Counter

Description

This module increments by 1 the value of the contador field in the flow data. If the contador field does not exist or is not a valid number, it is initialized to 0 before incrementing. It is a simple utility module that can be used as part of loops in workflows to count iterations, control retry limits, or keep a count of processed elements.

Configuration

Parameters

Parameter	Type	Required	Description
contador	string	No	Initial counter value (defined in the scheme). Default "1".

Output

{
  "nextModule": "siguiente_modulo",
  "data": {
    "contador": 2,
    "otros_campos": "se preservan"
  }
}

Usage Example

Basic case

{
  "contador": "1"
}

With input data:

{
  "contador": 5,
  "nombre": "proceso_batch"
}

Result: { "contador": 6, "nombre": "proceso_batch" }

Notes

• The increment is always +1
• If contador is not a valid number (NaN), it is reset to 0 before incrementing
• A copy of the data object is created to avoid undesired mutations
• All other fields of the input object are preserved in the output
