Prerequisites

To follow this guide, ensure you have:

Node.js (version 20.0 or higher) and npm installed
React Native CLI (version 0.76 or higher)
An OpenAI API key (As of 2025, you'll need the latest GPT-5 compatible version)
Basic knowledge of React Native and TypeScript

Step 1: Setting Up Your React Native Project

First, let's create a new React Native project:

npx react-native init ChatGPTApp --template react-native-template-typescript
cd ChatGPTApp

Step 2: Installing Dependencies

Install the necessary packages:

npm install @react-navigation/native @react-navigation/stack
npm install react-native-screens react-native-safe-area-context
npm install @react-native-async-storage/async-storage
npm install axios
npm install react-native-dotenv
npm install @react-native-community/netinfo
npm install @react-native-firebase/app @react-native-firebase/analytics

Step 3: Configuring Environment Variables

Create a .env file in your project root to securely store your OpenAI API key:

OPENAI_API_KEY=your_api_key_here

Step 4: Setting Up Navigation

Create a src folder in your project root and add a navigation folder inside it. Create a file named AppNavigator.tsx:

import React from 'react';
import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';
import ChatScreen from '../screens/ChatScreen';
import SettingsScreen from '../screens/SettingsScreen';

const Stack = createStackNavigator();

const AppNavigator = () => {
  return (
    <NavigationContainer>
      <Stack.Navigator>
        <Stack.Screen name="Chat" component={ChatScreen} />
        <Stack.Screen name="Settings" component={SettingsScreen} />
      </Stack.Navigator>
    </NavigationContainer>
  );
};

export default AppNavigator;

Step 5: Creating the Chat Screen

In the src folder, create a screens folder and add ChatScreen.tsx:

import React, { useState, useEffect } from 'react';
import { View, Text, TextInput, TouchableOpacity, FlatList, StyleSheet, ActivityIndicator } from 'react-native';
import { sendMessageToChatGPT } from '../services/chatgptService';
import { useNetInfo } from "@react-native-community/netinfo";
import analytics from '@react-native-firebase/analytics';

interface Message {
  id: string;
  text: string;
  sender: 'user' | 'bot';
}

const ChatScreen = () => {
  const [messages, setMessages] = useState<Message[]>([]);
  const [inputText, setInputText] = useState('');
  const [isLoading, setIsLoading] = useState(false);
  const netInfo = useNetInfo();

  useEffect(() => {
    analytics().logScreenView({
      screen_name: 'ChatScreen',
      screen_class: 'ChatScreen',
    });
  }, []);

  const handleSend = async () => {
    if (inputText.trim() === '') return;
    if (!netInfo.isConnected) {
      alert('No internet connection. Please try again when you're back online.');
      return;
    }

    const userMessage: Message = {
      id: Date.now().toString(),
      text: inputText,
      sender: 'user',
    };

    setMessages((prevMessages) => [...prevMessages, userMessage]);
    setInputText('');
    setIsLoading(true);

    try {
      const botResponse = await sendMessageToChatGPT(inputText);
      const botMessage: Message = {
        id: (Date.now() + 1).toString(),
        text: botResponse,
        sender: 'bot',
      };
      setMessages((prevMessages) => [...prevMessages, botMessage]);
      analytics().logEvent('chat_message_sent', {
        message_length: inputText.length,
        response_length: botResponse.length,
      });
    } catch (error) {
      console.error('Error sending message to ChatGPT:', error);
      alert('An error occurred. Please try again.');
    } finally {
      setIsLoading(false);
    }
  };

  const renderMessage = ({ item }: { item: Message }) => (
    <View style={[styles.messageBubble, item.sender === 'user' ? styles.userBubble : styles.botBubble]}>
      <Text style={styles.messageText}>{item.text}</Text>
    </View>
  );

  return (
    <View style={styles.container}>
      <FlatList
        data={messages}
        renderItem={renderMessage}
        keyExtractor={(item) => item.id}
        contentContainerStyle={styles.messageList}
      />
      <View style={styles.inputContainer}>
        <TextInput
          style={styles.input}
          value={inputText}
          onChangeText={setInputText}
          placeholder="Type a message..."
          editable={!isLoading}
        />
        {isLoading ? (
          <ActivityIndicator size="small" color="#0084FF" />
        ) : (
          <TouchableOpacity style={styles.sendButton} onPress={handleSend}>
            <Text style={styles.sendButtonText}>Send</Text>
          </TouchableOpacity>
        )}
      </View>
    </View>
  );
};

const styles = StyleSheet.create({
  // ... (styles remain the same as in the previous version)
});

export default ChatScreen;

