This plugin freezes the dependency tree of your builds. In practice, this ensures that Pip always pulls the exact same dependency tree when your package is installed.

In your pyproject.toml file, add the following:

[tool.hatch.build.hooks.frozen]
dependencies = ["hatch-frozen"]

The plug-in reads the frozen dependencies from the requirements.txt file of your project, so make sure this file exists.

1. Configure the pyproject.toml file as explained above.

2. Generate the requirements.txt file:

$ uv pip compile pyproject.toml -o requirements.txt

3. Build your package:

$ uv build

4. Clean the requirements file:

$ rm requirements.txt

The project uses uv as the package manager.

To run the tests, use:

uv run pytest

To verify the code style, use:

uvx ruff check

To release a new version of the package, bump the version in pyproject.toml and create and push a new git tag.
