jupyterlab-minio 1.0.2

JupyterLab extension for browsing Minio object storage

jupyterlab-minio

JupyterLab extension for browsing Minio object storage

This extension is composed of a Python package named jupyterlab-minio

Installation

Works on JupyterLab 3 only

pip install jupyterlab-minio

You may also need to run:

jupyter server extension enable jupyterlab-minio

to make sure the serverextension is enabled and then restart (stop and start) JupyterLab.

Usage

Configuration

If you have a ~/.mc/config.json file available then no futher configuration is necessary.

If you wish to configure through environment variables, you can do so using environment variables, for example:

export MINIO_ENDPOINT="https://s3.us.cloud-object-storage.appdomain.cloud"
export MINIO_ACCESS_KEY="my-access-key-id"
export MINIO_SECRET_KEY="secret"

You can also start without any configuration and fill in your endpoint/credentials though the form when prompted.

Development

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 jupyterlab-minio directory
# create and activate virualenv
virtualenv .venv
# install package manager for dev
pip install jupyter_packaging~=0.10
# Install/Reinstall the package in development mode
pip install -e .
# 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 jupyterlab-minio
# 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 --debug

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

# Server extension must be manually disabled in develop mode
jupyter server extension disable jupyterlab-minio
pip uninstall jupyterlab-minio

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 jupyterlab-minio within that folder.

Testing the extension

Server tests

This extension is using Pytest for Python code testing.

Install test dependencies (needed only once):

pip install -e ".[test]"
# Each time you install the Python package, you need to restore the front-end extension link
jupyter labextension develop . --overwrite

To execute them, run:

pytest -vv -r ap --cov jupyterlab-minio

Frontend tests

This extension is using Jest for JavaScript code testing.

To execute them, execute:

jlpm
jlpm test

Integration tests

This extension uses Playwright for the integration tests (aka user level tests). More precisely, the JupyterLab helper Galata is used to handle testing the extension in JupyterLab.

More information are provided within the ui-tests README.
