JavaScript Plugin – Run Script
Summary (SEO Meta Description):
The JavaScript plugin in WeHub runs custom JavaScript code inside workflows.
Supports dynamic logic, transformations, and calculations using workflow inputs.
Overview
The JavaScript Plugin executes custom JavaScript code within workflows.
It enables flexible logic, data manipulation, and generation of new values where built-in processors are not enough.
This is useful for applying business rules, performing calculations, or creating custom transformations directly in the workflow.
⚙️ Action: Run Script
- Description: Executes a JavaScript snippet and returns computed results.
- Use Case: Perform string manipulations, numeric calculations, or generate unique identifiers dynamically.
Configuration Options:
| Field | Type | Description |
