Jupyter Server Extension

The Jupyter server extension source files are in the jupyterlab/ subdirectory. To use this extension, you need the Jupyter notebook server version 4.2 or later.

User installation

pip install jupyterlab
jupyter serverextension enable --py jupyterlab

Start up Jupyterlab with the command:

jupyter lab

Open a browser to the notebook server's URL (e.g., http://localhost:8888).

Developer Installation

You will need npm (preferably version 5 or later). First fork the repo in the GitHub UI and then clone locally:

git clone https://github.com/<your-github-username>/jupyterlab.git
cd jupyterlab
npm install
pip install -e . # will take a long time to build everything
jupyter serverextension enable --py jupyterlab

Start up Jupyterlab with the command:

jupyter lab

Open a browser to the notebook server's URL (e.g., http://localhost:8888).

When you make a change to JupyterLab npm package source files, run:

npm run build:serverextension

to build the changes and refresh your browser to see the changes.

To have the system build after each change to the source files, run:

npm run watch:serverextension

and refresh the browser after each successful update.

NPM Package

The npm package source files are in the src/ subdirectory.

Prerequisites

• node (preferably version 5 or later)
• Jupyter notebook server version 4.2 or later (to run examples)

Publishing packages for a JupyterLab release

We publish an npm package, a pypi source package, and a pypi universal binary wheel.

npm version patch
git push origin master --tags
npm publish
python setup.py sdist upload
python setup.py bdist_wheel --universal upload

Supported Runtimes

The runtime versions which are currently known to work are listed below. Earlier versions may also work, but come with no guarantees.

• IE 11+
• Firefox 32+
• Chrome 38+

Note: "requirejs" must be included in a global context (usually as a <script> tag) for Comm targets.

Bundle for the Browser

Follow the package install instructions first.

Any bundler that understands how to require() files with .js and .css extensions can be used with this package.

Note: This npm module is fully compatible with Node/Babel/ES6/ES5. Simply omit the type declarations when using a language other than TypeScript.
