Custom implementation of JQ variables

automation SAP November 2022
JQ Variables

Overview

Implemented custom JQ variable support, enabling users to define and reuse variables in JQ expressions for cleaner, more maintainable data transformations.

Key Features

  • Variable Declaration: Define named variables for reuse
  • Improved Readability: Break complex expressions into manageable pieces
  • Reduced Duplication: Reference variables multiple times
  • Easier Debugging: Inspect intermediate results
  • Better Maintainability: Update logic in one place

Example

{
  "variables": {
    "userId": ".user.id",
    "userName": ".user.name"
  },
  "expression": "{id: $userId, name: $userName}"
}

Technical Approach

  • Custom JQ expression parser
  • Variable scope management
  • Integration with existing JQ executor
  • Validation and error handling
