NavigationContainer } from '@react-navigation/native';
import { createNativeStackNavigator } from '@react-navigation/native-stack';
import { HomeScreen } from '../screens/HomeScreen';
import { DetailsScreen } from '../screens/DetailsScreen';

export type RootStackParamList = {
  Home: undefined;
  Details: { id: string };
};

const Stack = createNativeStackNavigator<RootStackParamList>();

export const RootNavigator: React.FC = () => {
  return (
    <NavigationContainer>
      <Stack.Navigator initialRouteName="Home">
        <Stack.Screen name="Home" component={HomeScreen} />
        <Stack.Screen = = />
      
    
  );
};

Configure Redux Store

// src/store/store.ts
import { configureStore } from '@reduxjs/toolkit';
import { setupListeners } from '@reduxjs/toolkit/query';
import { api } from './api';
import userReducer from './slices/userSlice';

export const store = configureStore({
  reducer: {
    user: userReducer,
    [api.reducerPath]: api.reducer,
  },
  middleware: (getDefaultMiddleware) =>
    getDefaultMiddleware().concat(api.middleware),
});

setupListeners(store.dispatch);

export type RootState = ReturnType<typeof store.getState>;
export type AppDispatch = typeof store.dispatch;

Quality Gates

Error Handling

Common Issues

1. Metro bundler cache issues

   npx react-native start --reset-cache
   

2. iOS pod installation failures

   cd ios && pod install --repo-update
   

3. Android Gradle sync issues

   cd android && ./gradlew clean
   

4. Native module linking issues

   npx react-native link
   # Or for newer versions, use autolinking
