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:

// 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)

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
• Handle platform-specific code elegantly
• Use TypeScript for type safety
• Test on both iOS and Android
• Use environment variables for API endpoints
• Implement proper memory management

❌ DON'T

• Use inline styles excessively (use StyleSheet)
• Make API calls without error handling
• Store sensitive data in plain text
• Ignore platform differences
• Create large monolithic components
• Use index as key in lists
• Make synchronous operations
• Ignore battery optimization
• Deploy without testing on real devices
• Forget to unsubscribe from listeners
