node-red-contrib-hcl-iterate-loop 0.0.2
This Node-RED node allows you to build a loop
node-red-contrib-hcl-iterate-loop
Node-RED node to build loops and interact with others nodes in a flow.
Basically working like a for loop.
Config iterate-loop
Below are the inputs properties required to make it possible.
- Variable name, that can be associated to a context variable(
msg,flow,global). - Value to start the loop, can be a number or a variable from a context(
msg,flow,global). - Condition to finish the loop, choosing from an operator (
==,<,<=,>,>=) and a value to compare with (number,msg,flow,global). - Increment/Decrement value (
number,msg,flow,global). Note: for decrement is enough with enter negative values and for increment positive values.
The loop will continue as long as the condition it is TRUE, throwing an output to the output label continue in each iteration.
When the condition changes to FALSE the loop will terminate an the output will be send to the output label exit
Basic example
With an example can be more straightforward to understand how this node works, the flow is available in the example folder of this repo.
