jl-renku

A JupyterLab extension for Renku.

This extension is composed of a Python package named jl_renku for the server extension and a NPM package named jl-renku for the frontend extension.

Requirements

• JupyterLab >= 3.0

Install

To install from pypi, run the following command (this will fail at the moment, since jl_renku has not been published to pypi yet):

pip install jl_renku

If you have NodeJS available, you can also install from the repo:

pip install .

Troubleshoot

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

jupyter server extension list

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

jupyter labextension list

Contributing

Development install

Note: You will need NodeJS to build the extension package.

Create environment for development (optional)

If you have not already done so, you will probably want to set up an environment for developing the extension. Detailed instructions are in the JupyterLab Extension Tutorial.

Here are the key commands (assuming conda is installed) to create a conda environment that includes all prerequisites and the development version of JupyterLab:

conda create -n jupyterlab-ext --override-channels --strict-channel-priority -c conda-forge -c anaconda cookiecutter nodejs jupyter-packaging git
conda activate jupyterlab-ext
pip install jupyterlab --pre

Install extension in development mode

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
# Change directory to the renku-jupyterlab-ts directory
# Install package in development mode
pip install -e .
# Link your development version of the extension with JupyterLab
jupyter labextension develop . --overwrite
# Rebuild extension Typescript source after making changes
jlpm run build

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.

# Watch the source directory in one terminal, automatically rebuilding when needed
jlpm run watch
# Run JupyterLab in another terminal
jupyter lab

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 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:

jupyter lab build --minimize=False

Building

To build the extension for deployment as a python package, first make sure jupyter_packaging is installed. If not, install it with

pip install jupyter_packaging

Then you can create a wheel package with

python setup.py bdist_wheel

You will find the package in the dist/ directory.

Refer to the JupyterLab documentation for more detailed instructions.

Uninstall

pip uninstall jl_renku
jupyter labextension uninstall jl-renku
