Hatch Dependency Freezing Plugin: Enhancing Build Consistency

Streamline your Python packaging workflow with this Hatch plugin designed to freeze your project's dependency tree. By automatically resolving and pinning all direct and transitive dependencies into a manifest file during the build process, it ensures:

• Reproducible Builds: Guarantee that your package builds with the same dependency versions every time.
• Consistent Environments: Simplify the creation of identical environments across development, testing, and production.
• Dependency Transparency: Provides a clear, version-locked list of all project dependencies.

Configuration

Calling the plugin

Modify pyproject.toml to include the plugin as a build dependency:

[build-system]
requires = ["hatchling", "hatch-build-freeze"]
build-backend = "hatchling.build"

[tool.hatch.build.hooks.hatch-build-freeze]

Disable the plugin

By default, the plugin is enabled. To disable it, use the environment variable HATCH_BUILD_FREEZE_DISABLED

HATCH_BUILD_FREEZE_DISABLED=1 hatch build

Plugin Configuration

The following options are supported:

• groups (optional, list of strings): Specifies a list of dependency groups (e.g., from [dependency-groups]) to include in the frozen requirements.

  [tool.hatch.build.hooks.hatch-build-freeze]
  groups = ["group1", "group2"]
  

• extras (optional, list of strings): Specifies a list of optional dependency groups (e.g., from [project.optional-dependencies]) to include in the frozen requirements.

  [tool.hatch.build.hooks.hatch-build-freeze]
  extras = ["extra1", "extra2"]
  

• uv-args (optional, list of strings): A list of additional command-line arguments to pass directly to the uv export command.

  [tool.hatch.build.hooks.hatch-build-freeze]
  uv-args = ["--resolution=lowest-direct", "--no-header", "--prerelease=allow"]
