jupyterlab-todo-list 0.3.0

A JupyterLab side panel for to-dos with checkbox import from notebooks.

jupyterlab_todo_list

Keep lightweight to-dos inside JupyterLab. This extension adds a persistent side panel that lets you add, check off, and delete tasks while working in notebooks. Items are cached locally and synced to a small REST endpoint so they follow you between sessions.

Requirements

• JupyterLab >= 4.0.0

Install

pip install jupyterlab_todo_list

The Python package is published on PyPI, and the labextension bundle is on npm as @xlt208/jupyterlab-todo-list for anyone integrating it into custom builds. A normal pip install brings in the Python backend plus the bundled frontend automatically—no extra npm step required.

Use

1. Launch JupyterLab.
2. Open the command palette or launcher and run Open To-Do List.
3. Add tasks in the left side panel. Items are saved automatically.

The panel reopens on the next Lab session and restores your last task list.

Uninstall

pip uninstall jupyterlab_todo_list

Contributing

Development install

The jlpm command is JupyterLab's pinned version of Yarn and is already bundled with Lab. NodeJS (>=18) must be available on your PATH.

git clone https://github.com/xlt208/jupyterlab-todo-list.git
cd jupyterlab_todo_list

python -m venv .venv
source .venv/bin/activate
pip install --editable ".[test]"

jlpm install
jlpm build
jupyter labextension develop . --overwrite

During development you can keep the TS build and Lab running in watch mode:

jlpm watch   # terminal 1
jupyter lab  # terminal 2

To undo the editable install run pip uninstall jupyterlab_todo_list and remove the jupyterlab-todo-list symlink reported by jupyter labextension list.

Testing the extension

jlpm test          # Jest unit tests
jlpm lint:check    # prettier + eslint + stylelint
jlpm playwright test # UI tests (see ui-tests/README.md for setup)
