Darkside ui and syntax theme for JupyterLab



  • JupyterLab >= 3.0


NOTE: After installing and launching jupyter lab, the theme still needs to be enabled:
Settings > JupyterLab Theme > @dunovank/jupyterlab_darkside_ui

pip install jupyterlab_darkside_ui


pip uninstall jupyterlab_darkside_ui
jupyter labextension uninstall @dunovank/jupyterlab_darkside_ui


  • You can watch the source directory and run JupyterLab at the same time in different terminals to watch for changes in the extension’s source and automatically rebuild the extension.

  • 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.

  • With the watch command running, every saved change will immediately be built locally and available in your running JupyterLab. Refresh JupyterLab to load the change in your browser (you may need to wait several seconds for the extension to be rebuilt).

  • By default, the jlpm run build command (see above) generates the source maps for this extension to make it easier to debug using the browser dev tools. To also generate source maps for the JupyterLab core extensions, you can run the following command:

Build & Watch (Terminal 1)

# Clone the repo to your local environment
# cd to the jupyterlab_darkside_ui dir
# Install package in editable (-e) mode
pip install -e .

# Link your dev version of
# the extension with JupyterLab
jupyter labextension develop . --overwrite

# Rebuild extension Typescript
# source after making changes
jlpm run build

# Watch the source
# dir in Terminal 1
jlpm run watch

Run JupyterLab (Terminal 2)

jupyter lab


pip install jupyter_packaging twine
python setup.py sdist bdist_wheel && twine upload dist/*
jlpm build:lib && npm publish --access public
