For Developers

$3

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.

``bash


Clone the repo to your local environment

Install package in development mode

pip install -e ".[test]"

Link your development version of the extension with JupyterLab

jupyter labextension develop . --overwrite

Server extension must be manually installed in develop mode

jupyter server extension enable vp4jl

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.

`bash


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:

`bash
jupyter lab build --minimize=False
`

$3

`bash


Server extension must be manually disabled in develop mode


jupyter server extension disable vp4jl
pip uninstall vp4jl
`

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 vp4jl within that folder.

See RELEASE

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

`bash
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:

`bash
jupyter labextension list
``
