This topic explains how to add and use a script node, and how downstream nodes can consume the data it outputs.

​
Use Cases

At design time, add a script node and write JavaScript to read input data, process intermediate data, and inject the results through the built-in output object. This enables scripted data processing within business flow orchestration.

​
Access the Script Node

  • Option 1: Edit a workflow form, open the workflow design page, and select Developer node > Script node.
  • Option 2: Edit an app, go to Integration & Automation, select the target automation flow, open its design configuration, and add a script node.

​
Use the Script Node

1

Add a script node

2

Write a JavaScript script

3

Test the code by entering test data in inputObj and clicking Test to view the output

​
Consume Script Data

In downstream nodes, when you select a field type, the output fields from the preceding script node are available for selection.

​
Notes

  • The new script node replaces the previous Groovy node, making scripting accessible to a broader range of developers.
  • Script nodes support ES5 syntax only. ES6 and later are not supported.
  • Batch update node handling is not yet supported.
  • Avoid data processing that requires large amounts of memory. Exceeding 10 MB (tentative; YiDA may adjust this limit) triggers a memory-overrun error. CPU usage exceeding 5 seconds (for example, from an infinite loop) triggers the automatic protection mechanism and raises an error.
  • Network requests such as XHR and fetch are not supported. Top-level objects and functions such as window, console, and print are not supported.
  • Defining functions inside the code block is supported.
  • Do not add return statements outside a function.
