NineStack – .NET 9 Clean Architecture Kit (CQRS , Auth ,Docker, .... )

Project Features Implemented:

✅ Clean Architecture - Organized into Domain, Application, Infrastructure, and WebApi layers
✅ CQRS Pattern - Command Query Responsibility Segregation with MediatR
✅ Architecture Testing - Unit tests for domain entities, value objects, and application handlers
✅ FluentValidation - Input validation for commands and queries
✅ Email Integration - Email service with SMTP support
✅ JWT Authentication & Authorization - Secure token-based authentication
✅ Unit of Work Pattern - Transaction management and repository coordination
✅ Middleware - Custom error handling and rate limiting middleware
✅ Entity Framework Core - Database access with code-first approach
✅ Polly - Resilience and transient-fault handling for HTTP clients
✅ Unit Testing - Comprehensive test coverage with xUnit, FluentAssertions, and Moq
✅ Docker Support - Dockerfile and docker-compose for containerization
✅ Specification Pattern - Domain specifications for complex queries
✅ Redis Cache - Distributed caching support (with in-memory fallback)
✅ Message Queue - RabbitMQ integration (with in-memory implementation)
✅ Generic Repository - Reusable repository pattern with specifications
✅ Rate Limiting - Request throttling middleware
✅ Background Jobs - Hangfire integration for background processing
✅ Logging System - Structured logging with console output
