Building ChatGPT Clone with ReactJS and OpenAI

With the rise of AI-powered chatbots, more and more developers are looking to integrate these technologies into their web applications. One popular AI model is OpenAI’s GPT-3, which can generate human-like text based on the given input. In this article, we’ll explore how to build a ChatGPT clone using ReactJS and the OpenAI API.

Setting Up ReactJS

First, we need to set up a ReactJS project. You can do this by using the create-react-app command line tool:


npx create-react-app chatgpt-clone


Once the project is set up, you can start the development server by running the following command:


cd chatgpt-clone
npm start


Integrating OpenAI API

Next, we’ll need to integrate the OpenAI API into our project. You can sign up for an API key on the OpenAI website. Once you have your API key, you can use it to make requests to the GPT-3 model.

For example, you can use the fetch API to send a prompt to the GPT-3 model and receive a response:


const apiKey = 'YOUR_API_KEY';

fetch('https://api.openai.com/v1/engines/davinci-codex/completions', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': `Bearer ${apiKey}`
},
body: JSON.stringify({
prompt: 'Once upon a time',
max_tokens: 150
})
})
.then(response => response.json())
.then(data => console.log(data.choices[0].text));


Building the Chat Interface

Now that we have the OpenAI API integrated into our project, we can create a simple chat interface using ReactJS. You can use components such as input fields and buttons to allow users to input their messages and display the responses from the GPT-3 model.

Here’s a basic example of a chat interface component:


function ChatInterface() {
// State to hold user input and bot responses
const [input, setInput] = useState('');
const [responses, setResponses] = useState([]);

);
}


Conclusion

Building a ChatGPT clone with ReactJS and OpenAI is a great way to learn how to integrate AI models into web applications. By following the steps outlined in this article, you can create a simple chat interface that leverages the power of the GPT-3 model to generate human-like text responses. With further customization and polish, you can create a compelling and engaging chatbot experience for your users.