Step 6: Implementing ChatGPT Service

Create a services folder in the src directory and add chatgptService.ts:

import axios from 'axios';
import { OPENAI_API_KEY } from '@env';
import AsyncStorage from '@react-native-async-storage/async-storage';

const API_URL = 'https://api.openai.com/v1/chat/completions';
const MODEL = 'gpt-5'; // Assuming GPT-5 is available in 2025

interface ConversationContext {
  role: string;
  content: string;
}

export const sendMessageToChatGPT = async (message: string): Promise<string> => {
  try {
    const storedContext = await AsyncStorage.getItem('conversationContext');
    let context: ConversationContext[] = storedContext ? JSON.parse(storedContext) : [];

    context.push({ role: 'user', content: message });

    const response = await axios.post(
      API_URL,
      {
        model: MODEL,
        messages: context,
        max_tokens: 150,
        temperature: 0.7,
        top_p: 1,
        frequency_penalty: 0,
        presence_penalty: 0,
      },
      {
        headers: {
          'Content-Type': 'application/json',
          'Authorization': `Bearer ${OPENAI_API_KEY}`,
        },
      }
    );

    const botResponse = response.data.choices[0].message.content.trim();
    context.push({ role: 'assistant', content: botResponse });

    // Keep only the last 10 messages to manage context size
    if (context.length > 10) {
      context = context.slice(-10);
    }

    await AsyncStorage.setItem('conversationContext', JSON.stringify(context));

    return botResponse;
  } catch (error) {
    console.error('Error calling ChatGPT API:', error);
    throw error;
  }
};

Step 7: Creating a Settings Screen

Add a new file SettingsScreen.tsx in the screens folder:

import React, { useState, useEffect } from 'react';
import { View, Text, Switch, StyleSheet } from 'react-native';
import AsyncStorage from '@react-native-async-storage/async-storage';

const SettingsScreen = () => {
  const [isDarkMode, setIsDarkMode] = useState(false);
  const [isNotificationsEnabled, setIsNotificationsEnabled] = useState(true);

  useEffect(() => {
    loadSettings();
  }, []);

  const loadSettings = async () => {
    const darkMode = await AsyncStorage.getItem('darkMode');
    const notifications = await AsyncStorage.getItem('notifications');
    setIsDarkMode(darkMode === 'true');
    setIsNotificationsEnabled(notifications !== 'false');
  };

  const toggleDarkMode = async (value: boolean) => {
    setIsDarkMode(value);
    await AsyncStorage.setItem('darkMode', value.toString());
  };

  const toggleNotifications = async (value: boolean) => {
    setIsNotificationsEnabled(value);
    await AsyncStorage.setItem('notifications', value.toString());
  };

  return (
    <View style={styles.container}>
      <View style={styles.settingItem}>
        <Text style={styles.settingLabel}>Dark Mode</Text>
        <Switch value={isDarkMode} onValueChange={toggleDarkMode} />
      </View>
      <View style={styles.settingItem}>
        <Text style={styles.settingLabel}>Notifications</Text>
        <Switch value={isNotificationsEnabled} onValueChange={toggleNotifications} />
      </View>
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    padding: 20,
    backgroundColor: '#F5F5F5',
  },
  settingItem: {
    flexDirection: 'row',
    justifyContent: 'space-between',
    alignItems: 'center',
    paddingVertical: 15,
    borderBottomWidth: 1,
    borderBottomColor: '#CCCCCC',
  },
  settingLabel: {
    fontSize: 18,
  },
});

export default SettingsScreen;

