Github Actions StatusBinder


This extension is composed of a Python package named jupyterlab_publishweb for the server extension and a NPM package named jupyterlab-publishweb for the frontend extension.


  • JupyterLab >= 2.0


Note: You will need NodeJS to install the extension.

pip install jupyterlab_publishweb
jupyter lab build


If you are seeing the frontend extension but it is not working, check that the server extension is enabled:

jupyter serverextension list

If the server extension is installed and enabled but you are not seeing the frontend, check the frontend is installed:

jupyter labextension list

If it is installed, try:

jupyter lab clean
jupyter lab build



The jlpm command is JupyterLab's pinned version of yarn that is installed with JupyterLab. You may use yarn or npm in lieu of jlpm below.

# Clone the repo to your local environment
# Move to jupyterlab-publishweb directory

# Install server extension
pip install -e .
# Register server extension
jupyter serverextension enable --py jupyterlab_publishweb --sys-prefix

# Install dependencies
# Build Typescript source
jlpm build
# Link your development version of the extension with JupyterLab
jupyter labextension install .
# Rebuild Typescript source after making changes
jlpm build
# Rebuild JupyterLab after making any changes
jupyter lab build

You can watch the source directory and run JupyterLab in watch mode to watch for changes in the extension's source and automatically rebuild the extension and application.

# Watch the source directory in another terminal tab
jlpm watch
# Run jupyterlab in watch mode in one terminal tab
jupyter lab --watch

Now every change will be built locally and bundled into JupyterLab. Be sure to refresh your browser page after saving file changes to reload the extension (note: you'll need to wait for webpack to finish, which can take 10s+ at times).


pip uninstall jupyterlab_publishweb
jupyter labextension uninstall jupyterlab-publishweb
