uv supports two templates for projects:

• Applications uv init proj_name: for web servers, scripts, and command-line interfaces.

• Libraries uv init --lib proj_name: intended to be built and distributed (e.g., uploaded to PyPI).

Install local pyproject.toml in editable mode with dev dependencies: uv pip install -e .

Activate the virtual environment:

• Windows (cmd): .venv\Scripts\activate

• Windows (PowerShell): .\.venv\Scripts\Activate.ps1

• macOS/Linux: source .venv/bin/activate

Optional dependencies ([project.optional-dependencies]) are extras that get published and can be installed via pip install package[extra].

• Install a single extra: uv pip install -r pyproject.toml --extra dev

• Install all extras: uv pip install -r pyproject.toml --all-extras

Dependency groups ([dependency-groups]) are development-only groups (tests, linters, build tools, etc.) that do not get published to PyPI.

• Install a single dependency-group: uv pip install --group dev

• Install all dependency-groups: uv pip install --all-groups
