This topic walks through how to add a script node in YiDA workflow and integration & automation flow designers, write JavaScript within it, and consume its output in downstream nodes.

​
Use Cases

During the design phase, add a script node and write JavaScript to read values from input data, process intermediate data, and inject the result through the built-in output object. This delivers scripted data processing within business flow orchestration.

​
Access the Script Node

  • Method 1: Edit the workflow form > Open the workflow design page > Select Developer node > Script node.
  • Method 2: Edit the app > Integration & automation > Select the target automation flow and open its design configuration, then add a script node.

​
Use the Script Node

1

Add a script node

2

Write the JavaScript

3

To test the code, enter test data in inputObj and click Test to view the output

​
Consume Script Data

In any node downstream of the script node, when you select a field type, the fields exposed by the preceding script node’s output appear in the list.

​
Considerations

  • The new script node replaces the previous Groovy node and appeals to a broader developer audience.
  • The script node supports ES5 syntax only; ES6 and later syntax is not supported.
  • Batch update node processing is not yet supported.
  • Do not process data in high-memory scenarios. Exceeding 10 MB (currently set to 10 MB on a tentative basis; YiDA will adjust this based on real-world conditions) triggers a memory limit error. If CPU usage exceeds 5 seconds (for example, when an infinite loop is written), the automatic protection mechanism raises an error.
  • Network requests via xhr and fetch are not supported, and top-level objects and functions such as window, console, and print are also unavailable.
  • Defining functions inside code blocks is supported.
  • Do not add return statements outside of functions.
