node-red-contrib-viseo-random 0.2.0

Random call between outputs

npm install node-red-contrib-viseo-random

A Node-RED node to perform random calls according to outputs.

This node is part of project node-red-contrib-viseo powered by VISEO Technologies.

Quick Start

npm install node-red-contrib-viseo-random

Build the Node-RED Flow

The random node

  • First call: creates an array containing all the possible output values in a field according to the chosen scope.
  • Randomly shuffles the array.
  • All calls: retrieve the array,
  • Gets the value of the last element of the array,
  • Deletes this element from the array,
  • Sends the message to the output corresponding to the value.

When all the outputs were used, the array is reset and shuffled.

The scope can be set to:

  • msg - The current message in the flow ;
  • user - The msg.user field in the flow (can be stored in a database) ;
  • global - The node context (could be not working on multi-server networks) ;
