Creating Powerful Chatbots: A Developer’s Guide to Integrating ChatGPT and React Native

In today’s fast-paced world, the demand for chatbots and virtual assistants has been growing rapidly. Chatbots have become essential for businesses to provide round-the-clock customer support and engagement. One of the most popular chatbots in the market today is ChatGPT, an AI-powered language model that is known for its natural language processing capabilities.

The demand for intelligent chatbots is skyrocketing as the world increasingly relies on technology. Chatbots are now used in a variety of industries, from customer service to healthcare. ChatGPT is a state-of-the-art chatbot gaining popularity due to its natural language processing capabilities.
In this step-by-step guide, we’ll explore how to integrate ChatGPT with a React Native app. React Native is a popular framework for building mobile applications, and by incorporating it with ChatGPT, we can create a powerful and intelligent chatbot that can help users with their queries and tasks. We will start with setting up the environment and then move on to creating the chatbot UI using React Native components. We will then integrate ChatGPT API and show how to send and receive messages.

This guide is perfect for developers who want to explore the world of chatbots and learn how to integrate ChatGPT with their mobile applications. Whether you’re an experienced developer or just starting, this guide will provide you with the knowledge and tools you need to build intelligent chatbots using React Native and ChatGPT.

By the end of this guide, you will have a fully functional chatbot integrated into your React Native app. Your users will be able to engage with your app through natural language and receive personalized responses, improving their overall experience.


Step 1: Setting up the Environment

Before we start, make sure you have the following tools installed on your machine:

1) Node.js
2) npm or yarn
3) React Native CLI

Once you have the tools installed, create a new React Native project using the following command:

npx react-native init ChatGPTIntegration

This will create a new React Native project named ChatGPTIntegration.

Step 2: Creating the Chatbot UI

To create the chatbot UI, we will use React Native Gifted Chat, a ready-made UI component for chat applications. Install React Native Gifted Chat using the following command:

npm install react-native-gifted-chat

Next, import GiftedChat into your React Native project and add the following code to your App.js file:

import { GiftedChat } from 'react-native-gifted-chat';
import React, { useState } from 'react';

export default function App() {
const [messages, setMessages] = useState([]);

const onSend = (newMessages = []) => {
setMessages(GiftedChat.append(messages, newMessages));

return (
onSend={(newMessages) => onSend(newMessages)}
_id: 1,

This will render a basic chat UI in your React Native app.

Step 3: Integrating ChatGPT API

To integrate ChatGPT API, we will use the Axios library, which is a popular HTTP client for making API requests. Install Axios using the following command:

npm install axios

Next, import Axios into your React Native project and add the following code to your App.js file:

import axios from 'axios';

const CHATGPT_API_URL = '';

const generateResponse = async (text) => {
const response = await, {
prompt: `The following is a conversation with an AI assistant. The assistant is helpful, creative, clever, and very friendly.
Human: ${text}
max_tokens: 150,
temperature: 0.7,
n: 1,
stop: 'Human:',
}, {
headers: {
'Content-Type': 'application/json',
'Authorization': `Bearer ${YOUR_API_KEY}`,

const { choices } =;
const { text: generatedText } = choices[0];

return generatedText.trim();

Replace YOUR_API_KEY with your ChatGPT API key.

Step 4: Sending and Receiving Messages

To send and receive messages, we will modify the onSend function in the App.js file as follows:

onSend(messages = []) {
this.setState(previousState => ({
messages: GiftedChat.append(previousState.messages, messages),
}), () => {
// send the user message to ChatGPT API`${API_URL}/predict`, { text: messages[0].text })
.then(response => {
const botMessage = {
_id: Math.round(Math.random() * 1000000),
createdAt: new Date(),
user: BOT_USER,

this.setState(previousState => ({
messages: GiftedChat.append(previousState.messages, botMessage),
.catch(error => {

The onSend function takes an array of messages as an argument. We first append the new messages to the existing messages using the GiftedChat.append function.
Next, we send the user’s message to the ChatGPT API using Axios, a popular library for making HTTP requests. The API URL is defined in the API_URL constant.
The response from the API contains the bot’s message, which we then create as a new message object with a random ID, the text of the message, the current date, and the BOT_USER object as the user.
Finally, we append the bot’s message to the existing messages and update the state of the component.

Step 5: Styling the Chatbot UI

We can add some basic styles to the chatbot UI to make it more visually appealing. We will create a new file called ChatStyles.js the root of our project and add the following code:

import { StyleSheet } from 'react-native';

export const styles = StyleSheet.create({
chatContainer: {
flex: 1,
backgroundColor: '#fff',
chatHeader: {
height: 60,
backgroundColor: '#5BC0EB',
justifyContent: 'center',
alignItems: 'center',
chatHeaderText: {
color: '#fff',
fontSize: 20,
fontWeight: 'bold',
sendButton: {
backgroundColor: '#5BC0EB',
justifyContent: 'center',
alignItems: 'center',
borderRadius: 25,
height: 50,
width: 50,
sendIcon: {
color: '#fff',
fontSize: 24,

These styles define the appearance of the chatbot UI, including the background color, header, and send button.
To use these styles, we import them into the App.js file and apply them to the appropriate components:

import { styles } from './ChatStyles';

render() {
return (
<View style={styles.container}>
onSend={messages => this.onSend(messages)}
renderSend={props => (
<Send {...props}>
<View style={styles.sendButton}>
<Icon name="send" style={styles.sendIcon} />
renderLoading={() => <ActivityIndicator size="large" color="#5BC0EB" />}
renderChatFooter={() => <Text style={{ textAlign: 'center' }}>Powered by ChatGPT</Text>}
placeholder="Type your message here..."
scrollToBottomComponent={() => (
<Icon name="chevron-down" size={36} color="#5BC0EB" />

We apply the container style to the top-level View component, and the individual styles such as chatContainer and inputToolbarContainer to their respective components.

Step 5: Testing the App

With the integration complete, we can now test our app. To do this, we need to start the React Native app in the simulator or on a physical device. We can do this using the following command:

npx react-native run-ios
npx react-native run-android

depending on the platform we are targeting.
Once the app is running, we can test the chatbot by typing messages and seeing the responses from ChatGPT. We can also test the various customizations we made, such as changing the chat bubble colors and input toolbar styles.


In this tutorial, we have learned how to integrate ChatGPT with a React Native app. We started by setting up the environment and creating the chatbot UI using Gifted Chat. We then integrated the ChatGPT API and customized the chatbot UI with custom chat bubbles and input toolbars. Finally, we tested the app and saw the chatbot in action.
This integration opens up a world of possibilities for chatbot development on mobile platforms. By using ChatGPT, we can create intelligent chatbots that can understand natural language and provide meaningful responses to users. With the popularity of chatbots increasing in various industries, this integration is a valuable skill for developers to have in their toolkits.
