A Jupyter Lab extension for itables

This extension exposes the jquery and datatables.net libraries and css as static files in Jupyter Lab.

The purpose of doing this is to allow the itables package to have an offline mode in Jupyter Lab.

Install it in the Python environment you use to launch Jupyter Lab with:

pip install jupyterlab-itables

Then relaunch Jupyter Lab with

jupyter lab

Assuming that Jupyter Lab is running on port 8888, you will be able to access the static files at e.g.

• http://localhost:8888/static/itables/jquery/dist/jquery.min.js
• http://localhost:8888/static/itables/datatables.net-dt/css/jquery.dataTables.min.css
• http://localhost:8888/static/itables/datatables.net/js/jquery.dataTables.mjs

How to develop this extension

Assuming that you have conda and mamba, you can create a minimal Jupyter Lab environment with

mamba env create --file environment.yml

or update it with

mamba env update --file environment.yml

Activate that environment with

conda activate jupyterlab-itables-dev

Then build the extension in development mode with

pip install -ve .

In development mode the extension needs to be enabled manually with:

jupyter server extension enable --py jupyterlab_itables

How to release a new version manually

Clean the project files with

rm -rf node_modules jupyterlab_itables/static dist build package-lock.json

Upgrade the version number in setup.py, then:

python setup.py sdist bdist_wheel

Check the size and the contents of the .tar.gz file in the dist folder, and then upload it to pypi with

twine upload dist/jupyterlab-itables-xxx.tar.gz
