Hatchling metadata hook to generate all extras
Decision gist · record as of 2026-08-14
Yes, if you use hatchling and want to offer an `all` extra without manual maintenance. The package is actively maintained, has no known vulnerabilities, and low install friction. It is in beta (Development Status :: 4), so expect the API to change before a 1.0.0 release—pin the version in your build-system.requires if stability is critical.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires at least one dynamic field in [project] metadata for Hatchling metadata hooks to trigger.
- Hatchling >= 1.18.0 required.
- Low install friction with a single runtime dependency on hatchling.

Alternatives
Verify before relying
Add to pyproject.toml:
[build-system]
requires = ["hatchling>=1.18.0", "hatchling-autoextras-hook"]
build-backend = "hatchling.build"
[tool.hatch.metadata.hooks.autoextras]
Then define optional dependencies and install with the generated `all` extra.- Whether the hook works correctly with all Hatchling versions in the >=1.18,<2.0 range or if specific minor versions have known issues.
- Real-world performance impact on build times for projects with many extras.
- Compatibility with Hatchling's other metadata hooks beyond the stated claim that they run in order.
What it is and what it does
hatchling-autoextras-hook is a build-time plugin for hatchling that intercepts your project's metadata during packaging and automatically creates an `all` extra that merges every optional dependency you've defined. It deduplicates and alphabetizes the combined list, so users can install the entire optional feature set with a single command.
The hook runs only during the build process and does not modify your source files or pyproject.toml. It requires hatchling as its sole runtime dependency and works with Python 3.10 or later. Configuration is minimal—just add the hook declaration to your pyproject.toml and ensure you have at least one dynamic field so hatchling's metadata system will invoke it.
Use it for
- Simplify installation for users who want all optional features without listing each extra separately.
- Maintain a single source of truth for optional dependencies while automatically exposing a convenience `all` extra.
- Reduce boilerplate in CI/CD pipelines by using a single `all` extra instead of enumerating multiple extras.
- Ensure consistency across multiple packages by centralizing the `all` extra generation logic.
- Avoid manual maintenance of an `all` extra that can become stale when new optional dependencies are added.
