hatch-jupyter-builder
A hatch plugin to help build Jupyter packages
Decision gist · record as of 2026-08-14
Yes, if you are building Jupyter packages with Hatch and need to automate custom build steps. The low install friction and permissive license make it straightforward to adopt. However, note the dormant maintenance status—no releases for 885 days—so verify compatibility with your current Hatch and Jupyter versions before relying on it for new projects. It is most suitable for teams already committed to Hatch or migrating from jupyter-packaging.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Hatch as the build system and Python >= 3.8; the hook only activates when configured in a Hatch project's pyproject.toml.
- Low friction installation with a single runtime dependency on hatchling.
- The project is dormant (last commit 2024-06-16, no release for 885 days), but remains available and functional for existing Jupyter packaging workflows.

What it is and what it does
hatch-jupyter-builder is a Hatch build hook that integrates custom build steps into the Jupyter package creation workflow. It acts as a bridge between Hatch's build system and Jupyter-specific compilation tasks—such as building frontend assets or running custom build scripts—that need to run before the final package is assembled. The plugin is designed for maintainers migrating from setuptools and jupyter-packaging to Hatch, and includes a migration utility to help convert existing configurations.
When configured in a project's pyproject.toml, the hook intercepts the build process and executes Jupyter-specific build steps automatically. It can be skipped via the SKIP_JUPYTER_BUILDER environment variable for development workflows. The package is maintained by the Jupyter project and supports Python 3.8 and later, including both CPython and PyPy implementations.
Use it for
- Building JupyterLab extensions or plugins that require frontend asset compilation before packaging.
- Migrating an existing setuptools-based Jupyter package to Hatch with minimal configuration changes.
- Automating custom build steps (e.g., TypeScript compilation, webpack bundling) as part of the Hatch build pipeline.
- Comparing distribution artifacts when migrating from jupyter-packaging to verify build output consistency.
- Skipping build steps in development environments while keeping them active in CI/release builds.
