node-red-contrib-loop-processing
Node-RED nodes to help a flow looping.
Description
This module has 3 nodes.
counter-loop
Using a counter variable, a flow loops like a for-loop.
Set the following inputs:
- property using as the counter variable
- initial value
- terminal value (and operator)
- increment value
If the conditions is true, a flow is sent to the lower output port ('true' outputLabel).
If false, the flow is sent to the upper output port ('false' outputLabel).
When the flow exits the loop, the counter variable can reset by setting to null, undefined or empty string. This is useful for creating a multi-loop.
array-loop
Until the end of an array, a flow loops. This node is similar to forEach or for-of,
but this node cannot handle an associated array.
Set the following inputs:
- property using as the key variable
- array
If the conditions is true, a flow is sent to the lower output port.
If false, the flow is sent to the upper output port ('end loop' outputLabel).
When the flow exits the loop, the key variable can reset by setting to null, undefined or empty string. This is useful for creating a multi-loop.
while-loop
since 0.2.0
Using a condition expression, a flow loops like a while loop.
If the expression is true, a flow is sent to the lower output port ('true' outputLabel).
If false, the flow is sent to the upper output port ('false' outputLabel).
Usage
Example flow is in examples/example.json.
Drag & drop in your Node-RED editor.
