Node.js Notebooks

Features

  • Enhanced REPL experience for Node.js in Notebooks (with top level awaits)
  • Run & debug JavaScript, TypeScript code in node.js
  • Built in support for typescript (ships with TypeScript & ts-node).
  • Built in support for plotly (plotly.js is shipped with the extension)
  • Rich (inline visualizations) using @tensorflow/tfjs-vis & Tensorboards
  • Excellent support for danfo.js (rich HTML output and plots)
  • Excellent support for arquero (rich HTML output)
  • Run shell scripts within the notebook cell.
  • Quickly prototype and view HTML/JavaScript/CSS output
  • Support for user input using readline

Packages such plotly, tfjs-vis & danfo.js support rich visualization only in the browser,
however, this extension leverages the power of Notebooks to provide the same rich visualizations when targeting node.js.

Use the command Open a sample node.js notebook to open a sample notebook to get started with plotly.js, danfo.js, tensorflow.js, etc.

Getting started

  • For a REPL experience use the command Open Node.js REPL
    • Consider installing the Jupyter extension for an enhance user interface (toolbars).
  • For a notebook experience, create a file with the extension *.nnb, e.g. sample.nnb
    • Or use the menu item New File... to create a Node.js notebook

Repl
Demo

Examples

  • Use the command Open a sample node.js notebook to open a sample notebook.
  • Use the command Welcome: Open Walkthrough... to checkout the samples.

Requirements

  • node.js>=12
  • node.js needs to be in the current path

Roadmap

  • Open a plain js/ts file as a notebook & vice versa.
  • Better renderers for tabular data (arquero, danfo.js, etc)
  • Vega plots without having to install vega
  • Custom node arguments

β€œSimplicity, patience, compassion.
These three are your greatest treasures.
Simple in actions and thoughts, you return to the source of being.
Patient with both friends and enemies,
you accord with the way things are.
Compassionate toward yourself,
you reconcile all beings in the world.”
