screencast

This extension was originally developed as part of the jupyterlab-topbar project, extracted into its own repository later on and brought back into jupyterlab-topbar project.

Prerequisites

  • JupyterLab 1.0+

Installation

JupyterLab 4.x

Starting from JupyterLab 4.0, extension can be distributed as a Python package. Use version 1.0.0 as other versions are incompatible with JupyterLab 4

pip install jupyterlab-theme-toggle==1.0.0

JupyterLab 2.x and 3.x

This extension requires the jupyterlab-topbar-extension extension for JupyterLab to display the visual switch:

jupyter labextension install jupyterlab-topbar-extension jupyterlab-theme-toggle

To only install the keyboard shortcut (Cmd/Ctrl+y by default):

jupyter labextension install jupyterlab-theme-toggle

Development

JupyterLab 4.x

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 jupyterlab-logout 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

JupyterLab 3.x

# create a new conda environment
conda create -n jupyterlab-theme-toggle jupyterlab nodejs
conda activate jupyterlab-theme-toggle

# required to place indicators in the top area
jupyter labextension install jupyterlab-topbar-extension

# install dependencies
jlpm

# local install of the extension
jupyter labextension install .

To rebuild the package and the JupyterLab app:

jlpm run build
jupyter lab build
