getWorkflowStaticData(type)

This gives access to the static workflow data.

You can save data directly in the workflow. This data should be small.

As an example: you can save a timestamp of the last item processed from an RSS feed or database. It will always return an object. Properties can then read, delete or set on that object. When the workflow execution succeeds, n8n checks automatically if the data has changed and saves it, if necessary.

There are two types of static data, global and node. Global static data is the same in the whole workflow. Every node in the workflow can access it. The node static data is unique to the node. Only the node that set it can retrieve it again.

Example with global data:

// Get the global workflow static data
const workflowStaticData = $getWorkflowStaticData('global');

// Access its data
const lastExecution = workflowStaticData.lastExecution;

// Update its data
workflowStaticData.lastExecution = new Date().getTime();

// Delete data
delete workflowStaticData.lastExecution;

Example with node data:

// Get the static data of the node
const nodeStaticData = $getWorkflowStaticData('node');

// Access its data
const lastExecution = nodeStaticData.lastExecution;

// Update its data
nodeStaticData.lastExecution = new Date().getTime();

// Delete data
delete nodeStaticData.lastExecution;
