back end for ai chat

The project is a backend system for an AI-powered chat platform focused on frontend development assistance. It provides APIs that handle user messages, forward prompts to an AI model, and return intelligent, context-aware responses. The system manages conversation sessions, stores chat history, and ensures smooth real-time communication between the client and the AI engine. It is built with Node.js and Express, structured to deliver fast processing, secure data handling, and a clean integration point for the frontend interface.
