Underscore.js Utilities as NoFlo Components
Build Status Dependency Status NPM version Stories in Ready

This module contains simple proxies of Underscore.js functions.

Feel free to contribute new components and graphs! I'll try to incorporate as soon as time allows.



It works exactly like _.groupBy and accepts individual packets, which are converted into an array at an endgroup or a disconnect to be forwarded with _.groupBy applied on it.


  • IN: packets each to be grouped by a property
  • PROPERTY: the property to group the packets by


  • OUT: the grouped object


Grouping by length of strings:

'length' -> PROPERTY GroupBy(underscore/GroupBy)
'1\n2\n3' -> IN SplitA(core/SplitStr) OUT -> IN GroupBy() OUT -> IN Output(core/Output)
