Building a ChatGPT Clone with Next.js, Supabase, and Jotai

If you’ve ever wanted to build your own chatbot, you’ve probably heard of OpenAI’s GPT-3. It’s a powerful language model that can generate human-like text based on prompts you give it. In this tutorial, we’ll show you how to build a simple chatbot using Next.js, Supabase, and Jotai.

What you’ll need

• Node.js and npm/yarn installed on your machine
• A Supabase account for storing chat data
• Basic knowledge of React and state management with Jotai

Setting up the project

First, create a new Next.js project by running the following commands in your terminal:

npx create-next-app chatgpt-clone
cd chatgpt-clone
yarn add @supabase/supabase-js jotai

Creating the chat interface

Next, create a new file called ChatInterface.js and add the following code:

        {`import React from 'react';
import { useAtom } from 'jotai';
import { supabase } from '../lib/supabase';

const ChatInterface = () => {
  const [messages, setMessages] = useAtom(messagesAtom);
  const [inputValue, setInputValue] = useAtom(inputValueAtom);

  const handleSubmit = async (e) => {
    e.preventDefault();
    if (inputValue.trim() === '') return;
    const { data, error } = await supabase
      .from('messages')
      .insert({ text: inputValue });

    if (error) {
      console.error('Error sending message:', error);
    } else {
      setMessages([...messages, { text: inputValue }]);
      setInputValue('');
    }
  };

  return (
    

      

        {messages.map((message, index) => (
          
{message.text}
        ))}
      
      
         setInputValue(e.target.value)}
        />
        Send
      
    
  );
};

export default ChatInterface;`}
        
    

Connecting to Supabase

Create a new file called supabase.js in the lib folder and add the following code:

        {`import { createClient } from '@supabase/supabase-js';

export const supabase = createClient(
  'your_supabase_url',
  'your_supabase_key'
);`}
        
    

State management with Jotai

In your main _app.js file, you’ll need to wrap your app with the Jotai provider. Here’s how you can do it:

        {`import { Provider } from 'jotai';
import '../styles/globals.css';

function MyApp({ Component, pageProps }) {
  return (
    
      
    
  );
}

export default MyApp;`}
        
    

Conclusion

By following this tutorial, you should now have a basic chat interface that allows users to send and receive messages. You can further improve this by integrating ChatGPT or other language models to generate responses based on user input. Have fun building your chatbot clone and exploring the possibilities of Next.js, Supabase, and Jotai!
