# Implement Service-Oriented Architecture for plantuml-python > Refactor procedural code into reusable service classes for better separation of concerns ## Objectives - Create DockerService to encapsulate all Docker-related operations - Create PlantumlService to handle diagram rendering logic - Decouple CLI from infrastructure concerns - Maintain backward compatibility with existing CLI interface ## Contexts - plantuml_renderer.py: Contains current procedural implementation - pyproject.toml: Project configuration file ## Low-level Tasks 1. CREATE services/docker_service.py: - Implement DockerService class with methods: - check_install() - start_server() - is_running() - wait_until_ready() - Add type hints and docstrings 2. CREATE services/plantuml_service.py: - Implement PlantumlService class with methods: - render_diagram(input, output) - generate_diagram_code() - Move rendering logic from main() 3. UPDATE plantuml_renderer.py: - Remove Docker-related logic - Remove rendering logic - Add service class imports - Refactor main() to use service instances 4. UPDATE cli.py: - Update CLI entrypoint to use service classes - Maintain existing command-line interface 5. UPDATE utils.py: - Move utility functions to appropriate service classes - Remove unused helper methods ## Dependencies - Use dependency injection for service instances in main() - Maintain single entrypoint in cli.py ## Validation - Existing CLI functionality must remain unchanged - Unit tests should be updated to test services in isolation
