BeakerX: Beaker extensions for Jupyter

BeakerX is a collection of JVM kernels and interactive widgets for plotting, tables, autotranslation, and other extensions to Jupyter Notebook and Jupyter Lab version 1.2.x and 2.x.

Version 2.x of BeakerX improves on the original solution architecture by providing independent modules that end-users can install to better tune the platform.

The documentation consists of tutorial notebooks on GitHub and a cheatsheet.

BeakerX is the successor to the Beaker Notebook (source code archive). It comes from Two Sigma Open Source. Yes we are hiring.

How to use

To install BeakerX and all kernels use:

conda install -c beakerx beakerx_all

To install only part of the solution choose which kernels to install:

conda install -c beakerx beakerx_kernel_groovy
conda install -c beakerx beakerx_kernel_java
conda install -c beakerx beakerx_kernel_scala
conda install -c beakerx beakerx_kernel_sql
conda install -c beakerx beakerx_kernel_clojure
conda install -c beakerx beakerx_kernel_kotlin

And then install optional packages:

conda install -c beakerx beakerx_kernel_autotranslation
conda install -c beakerx beakerx_tabledisplay
conda install -c beakerx beakerx_widgets

To install BeakerX extensions inside Jupyter Lab 1.2 use

// ensure you have yarn, nodejs and npm installed
conda install -c conda-forge jupyterlab=1.2
conda install -c beakerx beakerx_all

To install BeakerX extensions inside Jupyter Lab 2.x use

// ensure you have yarn, nodejs and npm installed
conda install -c conda-forge jupyterlab=2
conda install -c beakerx beakerx_all


JVM kernels with Interactive Plotting:

Autotranslation from Python to JavaScript and D3

screen shot This feature requires beakerx_kernel_autotranslation package.

Interactive Tables

screen shot This feature requires beakerx_tabledisplay package.




BeakerX contains and depends on many projects including:

The kernel is originally derived from lappsgrid, but has been rewritten in Java and refactored and expanded.

The Java support uses Adrian Witas' org.abstractmeta.toolbox.