Step 8: Updating App.tsx

Replace the contents of App.tsx with:

import React from 'react';
import AppNavigator from './src/navigation/AppNavigator';
import { SafeAreaProvider } from 'react-native-safe-area-context';

const App = () => {
  return (
    <SafeAreaProvider>
      <AppNavigator />
    </SafeAreaProvider>
  );
};

export default App;

Step 9: Implementing Advanced Features

1. Conversation History Management

Update chatgptService.ts to include conversation history management:

const MAX_CONTEXT_LENGTH = 10;

export const sendMessageToChatGPT = async (message: string): Promise<string> => {
  try {
    const storedContext = await AsyncStorage.getItem('conversationContext');
    let context: ConversationContext[] = storedContext ? JSON.parse(storedContext) : [];

    context.push({ role: 'user', content: message });

    if (context.length > MAX_CONTEXT_LENGTH) {
      context = context.slice(-MAX_CONTEXT_LENGTH);
    }

    const response = await axios.post(
      API_URL,
      {
        model: MODEL,
        messages: context,
        max_tokens: 150,
      },
      {
        headers: {
          'Content-Type': 'application/json',
          'Authorization': `Bearer ${OPENAI_API_KEY}`,
        },
      }
    );

    const botResponse = response.data.choices[0].message.content.trim();
    context.push({ role: 'assistant', content: botResponse });

    await AsyncStorage.setItem('conversationContext', JSON.stringify(context));

    return botResponse;
  } catch (error) {
    console.error('Error calling ChatGPT API:', error);
    throw error;
  }
};

2. Implementing Typing Indicators

Update ChatScreen.tsx to include a typing indicator:

const [isTyping, setIsTyping] = useState(false);

// In handleSend function
setIsTyping(true);
const botResponse = await sendMessageToChatGPT(inputText);
setIsTyping(false);

// In render
{isTyping && <Text style={styles.typingIndicator}>ChatGPT is typing...</Text>}

3. Error Handling and Retry Mechanism

Implement a robust error handling and retry mechanism in chatgptService.ts:

const MAX_RETRIES = 3;
const RETRY_DELAY = 1000; // 1 second

const sendMessageWithRetry = async (message: string, retryCount = 0): Promise<string> => {
  try {
    return await sendMessageToChatGPT(message);
  } catch (error) {
    if (retryCount < MAX_RETRIES) {
      console.log(`Retrying... Attempt ${retryCount + 1}`);
      await new Promise(resolve => setTimeout(resolve, RETRY_DELAY));
      return sendMessageWithRetry(message, retryCount + 1);
    } else {
      throw error;
    }
  }
};

4. Optimizing Performance

Implement message pagination and local caching:

// In ChatScreen.tsx
const [page, setPage] = useState(1);
const MESSAGES_PER_PAGE = 20;

const loadMoreMessages = async () => {
  const storedMessages = await AsyncStorage.getItem('chatMessages');
  if (storedMessages) {
    const allMessages = JSON.parse(storedMessages);
    const startIndex = (page - 1) * MESSAGES_PER_PAGE;
    const endIndex = startIndex + MESSAGES_PER_PAGE;
    const newMessages = allMessages.slice(startIndex, endIndex);
    setMessages(prevMessages => [...newMessages, ...prevMessages]);
    setPage(prevPage => prevPage + 1);
  }
};

// Use FlatList's onEndReached prop to load more messages
<FlatList
  onEndReached={loadMoreMessages}
  onEndReachedThreshold={0.1}
  // ... other props
/>

5. Enhancing Security

Implement additional security measures:

// Use react-native-keychain for secure storage
import * as Keychain from 'react-native-keychain';

// Store API key securely
await Keychain.setGenericPassword('openai_api_key', OPENAI_API_KEY);

// Retrieve API key
const credentials = await Keychain.getGenericPassword();
const apiKey = credentials ? credentials.password : null;

// Implement rate limiting
const RATE_LIMIT = 5; // 5 requests per minute
const RATE_LIMIT_WINDOW = 60000; // 1 minute in milliseconds

let requestCount = 0;
let windowStart = Date.now();

const checkRateLimit = () => {
  const now = Date.now();
  if (now -
