Code sharing¶
Share re-usable code in dedicated repositories on DHI GitHub.
Recommendations¶
Below are some recommendations on tools and practices related to developing software in Python at DHI.
- I use Git for source control
- I prefer VS Code as IDE
- I use pyproject.toml for project configuration over setup.py
- I document dependencies and pin the versions when developing applications to ensure reproducibility.
- I use pytest for testing
- I use ruff for linting and formatting
- I add type hints to all public methods
- I document my public API
- I use NumPy style docstrings
- I automate tests and quality checks with CI (GitHub Actions / Azure Devops Pipelines)
- I include a license (I prefer MIT for open-source projects)
- I use virtual environments (e.g., venv) for isolated development
- I use Snyk for automated code and dependency vulnerability scanning
- I maintain a README.md with instructions targeted to developers
- I participate in code reviews and prefer pull requests over direct commits to main branches
