Programmatic-style nodes only

This guidance applies to programmatic-style nodes. If you're using declarative style, Localmind Automate handles paired items for you automatically.

Use Localmind Automate's item linking to access data from items that precede the current item. Localmind Automate needs to know which input item a given output item comes from. If this information is missing, expressions in other nodes may break. As a node developer, you must ensure any items returned by your node support this.

This applies to programmatic nodes (including trigger nodes). You don't need to consider item linking when building a declarative-style node.

Start by reading Item linking concepts, which provides a conceptual overview of item linking, and details of the scenarios where Localmind Automate can handle the linking automatically.

If you need to handle item linking manually, do this by setting pairedItem on each item your node returns:

// Use the pairedItem information of the incoming item
newItem = {
	"json": { . . . },
	"pairedItem": {
		"item": item.pairedItem,
		// Optional: choose the input to use
		// Set this if your node combines multiple inputs
		"input": 0
};

// Or set the index manually
newItem = {
		"json": { . . . }
		"pairedItem": {
			"item": i,
			// Optional: choose the input to use
			// Set this if your node combines multiple inputs
			"input": 0
		},
};
