  }
});

options

general

  • masterCsv: Which CSV will be used for master set of ids.
  • requireMatchingId: If true, will not attempt to build objects where ID is not represented in all CSVs

csvFiles

  • csvFile: The alias used to reference CSV in other parts of configuration. Example above is masterCsv and slaveCsv.
    • name: The filename which can be used to read the file.
    • id: The ID that will associate the CSV row with other CSVs in this set.

objects

  • objectName: The resulting name of the object in the root of returned object, examples above are recurring and paymentToken.
    • objectProperty: The name of a property associated with the object, examples above are recurring.firstName, recurring.lastName.
      • alias: Which CSV is associated with this property.
      • name: The column in the CSV associated with this property.
      • default: If not found or empty, the default value to use instead.
      • rules: Validation rules to run against property value.
        • lib: Which library to use for validation, see validation section below.
        • def: The function name which will be invoked on the lib.
        • args: Any args in addition to the already passed property value.

validation

Currently supported libraries:

If failures occur, the details will be appended to the object root under:

object.failures

Failures do not result in objects being removed from list, it is up to the caller to decide what to do if validation failures are present.
