Common utilities for jupyter-contrib projects.
Decision gist · record as of 2026-08-14
Yes, if you are developing jupyter-contrib extensions or need version-agnostic nbextension APIs. No, if you are an end user—this is a library for extension developers. Conditional: verify compatibility with your Jupyter notebook version before installing, as the last release predates recent notebook versions.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a compatible Jupyter notebook installation; version compatibility issues may arise depending on your notebook version.
- High install friction with no runtime dependencies.
- Last release was 2022-11-15, though the repository remains active with recent commits.

What it is and what it does
jupyter-contrib-core is a shared library for the jupyter-contrib ecosystem, providing compatibility utilities and common components used by multiple Jupyter notebook extensions. It bridges API differences across Jupyter notebook versions (particularly 4.0, 4.1, and 4.2), offers command-line application scaffolding, and includes testing utilities for extension developers.
The package is primarily a dependency for other jupyter-contrib projects rather than a direct end-user tool. It has no runtime dependencies and is designed to be lightweight, but carries high install friction. With no releases since 2022-11-15 and a repository showing recent activity, it may face compatibility issues with newer Jupyter versions.
Use it for
- Developing Jupyter notebook extensions that need to support multiple notebook versions
- Building jupyter-contrib ecosystem projects that share common utilities and CLI scaffolding
- Writing tests for Jupyter extensions using the provided testing utilities and environment helpers
- Accessing the nbextension API in a version-agnostic way across notebook 4.0, 4.1, and 4.2
