OpenAI API Integration with Express

This Node.js application integrates the OpenAI Assistant's API with an Express server. It allows users to interact with an OpenAI-powered chatbot through a RESTful API.

Features

• Integration with OpenAI API.
• Express server setup with middleware.
• Endpoint for chat interactions.

Prerequisites

• Node.js installed.
• An OpenAI API key.

Installation

1. Clone the Repository:

   git clone https://github.com/RaheesAhmed/Assistant-Api.git
   cd openai-express-app

2. Install Dependencies:

   npm install

3. Set Up Environment Variables: Create a .env file in the root directory and add your OpenAI API key:

   OPENAI_API_KEY=your_openai_api_key

Usage

1. Start the Server:

   npm start

2. Interact with the Chatbot: Send a POST request to /chat with a JSON payload:

   {
     "message": "Your query here"
   }

   You can use tools like Postman or a frontend interface to send the request.

3. View Responses: The server will respond with the chatbot's answer.

Notes

• The application uses body-parser for parsing incoming request bodies and morgan for HTTP request logging.
• CORS is enabled for cross-origin requests.
• The createAssistant function initializes a new OpenAI assistant with specific instructions and settings.
• All chat interactions are managed through the /chat endpoint.
