Overview

JupyterLite

ci-badge binder-badge docs-badge

JupyterLite is a JupyterLab distribution that runs entirely in the browser built from the ground-up using JupyterLab components and extensions.

⚡ Status ⚡

Although JupyterLite is currently being developed by core Jupyter developers, the project is still unofficial.

Not all the usual features available in JupyterLab and the Classic Notebook will work with JupyterLite, but many already do!

Don't hesitate to check out the documentation for more information and project updates.

✨ Try it in your browser ✨

JupyterLite works with both JupyterLab and RetroLab.

Try it with JupyterLab! Try it with RetroLab!

🏗️ Build your own JupyterLite 🏗️

Install jupyterlite from PyPI, which comes with the CLI and a pre-built, empty site archive.

python -m pip install --pre jupyterlite

Use the jupyter lite CLI to build, check, or create a reproducible, remixable archive of your site, then publish your built site to any static host, such as GitHub Pages or ReadTheDocs.

jupyter lite description extras
init build an empty site from the bundled app archive
build add your own notebooks, labextensions, and settings jupyter_server for indexing content
serve try out your site locally tornado for snappier serving
check check your site's metadata jsonschema for schema validation
archive create a single-file archive

Features

For more details, see the JupyterLite documentation.

Browser-based Interactive Computing

  • Python kernel backed by Pyodide running in a Web Worker
    • Initial support for interactive visualization libraries such as altair, bqplot, ipywidgets, matplotlib, and plotly
  • JavaScript and P5.js kernels running in an IFrame
  • View hosted example Notebooks and other files, then edit, save, and download from the browser's IndexDB (or localStorage)
  • Support for saving settings for JupyterLab/Lite core and federated extensions
  • Basic session and kernel management to have multiple kernels running at the same time
  • Support for Code Consoles

Ease of Deployment

  • Served via well-cacheable, static HTTP(S), locally or on most static web hosts
  • Embeddable within larger applications
  • Requires no dedicated application server much less a container orchestrator
  • Fine-grained configurability of page settings, including reuse of federated extensions

JupyterLite is a reboot of several attempts at making a full static Jupyter distribution that runs in the browser, without having to start the Python Jupyter Server on the host machine.

The goal is to provide a lightweight computing environment accessible in a matter of seconds with a single click, in a web browser and without having to install anything.

This project is a collection of packages that can be remixed together in variety of ways to create new applications and distributions. Most of the packages in this repo focus on providing server-like components that run in the browser (to manage kernels, files and settings), so existing JupyterLab extensions and plugins can be reused out of the box.

    This PR implements a DriveFS custom file system which allows Emscripten kernels to have access to JupyterLab files. It uses a service worker to make any async task of accessing/deleting/renaming files into a synchronous task.

    User-facing changes

    • for GUI users
      • might be slightly faster, as it would save ~5 requests to pypi.org... but not really until more stuff is indexed
      • if fully cached, dependencies that change "in the wild" will not impact users of an already-built site, leading to less breakage a la #311
    • for CLI users
      • eventually should be able to
        • point to alternate PyPI indexes, mirrors
        • easily include additional, pre-cached packages

       except Exception as err:  # pragma: no cover

    It could be convenient if this was an exception instead, I've seen cases where the xeus-python addon would fail to load and it would have been convenient for jupyter lite build to not continue building.

    Proposed Solution

    Some options:

    • check the strict mode (True by default) and fail on any entry_point.load()
      • maybe still try to .load() all of them, and collect and print all the errors together
        • getting all of the tracebacks is often useful, though, too

  • Strange inconsistency with the file system

    Strange inconsistency with the file system

    Description

    I am playing around with JupyterLite, and I often end up facing a problem with the file system. It basically goes as follows:

    1. When opening for the first time an instance served by a static Github Page such as this one, if I enter the command pwd I get in return /drive. This is important because it means that Pyodide is able to "see" what is in the contents folder, and I can import local scripts.
    2. After a while playing with the repo, making some changes, something breaks. The command pwd returns /home/pyodide, and files in the browser become invisible to pyodide (I explored the filesystem with os and there is no drive folder to be found. This means that I cannot do anymore local imports.

    Reproduce

    I am sorry that I cannot yet point to what exactly I do wrong. I have a hard time reproducing consistently the issue, yet it happened twice to me.

    A few elements though:

    • if I open the webpage from a different browser there is no problem at all.
    • I usually install both pyodide and Xeus-python to compare them

    I hope this makes sense to someone.

  • Hoist the Python package to the top-level?

    Hoist the Python package to the top-level?

    Problem

    Currently the jupyterlite Python package is located under py/jupyterlite: https://github.com/jupyterlite/jupyterlite/tree/main/py/jupyterlite

    If I recall correctly this was mostly to accommodate the potential new Python packages that would be developed in the monorepo such as https://github.com/jupyterlite/jupyterlite/issues/165.

    Proposed Solution

    With the use of CLI addons and support for federated extensions, maybe there won't be any needs for new Python packages in the same jupyterlite repository.

    If we want to provide more Python packages, maybe they could live outside of the main repo but within the jupyterlite org on GitHub: https://github.com/jupyterlite

    Benefits for hoisting the Python package to the top-level would be:

    • a single pyproject.toml (the others in Pyolite will be moved to https://github.com/jupyterlite/pyodide-kernel with #854)
    • no need to sync the README.md
    • follow the same structure as many other Jupyter projects

    Additional context

    In https://github.com/jupyterlite/jupyterlite/pull/854 and some other issues there were also mentions of having a jupyterlite_core or jupyterliter, and make jupyterlite a metapackage to distribute JupyterLite with a set of pre-defined packages.

    Even if that was the case, maybe the jupyterlite metapackage could then also live outside in the main repo but still in https://github.com/jupyterlite.
