Node.js Notebooks

Features

• Node.js REPL experience in Notebooks (with rich output)
• 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 @tensforflow/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

Packages such plotly, tfjs-vis & danfo.js support rich visualzation only in the browser, wowever, this extension leverages the power of Notebooks to provide the same rich visualzations when targetting 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

• Create a file with the extension *.nnb, e.g. sample.nnb
• Or use the menu item New File... to create a Node.js notebook

Examples

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

Requirements

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

Roadmap

• Interactive Window experience
• Support user input (node.js readline for basic input in scripts)
• 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
• Support for observable inspector
