Info on flags

  • The --quantity flag represents the number of codes to be generated. It must be a number between 1 and 500000
  • The --code-length flag is used to customise the discount codes according to individual use cases. (more info in Examples)
  • The --input flag specifies the path to a CSV or JSON file containing the options the discount codes should have. If this flag is omitted, discount codes without any attributes will be generated.
  • The --output flag specifies where to output/save the generated codes. Several notes on this flag:
    • The format of the generated output will depend on the format of the file specified here. It must be CSV or JSON as these are the only supported formats.
    • If the file specified already exists, it will be overwritten.
    • The default location for status report logging is the standard output.
    • If no output path is specified, the generated codes will be logged to the standard output as a result, status reports will be logged to a discountCodeGenerator.log file
  • The --delimiter flag specifies the delimiter used in the input file and/or output file if any or both are CSV. Defaults to ',' if omitted and will be ignored if neither input nor output is CSV
  • The --multiValueDelimiter flag specifies the delimiter for multiValue cells in CSV. Note that only the cartDiscounts field if present should contain multiple values. Defaults to ';' if omitted

Examples

CSV

If we want to generate 3 discount codes, each having 9 characters(code-length), 'FOO' as prefix, and having the following data stored in a CSV file:

name.en,name.de,description.en,description.de,cartDiscounts,cartPredicate,isActive,maxApplications,maxApplicationsPerCustomer
Sammy,Valerian,greatest promo,super angebot,good;better;best,value more than 20,true,10,2

and also wanting a CSV output, we would run the following command

discount-code-generator -i /path-to-code-data/input.csv -o /path-to-write-data/output.csv -q 3 -l 9 -p FOO

The following would be written to the output file:

"name.en","name.de","description.en","description.de","cartDiscounts","cartPredicate","isActive","maxApplications","maxApplicationsPerCustomer","code"
"Sammy","Valerian","greatest promo","super angebot","good;better;best","value more than 20","true","10","2","FOObcXdOd"
"Sammy","Valerian","greatest promo","super angebot","good;better;best","value more than 20","true","10","2","FOOiNfQyy"
"Sammy","Valerian","greatest promo","super angebot","good;better;best","value more than 20","true","10","2","FOONtF2XL"

JSON

If we want to generate 3 discount codes, each having 9 characters(code-length), 'FOO' as prefix, and having the following data stored in a JSON file:

{
  "name": {
   "en": "Sammy",
   "de": "Valerian"
  },
  "description": {
   "en": "greatest promo",
   "de": "super angebot"
  },
  "cartDiscounts": [
   {
    "typeId": "cart-discount",
    "id": "good"
   },
   {
    "typeId": "cart-discount",
    "id": "better"
   },
   {
    "typeId": "cart-discount",
    "id": "best"
   }
  ],
  "cartPredicate": "value more than 20",
  "isActive": "true",
  "maxApplications": "10",
  "maxApplicationsPerCustomer": "2"
}

and also wanting a JSON output, we would run the following command

discount-code-gen -i /path-to-code-data/input.json -o /path-to-write-data/output.json -q 3 -l 9 -p FOO

The following would be written to the output file:

Additional Info
  • The cartDiscounts field in the csv should contain only the cart-discount IDs
  • The JSON output option outputs an array of json objects
  • The input and output formats are interchangeable; that means JSON output can be requested with a CSV input and vice versa
  • All fields in the input are optional. However, the file must not be empty.
  • The input option can be left out completely if no code attributes are required
