# DDNS Updater - Architecture Documentation
This directory contains comprehensive architecture documentation for the DDNS Updater project, including automatically generated diagrams from PlantUML sources.
## 📊 Architecture Diagrams
The following diagrams provide different views of the system architecture:

- External service dependencies (IP providers, DNS, web servers)
- File system interactions for configuration and storage
- Service factory pattern for dependency injection
### Clean Architecture Layers
![Clean Architecture](./images/clean-architecture.svg)
**Purpose**: Detailed view of the clean architecture implementation showing how dependency inversion is achieved through trait-based design.
**Key Features**:
- **Interface Layer**: CLI parsing and user interaction
- **Application Layer**: Use cases, service factory, and application configuration
- **Domain Layer**: Business entities, services, and ports (interfaces)
- **Infrastructure Layer**: Concrete implementations of domain ports
### Data Flow Diagram
![Data Flow](./images/data-flow.svg)
**Purpose**: Step-by-step sequence showing how a DDNS update request flows through the system from CLI input to completion.
**Key Features**:

- Error handling paths and recovery mechanisms
- External service interactions (IP providers, web servers)
- Data persistence and notification flows
### Component Interaction
![Component Interaction](./images/component-interaction.svg)
**Purpose**: Detailed component relationships showing how different parts of the system interact and depend on each other.

## 🔧 Diagram Generation
### Automatic Generation
Architecture diagrams are automatically generated using GitHub Actions whenever PlantUML source files are modified:
1. **Trigger**: Push to main branch or PR with changes to `docs/diagrams/*.puml`
2. **Process**: PlantUML GitHub Action generates SVG and PNG versions
3. **Output**: Generated diagrams are saved to `docs/images/`
4. **Commit**: Changes are automatically committed back to the repository
### Manual Generation
To generate diagrams locally:
```bash
# Install PlantUML
sudo apt-get install plantuml
# Generate all diagrams
plantuml -tsvg -o ../images docs/diagrams/*.puml
plantuml -tpng -o ../images docs/diagrams/*.puml
```
### Source Files
PlantUML source files are located in `docs/diagrams/`:
- `system-architecture.puml` - Overall system architecture
- `clean-architecture.puml` - Clean architecture layers and dependencies
- `data-flow.puml` - Data flow and sequence diagrams
- `component-interaction.puml` - Component relationships and interactions
- `state-diagram.puml` - State machine and process flow
- `deployment.puml` - Deployment and infrastructure architecture
## 📝 Architecture Decisions
### Clean Architecture Implementation
The DDNS updater follows clean architecture principles:
1. **Dependency Inversion**: All dependencies flow inward toward the domain layer
2. **Trait-Based Design**: Interfaces (ports) defined as Rust traits
3. **Separation of Concerns**: Each layer has distinct responsibilities
4. **Testability**: Each component can be tested in isolation
### Multi-Web Server Support
The system is designed to support multiple web servers through a common interface:
-**Nginx**: Complete implementation with location block handling
-**Apache**: Complete implementation with Directory/Location blocks
- 🔲 **Caddy**: Framework ready for implementation
- 🔲 **Traefik**: Framework ready for implementation
### Async Architecture
Full async/await support throughout:
- **Tokio Runtime**: Single-threaded async runtime for CLI application
- **Async Traits**: All service boundaries use async trait implementations
- **Thread Safety**: Send + Sync bounds for all shared components
- **Error Handling**: Comprehensive error types with async propagation
### Configuration Management
Flexible configuration discovery and validation:
- **Pattern Matching**: Support for glob patterns (*.conf, *.nginx, etc.)
- **Auto-Detection**: Automatic web server type detection from config content
- **Validation**: Configuration syntax validation before updates
- **Backup Management**: Automatic backup creation with configurable retention
## 🧪 Testing Architecture
The testing strategy aligns with the architectural layers:
### Unit Tests
- **Domain Layer**: Business logic validation
- **Infrastructure Layer**: Individual component testing
- **Application Layer**: Service factory and use case testing
### Integration Tests
- **CLI Interface**: End-to-end command line testing
- **File System**: Configuration file processing
- **Network Services**: IP provider integration (with CI-friendly mocking)
### Architecture Tests
- **Dependency Rules**: Ensure clean architecture boundaries are maintained
- **Trait Implementation**: Verify all ports have proper implementations
- **Error Handling**: Comprehensive error scenario coverage
## 🚀 CI/CD Integration
### GitHub Actions Workflows
1. **Diagram Generation**: Automatic PlantUML rendering on source changes
2. **Testing Pipeline**: Comprehensive test suite with CI environment detection
3. **Package Building**: Debian package generation for multiple architectures
4. **Documentation**: Automatic documentation updates
### Quality Assurance
- **Code Formatting**: Automatic rustfmt application
- **Linting**: Clippy analysis with architectural rule enforcement
- **Dependency Auditing**: Security vulnerability scanning
- **Performance Testing**: Benchmark regression detection
