Simple application made in nodejs for mass generation of data.

His intention is to facilitate when creating a large batch of random data following a defined model, ensuring that each of the results is different from the others.

The CLI environment needs a JSON input to be used as model to the generated dataset. This input can be done both via file or stdin. The entity of the items must follow the key pattern and parameters.

Supported Data Types:

E.g.

{
  "active": {
    "type": "bool",
    "probability": 70
  },
  "wallet": {
    "type": "currency",
    "prefix": "$",
    "min": 7500,
    "max": 15000
  },
  "createdAt": {
    "type": "date",
    "min": "2000-01-01T00:00:00.000Z",
    "max": "2019-12-31T23:59:59.000Z",
    "format": "dd/MM/yyyy HH:mm"
  },
  "status": {
    "type": "enum",
    "count": 1,
    "items": ["online", "offline"]
  },
  "id": {
    "type": "GUID"
  },
  "bio": {
    "type": "longtext",
    "count": 5
  },
  "mail": {
    "type": "mail",
    "count": 2,
    "separator": ["_", ".", ""],
    "sulfix": ".org.com"
  },
  "name": {
    "type": "name",
    "count": 2
  },
  "phone": {
    "type": "phone",
    "pattern": "+99 (99) 9 9999-9999"
  }
}

The input file is specified via -m parameter. E.g. npx genmock -m model.json. If no file is specified, then GenMock will expect the file contents to be inputted via stdin.

The output data will be written into stdout if no file is specified. To specify a file its used the -o param. E.g. npx genmock -o output.json.

-n, -number: Specify the amount of data to be generated. E.g.: npx genmock -n 10

If you have any cool ideas for the project, I did not fail to open an issue to discuss.
