Prerequisites

Depending on the package manager chosen when the project was scaffolded, install the corresponding tool once on your machine before proceeding.

Package manager	Install
pixi (default)	curl -fsSL https://pixi.sh/install.sh | bash — pixi.sh
poetry	pipx install poetry — python-poetry.org
mamba	Miniforge

For Docker workflows you also need Docker.

Development setup

pixi

Pixi manages Python, all conda-forge and PyPI dependencies, and the virtual environment in a single tool. The environment lives at .pixi/envs/ and is not committed to git.

# Install all dependencies (creates the environment from pixi.lock)
pixi install

# Open a shell with dev tools available
pixi shell -e dev

# Or run a single task without activating the shell
pixi run -e dev test
pixi run -e dev lint
pixi run -e dev format
pixi run -e dev typecheck

Add a new dependency:

pixi add numpy                     # conda-forge, runtime
pixi add --pypi requests           # PyPI, runtime
pixi add --feature dev pytest-mock # dev-only

Update all dependencies and regenerate the lockfile:

pixi update
git add pixi.lock && git commit -m 'chore: update pixi lockfile'

---

poetry

Poetry manages PyPI dependencies and creates .venv/ inside the project root (configured in poetry.toml). Python itself comes from your system, pyenv, or a conda base environment — it must not be installed inside the project venv.

# One-time: install poetry globally, isolated from any project
pipx install poetry

# Inside the project folder — creates .venv/ and installs all deps
poetry install

# Activate the venv for an interactive session
poetry shell

# Or prefix individual commands
poetry run pytest tests/

Add a new dependency:

poetry add numpy                      # runtime → updates pyproject.toml + poetry.lock
poetry add --group dev pytest-mock    # dev-only

Update dependencies:

poetry update            # update all within declared constraints
poetry update numpy      # update a single package
git add poetry.lock && git commit -m 'chore: update poetry lockfile'

---

mamba / conda

Mamba manages both the virtual environment and the packages.

# Create a project-local environment
mamba env create -f environment.yaml -p .venv
mamba activate .venv/

# Install dev dependencies on top
mamba env update --prefix .venv --file environment.dev.yaml

# Recreate / update after environment files change
mamba env update --prefix .venv --file environment.yaml --prune

Add a new dependency: edit environment.yaml, then run mamba env update --prune.

Common development tasks

All tasks are available via make. Run make with no arguments to execute lock → build-image → run-local.

Command	What it does
make test	Run the test suite
make lint	Lint with ruff
make format	Auto-format with ruff
make typecheck	Type-check with mypy
make lock	Update the dependency lockfile
make build-image	Build the Docker image
make push-registry	Push the image to the container registry
make run-local	Start the app locally via docker-compose
make build-docs	Build the Jupyter Book documentation
make clean-docs	Remove the documentation build output

---

Pre-commit hooks

Code quality checks run automatically on every git commit. Install the hooks once after cloning:

pre-commit install

Run all hooks manually at any time:

pre-commit run --all-files

The hooks cover: ruff (lint + auto-fix), ruff-format, mypy, and standard file hygiene (trailing whitespace, YAML validity, merge-conflict markers, large files).

---

Docker

Copy .env.example to .env and fill in the values (copier does this automatically on first scaffold):

cp .env.example .env

Command	What it does
make build-image	Builds ${CONTAINER_REGISTRY}/analytics/${IMAGE_NAME}:${IMAGE_TAG}
make run-local	Runs the image via docker-compose-dev.yaml
make push-registry	Pushes to the container registry

Key Docker files:

File	Purpose
Dockerfile	Multi-stage build (adapts to the chosen package manager)
docker-compose-build.yaml	CI/CD image build
docker-compose-dev.yaml	Local dev/test run with secrets and env vars
docker-compose.yaml	Production deployment spec

VS Code setup

Recommended extensions (install via the Extensions panel or .vscode/extensions.json):

Extension	Purpose
ms-python.python + ms-python.pylance	Python language support
charliermarsh.ruff	Linting and formatting (replaces black + isort)
ms-python.mypy-type-checker	Type checking

Formatting on save and import sorting are pre-configured in .vscode/settings.json.

Updating the template

To pull in improvements from the project template into this project:

copier update . --trust

Copier merges template changes with your local edits. Review the diff carefully before committing.
