Architecture Philosophy
Vision
Clean Stack emerges from real-world challenges in modern software development. Our vision is to provide a robust foundation that eliminates common technical hurdles while maintaining flexibility for diverse business needs.
Core Principles
1. Developer Experience First
- Productivity Focus: Tools and patterns chosen to maximize developer efficiency
- Type Safety: End-to-end TypeScript for better code reliability
- Clear Conventions: Standardized practices to reduce decision fatigue
- Great Documentation: Comprehensive guides and API documentation
2. Domain-Driven Design
- Clear Boundaries: Business logic isolated in domain layer
- Pure Core: Domain logic free from technical concerns
- Shared Understanding: Common language between technical and business teams
- Flexible Evolution: Easy adaptation to changing business needs
3. Clean Architecture
- Independent Core: Business logic independent of frameworks
- Dependency Inversion: External concerns depend on core, not vice versa
- Clear Interfaces: Well-defined boundaries between layers
- Testable Design: Easy to test each layer in isolation
4. Microservices Done Right
- Smart Endpoints: Services contain business logic
- Dumb Pipes: Simple, reliable communication via gRPC
- Independent Deployment: Services can be deployed independently
- Resilient Design: Fault isolation and graceful degradation
5. Observable by Default
- Distributed Tracing: Track requests across services
- Metrics Collection: Monitor system health and performance
- Structured Logging: Consistent logging across services
- Performance Insights: Built-in tools for performance analysis
6. Production Ready
- Security First: Built-in security best practices
- Scalable Architecture: Designed for horizontal scaling
- Performance Optimized: Efficient resource usage
- Maintainable Code: Clear structure and conventions
Implementation Philosophy
Technology Choices
Each technology is chosen with clear purpose:
| Choice | Rationale |
|---|---|
| Bun | Modern, fast, compatible package management |
| Koa | Lightweight, modern HTTP server framework |
| gRPC | Efficient, type-safe service communication |
| OpenTelemetry | Industry standard observability |
| NX | Powerful monorepo management |
Error Handling
- Custom Error Types: Domain-specific error handling
- Consistent Patterns: Standard error handling across services
- Clear Communication: User-friendly error messages
- Proper Logging: Error tracking and debugging support
Testing Strategy
- Unit Testing: Core business logic
- Integration Testing: Service interactions
- E2E Testing: Critical user paths
- Performance Testing: Load and stress tests
