OGC Build Status:

MAAP DPS Jupyter Extension

Frontend extension that allows users to interact with the MAAP Data Processing System (DPS) by viewing and submitting jobs.

To activate the UIs, select View My Jobs or Submit Jobs from the launcher panel.

Requirements

Package	Version
JupyterLab	4.4
Node.js	24.14.0
Python	>= 3.8

These are the recommended versions. Others may be suitable, but are not actively supported.

Install

To install the extension, run:

pip install maap-dps-jupyter-extension

Uninstall

To remove the extension, run:

pip uninstall maap-dps-jupyter-extension

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 dps_jupyter_extension directory
# Install dependencies
jlpm install
# 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 maap_dps_jupyter_extension

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 dps_jupyter_extension within that folder.

Testing

Playwright is the testing framework used. When testing locally, use the following command to start the jupyter server and run the tests:

jlpm run start & jlpm run test

To test using the interactive UI, run the following instead:

jlpm run start & jlpm run test --ui
