Feature Request - toJSON

[thamblin]

Would it possible to have a function added for converting an element to a JSON encoded string? The toString function when applied to objects and arrays doesn't produce a true JSON string.

This is useful when the JSON you're processing is variable or the schema is not concrete and you want to create processes that will handle the input regardless of how the data changes

Example:

input

{
  "x": [ 3, 2, 1, "go"  ],
  "small": "small",
  "BIG": "BIG",
  "people": [
    {
      "firstName": "Bob",
      "lastName": "Smith",
      "address": {
        "state": null
      }
    },
    {
      "firstName": "Sterling",
      "lastName": "Archer"
    }
  ],
  "null_value": null,
  "boolean_value": false,
  "int_value":  13
}

spec

[{
  "operation": "modify-overwrite-beta",
  "spec": {
    "*": "=toJSON"
  }
}]

output

{
  "x" : "[3,2,1,\"go\"]",
  "small" : "\"small\"",
  "BIG" : "\"BIG\"",
  "people" : "[{\"firstName\":\"Bob\",\"lastName\":\"Smith\",\"address\":{\"state\":null}},{\"firstName\":\"Sterling\",\"lastName\":\"Archer\"}]",
  "null_value" : "null",
  "boolean_value" : "false",
  "int_value" : "13"
}
