Loop GroupControl FlowwidgetsCoreloopGroup· Version 1.0.0
Wrap a block of nodes and run it once for each element of an array.
Loop Group is a container. Drop the body inside it and wire the onIterate exit to the first node: each pass writes the current element to the variable named in Item Variable, runs the body, and comes back for the next element. When the array runs out, or the list is empty, the flow takes onFinished. Maximum Iterations is a runaway guard rather than a batch size: tripping it takes invalidInput, with a message naming the limit and the length of the array, so a cap set below the length of the list is reported instead of quietly dropping the rest. A Loop Break node inside the group stops early and takes break instead, leaving the remaining elements unprocessed. Use the plain Loop node when you would rather draw the body as an explicit back edge than box it on the canvas.
Fields
| Field | Type | Required | Description |
|---|---|---|---|
Arrayarray | string | Required | The list to walk. A variable holding a JSON array, or a JSONPath that resolves to one. Example: $(order.items) |
Item VariableitemVariable | string · variableName | Required | The variable name the current element is written to before each pass. Read it inside the group with the $(name) syntax. Example: item |
Maximum IterationsmaxIterations | number | Required | The most passes this loop may make. A runaway guard, not a batch size: reaching it with items still unprocessed stops the loop on the invalid input exit, naming the limit and the length of the array, rather than reporting a run that dropped most of its work as finished. Example: 100 |
Exits
System exits (auto-injected, hidden when unwired): invalidInput, fallback.
