json-around

Put a JSON string around an object stream.

Example

Given this code

var through = require('through2');
var jsonAround = require('json-around');

var source = through.obj();

source
  .pipe(jsonAround('animals', {
    location: 'farm'
  }))
  .pipe(process.stdout);

source.write({name: 'horse'});
source.write({name: 'dog'});
source.write({name: 'cow'});
source.end();

stdout will (roughly) get

{
  "location": "farm",
  "animals": [
    {"name":"horse"},
    {"name":"dog"},
    {"name":"cow"}
  ]
}

and it would have been streamed in chunks like

{"location":"farm","animals":[

{"name":"horse"},

{"name":"dog"},

{"name":"cow"}]}

API

arrayPropertyName

String to use for the array's key in resulting JSON.

wrapperObject

Object that will be converted to JSON and have array added to it.
