🔧 Development

Setting up Development Environment

1. Quick setup (recommended):

git clone <repository-url>
cd unitforge
make setup-dev  # Uses uv for fast setup

2. Manual setup:

git clone <repository-url>
cd unitforge
uv venv
source .venv/bin/activate
uv pip install -e ".[dev,web]"

3. Development workflow:

# Start development server
make server

# Run tests with coverage
make test-cov

# Format and lint code
make format && make lint

# Complete development cycle
make dev  # format + lint + test

# Use development helper
./dev.sh server    # Start server
./dev.sh test      # Run tests
./dev.sh format    # Format code

Adding New Templates

1. Create a new template class in backend/app/core/templates.py
2. Inherit from UnitTemplate
3. Define parameters and generation logic
4. Register in TemplateRegistry

Example:

class MyCustomTemplate(UnitTemplate):
    def __init__(self):
        super().__init__(
            name="my-template",
            description="My custom service template",
            unit_type=UnitType.SERVICE,
            category="Custom Services",
            parameters=[
                TemplateParameter("name", "Service name", "string"),
                # ... more parameters
            ]
        )

    def generate(self, params):
        # Implementation
        pass

Development Tools

Quality Assurance:

make lint          # Run all linters (black, isort, flake8)
make type-check    # Run mypy type checking
make security-check # Run bandit security scan
make pre-commit    # Run pre-commit hooks

Package Management:

make deps-update   # Update all dependencies
make deps-check    # Check for vulnerabilities
uv pip list        # List installed packages
uv pip show <pkg>  # Show package info

Docker Development:

make docker-build  # Build all images
make docker-dev    # Start dev environment
make docker-test   # Run tests in container
make docker-clean  # Clean up containers

Code Style

• Python: Follow PEP 8, use type hints, formatted with Black
• JavaScript: ES6+, consistent formatting
• HTML/CSS: Semantic markup, responsive design
• Pre-commit hooks: Automatic formatting and linting

🐳 Docker Support

UnitForge includes templates for containerized services:

# Docker service
./unitforge-cli template generate container \
  --param container_runtime=docker \
  --param image=myapp:latest

# Podman service
./unitforge-cli template generate container \
  --param container_runtime=podman \
  --param image=registry.example.com/myapp:v1.0
