Interactive NodeJS Notebook cli-tool

V800 team e63e30c5fe45b349b3b83e4c332ee23f 1540840864



Notes help us think, document, experiment and play with ideas. That's the main reason for creating this project. I'm a big fan of jupyter notebooks, gists, pastebins and cloud documents but I'm still searching for something better to comunicate, express myself and save my JS notes.


Install the command line cli-tool to have a better experience:

$ npm i -g jsnotebook2
$ jsnotebook2


  • Insert math formulas, like the following: \sum i = 1 + 2 + 3 + ... + n
  • Execute javascript code rows by pressing shift+enter during edition, you can repeat this operation multiple times and receive the updatedstdout, stderr
  • To take the most out of the experience you might consider looking into markdown and mathjax language references
