What it is and what it does
jupyterlite-core is the foundation package for JupyterLite, a system that packages Jupyter environments to run entirely in a web browser without a backend server. It provides the CLI tool (jupyter-lite) and the build infrastructure needed to create and deploy JupyterLite websites, along with extension points for custom addons. The package depends on doit (a task automation tool), jupyter-core (Jupyter's base utilities), and pycparser (a C parser for handling low-level dependencies).
This is primarily a build-time and deployment tool for developers and site maintainers who want to create browser-based Jupyter environments. It's not a runtime library for end users of Jupyter notebooks, but rather the toolchain that powers the creation of such environments.
Use it for
- Build and deploy a JupyterLite website that runs Jupyter notebooks in the browser without a server.
- Create custom JupyterLite addons and extensions using the documented extension points.
- Automate the build process for browser-based Jupyter environments using the jupyter-lite CLI.
- Package Python environments with Pyodide to run scientific code directly in the browser.
- Host interactive documentation or educational materials as a serverless Jupyter interface.
