Direction

Properties by default are reactive and bi-directional, meaning they are both read and write. However, indicating how the Property is used can be very useful for the user to understand the intent of the properties. The direction Property field can be used to do this.

Direction Values​

  • both: This Property can be both read (get) or written (set). For example, both context.get('value') and context.set('value', newValue) are used in the node. This is the default.
  • output: This Property is written (set) by the node and not read. For example, only context.get('query') and not context.set("query", newValue) is used in the node.
  • input: This Property is only read (get) by the node. For example, only context.get('result') and not context.set('result', newValue) is used in the node.

Example​

properties.yaml
query:
  datatype: text
  direction: input
result:
  datatype: json
  direction: output
value:
  datatype: json
  direction: both
