Major refactor from simple HTML/JS app to modern full-stack TypeScript application: ## Architecture Changes - Migrated to monorepo structure with workspaces (backend, frontend, shared) - Backend: Node.js + Express + TypeScript + Socket.IO - Frontend: Next.js 15.5 + React 19 + TypeScript + Tailwind CSS - Shared: Common types and utilities across packages ## Key Features Implemented - Real-time WebSocket collaboration via Socket.IO - Virtual canvas with chunked loading for performance - Modern UI with dark mode and responsive design - Mock database system for easy development (Redis/PostgreSQL compatible) - Comprehensive error handling and rate limiting - User presence and cursor tracking - Infinite canvas support with zoom/pan controls ## Performance Optimizations - Canvas virtualization - only renders visible viewport - Chunked pixel data loading (64x64 pixel chunks) - Optimized WebSocket protocol - Memory-efficient state management with Zustand ## Development Experience - Full TypeScript support across all packages - Hot reload for both frontend and backend - Docker support for production deployment - Comprehensive linting and formatting - Automated development server startup ## Fixed Issues - Corrected start script paths - Updated environment configuration - Fixed ESLint configuration issues - Ensured all dependencies are properly installed - Verified build process works correctly
