How To Integrate OpenAI's GPT models into a ReactJS application

To add OpenAI's GPT models to a ReactJS app, you usually use the OpenAI GPT API. Keep in mind that details might change, so always check the newest OpenAI documentation for the most accurate information.

Steps to Integrate OpenAI GPT in ReactJS:

  1. Sign Up and Get An API Key:

    • Sign up for an account on the OpenAI platform.

    • Follow the instructions to get an API key. Keep in mind that when I last checked, API access wasn't free, and you might need to join a waitlist or apply for access.

  2. Review OpenAI documentation:

  3. Install the necessary libraries:

    • Install any necessary libraries for making HTTP requests in React, such as axios or the built-in fetch.
    npm install axios
  1. Make API Requests:

    • With React, make requests to the OpenAI GPT API. Usually, send a POST request to the API endpoint with your API key and the text you want the model to create or finish.
    import React, { useState } from 'react';
    import axios from 'axios';

    const GPTIntegration = () => {
      const [response, setResponse] = useState('');

      const makeRequest = async () => {
        try {
          const apiKey = 'YOUR_API_KEY';
          const prompt = 'Your prompt text here...';

          const apiUrl = '';

          const { data } = await
            { prompt, max_tokens: 150 },
            { headers: { Authorization: `Bearer ${apiKey}` } }

        } catch (error) {
          console.error('Error making API request:', error);

      return (
          <button onClick={makeRequest}>Generate Text</button>
          <p>Response: {response}</p>

    export default GPTIntegration;
  1. Handle Responses:

    • Handle the API responses according to your application's needs. The generated text will be in the data.choices[0].text property of the response.
  2. Error Handling and Security:

    • Implement proper error handling and security practices. Ensure that you keep your API key secure and do not expose it publicly in client-side code.

Keep up with the OpenAI documentation for updates or new features. Also, remember that the GPT API's availability and details might change over time. So, always check the latest OpenAI resources for the most accurate information.

While working in Vite, how to configure API keys?

With Vite (a tool for modern web development) in a React project, setting up API keys or private information is different than in a regular React project. Vite uses a .env file for environment variables, which you can use in your Vite configuration.

Here's how to set up API keys in a React project using Vite:

  1. Create an Environment Variables File: Create a file named .env in the root of your project. Add your API key as a variable in this file.

    • The REACT_APP_ prefix is needed for the variable to work in a Create React App (CRA)-like setting. Vite adds the VITE_ prefix to environment variables automatically, so you don't have to do it yourself.Access Environment Variables in Code: In your React components or other code files, you can access these environment variables using import.meta.env.
    const apiKey = import.meta.env.REACT_APP_OPENAI_API_KEY;
  1. Configure Vite to Use Environment Variables: In your vite.config.js file, you can use the dotenv library to load the environment variables.

    Install dotenv if you haven't already:

     npm install dotenv --save-dev

    In your vite.config.js:

     import dotenv from 'dotenv';
     import react from '@vitejs/plugin-react';
     export default {
       plugins: [react()],

    Ensure that the dotenv.config() call is at the top of your vite.config.js file.

  2. Use Environment Variables in API Requests: When making API requests, use the environment variables in your code.

     import axios from 'axios';
     const apiKey = import.meta.env.REACT_APP_OPENAI_API_KEY;
     const apiUrl = '';
     const { data } = await
       { prompt: 'Your prompt text here...', max_tokens: 150 },
       { headers: { Authorization: `Bearer ${apiKey}` } }

Make sure to keep your .env file safe, especially if it has important info like API keys. Don't add your .env file to version control systems, and make sure it's in your .gitignore file.

Always refer to the official Vite documentation for the latest information on working with environment variables in Vite.
