A JavaScript kernel for JupyterLite
Project description
jupyterlite-javascript-kernel
A JavaScript kernel for JupyterLite.
Requirements
- JupyterLite >=0.3.0
This kernel was originally maintained as part of the main JupyterLite repository, and was moved to its own repository for the JupyterLite 0.3.0 release.
Install
To install the extension, execute:
pip install jupyterlite-javascript-kernel
Uninstall
To remove the extension, execute:
pip uninstall jupyterlite-javascript-kernel
Contributing
Development install
Note: You will need NodeJS to build the extension package.
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 jupyterlite-javascript-kernel 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 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 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 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
Development uninstall
pip uninstall jupyterlite-javascript-kernel
In development mode, you will also need to remove the symlink created by jupyter labextension develop
command. To find its location, you can run jupyter labextension list to figure out where the labextensions
folder is located. Then you can remove the symlink named @jupyterlite/javascript-kernel within that folder.
