subgenius
Named after the eponymous Slack-promoting parody religion, subgenius is the missing Polkadot.js API scripting environment that lets you have Slack while BUIDLing around Substrate.
It makes your life easier when writing scripts that interact with the polkadot-js/api
How to use
$ npm install -g subgenius
The main executable is named bob instead of subgenius, not only because it's shorter and easier to type, but also reminiscent of the King of Slack, J. R. "Bob" Dobbs and the famous Alice and Bob.
$ bob
