DustyWalker Date: Tue, 5 Aug 2025 17:02:03 +0200 Subject: [PATCH 11/32] feat(db): implement complete database schema and models MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add Prisma schema with PostgreSQL 15 support - Create Users, Batches, Images, Payments, ApiKeys tables - Implement proper foreign key relationships and indexes - Add enum types for status fields (Plan, BatchStatus, ImageStatus, PaymentStatus) - Support for JSON fields (vision_tags, metadata) - UUID primary keys for security - Created/updated timestamps with proper defaults Database Layer Components: - Prisma service with connection management and health checks - Repository pattern for all entities with comprehensive CRUD operations - TypeScript DTOs with class-validator decorations - Swagger API documentation annotations - Helper functions for business logic (quota management, pricing, etc.) Development Support: - Environment variables template - Database seed script with realistic test data - TypeScript configuration optimized for Nest.js - Package.json with all required dependencies Resolves database requirements from issues §78-81 establishing the complete data layer foundation for the AI Bulk Image Renamer SaaS. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- packages/api/.env.example | 51 ++

The implementation includes: ## Core Components Implemented: ### 1. Background Job Queue System ✅ - Progress tracking with Redis and WebSocket broadcasting - Intelligent retry handler with exponential backoff strategies - Automated cleanup service with scheduled maintenance - Queue-specific retry policies and failure handling ### 2. Security Integration ✅ - Complete ClamAV virus scanning service with real-time threats detection - File validation and quarantine system - Security incident logging and user flagging - Comprehensive threat signature management ### 3. Database Integration ✅ - Prisma-based database service with connection pooling - Image status tracking and batch management - Security incident recording and user flagging - Health checks and statistics collection ### 4. Monitoring & Observability ✅ - Prometheus metrics collection for all operations - Custom business metrics and performance tracking - Comprehensive health check endpoints (ready/live/detailed) - Resource usage monitoring and alerting ### 5. Production Docker Configuration ✅ - Multi-stage Docker build with Alpine Linux - ClamAV daemon integration and configuration - Security-hardened container with non-root user - Health checks and proper signal handling - Complete docker-compose setup with Redis, MinIO, Prometheus, Grafana ### 6. Configuration & Environment ✅ - Comprehensive environment validation with Joi - Redis integration for progress tracking and caching - Rate limiting and throttling configuration - Logging configuration with Winston and file rotation ## Technical Specifications Met: ✅ **Real AI Integration**: OpenAI GPT-4 Vision + Google Cloud Vision with fallbacks ✅ **Image Processing Pipeline**: Sharp integration with EXIF preservation ✅ **Storage Integration**: MinIO/S3 with temporary file management ✅ **Queue Processing**: BullMQ with Redis, retry logic, and progress tracking ✅ **Security Features**: ClamAV virus scanning with quarantine system ✅ **Monitoring**: Prometheus metrics, health checks, structured logging ✅ **Production Ready**: Docker, Kubernetes compatibility, environment validation ## Integration Points: - Connects with existing API queue system - Uses shared database models and authentication - Integrates with infrastructure components - Provides real-time progress updates via WebSocket This resolves the critical gap identified in the audit and provides a complete, production-ready worker service capable of processing images with real AI vision analysis at scale. 🤖

19:04:51 +0200 Subject: [PATCH 26/32] feat(frontend): implement Next.js frontend package foundation with complete API integration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit establishes the complete Next.js frontend foundation with comprehensive backend integration: ## Core Infrastructure ✅ - Next.js 14 with App Router and TypeScript configuration - Tailwind CSS with custom design system and dark mode - Complete project structure with proper imports and path aliases ## API Integration Layer ✅ - Full-featured API client with authentication, file upload, and WebSocket - Comprehensive TypeScript type definitions for all API responses - Axios-based HTTP client with interceptors and error handling - Socket.io integration for real-time progress updates ## Authentication System ✅ - useAuth hook with Google OAuth integration - JWT token management with automatic refresh - Protected route handling and session persistence - Login/logout flow with redirect management ## File Upload System ✅ - useUpload hook with drag & drop functionality - File validation (size, type, duplicates) - Progress tracking during upload - Batch creation and image processing workflow ## WebSocket Integration ✅ - useWebSocket hook for real-time updates - Progress subscription for batch processing - Reconnection logic with exponential backoff - Event-driven updates for batches, images, and user data ## UI Foundation ✅ - Responsive Header with user authentication state - Professional Footer with proper navigation - Error Boundary for graceful error handling - Toast notification system with multiple variants - Loading spinners and UI components ## Layout & Navigation ✅ - Main page component with authenticated/unauthenticated states - Dynamic content switching between landing and dashboard - Mobile-responsive design with proper accessibility This provides the complete foundation for a production-ready frontend that integrates seamlessly with the existing backend APIs, supporting all core workflows from authentication to file processing. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By:
