How can variables be modified during the execution process?

Questions

Does the current global variable support dynamic assignment in the process. If it doesn’t work, what modification suggestions do you have
The current modification approach is to find the location where the variables are stored, change const to let, and finally register a listener to call the API.
What are the effects of changing the structure of variables.

Hey mate, use the n8n Set node for dynamic variables

  • Use the Set node to create or update variables during the workflow.
  • These values can be referenced in other nodes using expressions like: {{$json["yourVariableName"]}}.
  • This works per item, so it’s dynamic and much safer.

or

Store temporary data in Workflow Context**

  • n8n offers a workflow object you can store data in:
    workflow.set('myVariable', value)
  • You can get the value later using:
    workflow.get('myVariable')
  • This is not truly global, but works within the same workflow run.

Heads up though changing const to let can break things. n8n wasn’t designed with persistent “global state” between nodes – so it’s better to use Set, Function, or Context.
