How to use chatGPT in reactjs

Using ChatGPT in a React.js application involves making API requests to the OpenAI API to interact with the model and display its responses in your frontend. Here’s a basic guide on how to do this:

  1. Set Up Your React.js Project: Make sure you have a React.js project set up. You can use Create React App or set up your project manually.
  2. Obtain OpenAI API Key: Sign up for the OpenAI API and obtain your API key. You’ll need this key to make requests to the API.
  3. Make API Requests: In your React component, you can use the fetch or any other suitable method to make API requests to the OpenAI API. You’ll typically create a function that sends a message to the model and retrieves its response. Here’s a simplified example:

import React, { useState } from 'react';

const ChatComponent = () => {
const [messages, setMessages] = useState([]);
const [inputText, setInputText] = useState('');

const handleSendMessage = async () => {
setMessages([...messages, { role: 'user', content: inputText }]);

const response = await fetch('/your-openai-api-endpoint', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': 'Bearer YOUR_API_KEY',
body: JSON.stringify({
model: 'gpt-3.5-turbo',
messages: messages,

const responseData = await response.json();

setMessages([...messages, { role: 'assistant', content: responseData.choices[0].message.content }]);

return (

{, index) => (





export default ChatComponent;

  1. Styling and Enhancements: You can style your chat interface using CSS and enhance the functionality as needed. You might want to handle user inputs, scroll to the latest messages, and format the conversation for better readability.
  2. Error Handling and Security: Ensure proper error handling in your API requests. It’s also important to keep your API key secure. In a production environment, consider using environment variables to store your API key.

Remember that this is a basic example, and you can customize and expand upon it to create a more robust and interactive chat interface using ChatGPT in your React.js application.
