This is a React-based application that leverages the power of OpenAI's ChatGPT API to generate human-like responses in a chat interface. This README.md will guide you through the setup and usage of this app. The Express server serves as a proxy to communicate with the ChatGPT API using gpt-turbo, as openai package has trouble using the gpt-3.5-turbo model.

To set up the project on your local machine, follow these steps:

1. Clone the repository:

git clone https://github.com/yourusername/chatgpt-react-express-app.git

2. Change to the project directory:

cd chatgpt-react-express-app

3. Install the dependencies:

npm install

4. Create a .env file in the root directory and add your OpenAI API key:

REACT_APP_OPENAI_API_KEY=your_openai_api_key

5. This application uses separate processes for the front-end and back-end. You can run them individually or concurrently using the following npm scripts:

Run the back-end server only:

npm run server

Run the front-end React development server only:

npm run client

Run both the back-end and front-end servers concurrently:

npm run dev

The application will now be running on http:https://localhost:3000. Open your browser and navigate to this address to start using the app.

1. Type your message in the input field at the bottom of the chat interface.
2. Press Enter or click on the Send button to submit your message.
3. The application will send the message to the ChatGPT API and display the generated response in the chat window.
4. You can continue the conversation by sending more messages. The chat history will be visible, allowing for a more engaging and interactive conversation.
