Submit ballet modules from within JupyterLab

Project description

Github Actions Status PyPI Shield npm version


Submit ballet modules from within JupyterLab

This extension is composed of a Python package named ballet-submit-labextension for the server extension and a NPM package also named ballet-submit-labextension for the frontend extension.


  • JupyterLab >= 2.0


Installation can be done completely using pip, which installs both the server and the frontend extensions. The frontend extension only can be installed using jupyter labextension install but will not function properly without the corresponding server extension.

pip install ballet-submit-labextension
jupyter lab build

Note: You will need NodeJS to install the extension; the installation process will complain if it is not found.

Authenticate with GitHub

The extension provides an in-lab experience for authenticating with GitHub. When you open a notebook, you should see the GitHub icon to the right on the Notebook toolbar. The icon should be grey at first, indicating you are not authenticated. Click the icon to open a login window, in which you can enter your GitHub username and password. These will be exchanged by the extension for an OAuth token and will be used to propose changes to the upstream Ballet project on your behalf (if you attempt to submit features).

Alternately, you can provide a personal access token directly using the configuration approaches below.


The extension ties into the same configuration system as Jupyter [Lab] itself. You can configure the extension with command line arguments or via the config file, just like you configure Jupyter Notebook or Jupyter Lab.

All configuration options

The following configuration options are available:

$ python -c 'from import print_help;print_help()'

BalletApp options
    Default: 60
    timeout to receive access token from server via polling
    Default: ''
    path to ballet.yml file of Ballet project (if Lab is not run from project
    Default: False
    enable debug mode (no changes made on GitHub), will read from $BALLET_DEBUG
    if present
    Default: ''
    github access token, will read from $GITHUB_TOKEN if present
    Default: ''
    url to github-oauth-gateway server

Command line arguments

Invoke Jupyter Lab with command line arguments providing config to the ballet extension, for example:

jupyter lab --BalletApp.debug=True

Config file

  1. Determine the path to your jupyter config file (you may have to create it if it does not exist):

    touch "$(jupyter --config-dir)/"
  2. Append desired config to the end of the file, for example:

    c.BalletApp.debug = True


If you are see 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 your not seeing the frontend, check the frontend is installed:

jupyter labextension list

If it is installed, try:

jupyter lab clean
jupyter lab build


Development Install

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 ballet-submit-labextension directory
# Install server extension
pip install -e .
# Register server extension
jupyter serverextension enable --py ballet-submit-labextension
# Install dependencies
# Build Typescript source
jlpm build
# Link your development version of the extension with JupyterLab
jupyter labextension link .

# 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


pip uninstall ballet-submit-labextension
jupyter labextension uninstall ballet-submit-labextension
