Random call between outputs
A Node-RED node to perform random calls according to outputs.
npm install node-red-contrib-viseo-random
Build the Node-RED Flow
- 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) ;
