A Node.js-Based WhatsApp and OpenAI Integration

🚀 Technology Stack:

Node.js (v20.5.0) WhatsApp Web.js OpenAI API

🔑 Features:

WhatsApp Integration:

Real-time QR code generation for easy login. Automated responses to incoming WhatsApp messages. Ability to send and receive images and text messages dynamically. OpenAI Enhanced Interactions: Integration with OpenAI's API to handle requests and generate content. Capable of generating images through DALL-E 2 based on text prompts received via WhatsApp. Uses OpenAI's advanced GPT models to provide text-based answers for queries.

🔧 Core Functionality:

This system uses dotenv for environment management and node-fetch for HTTP requests. A special mechanism fetches the latest WhatsApp web version to ensure compatibility. The script is set to recognize commands prefixed with "#", processes them, and utilizes OpenAI's capability to respond with either an image or a text message, based on the command context.

📈 Use Case:

This integration is ideal for automating responses in customer service, providing educational content, or even just for fun interactive bots on WhatsApp that can visualize topics or explain complex information through intuitive AI-generated content.

Running the Server

Start the Node server: bash Copy code node index.js

This command runs the server locally and generates a QR code for WhatsApp Web integration. Scan this QR code with your WhatsApp mobile app to start receiving and responding to messages. Usage: Users should send messages prefixed with a pound sign # to trigger the GPT model responses. Based on the user's request, the server can provide textual responses or relevant images.
