Parse and stringify JSON data using promise to gracefully handle success and failures if the data is invalid. See the examples below for usage instructions. This module use bluebird for Promise/A+ support.

Usage Instructions

Parsing JSON data

var json = require('json-promise');
var str = [
    '{"menu":{"id":"file","value":"File","popup":' 
    ,'{"menuitem":[{"value":"New","onclick":"CreateNewDoc()"},' 
    ,'{"value":"Open","onclick":"OpenDoc()"},{"value":"Close",' 
    ,'"onclick":"CloseDoc()"}]}}}'
].join('');

json.parse(str)
    .then(function onParse(obj) {
        // do something with the data object
    })
    .catch(function onParseError(e) {
        // the data is corrupted!
    });

Stringify JSON data

var json = require('json-promise');
var obj = {
  "menu": {
    "id": "file",
    "value": "File",
    "popup": {
      "menuitem": [
        {
          "value": "New",
          "onclick": "CreateNewDoc()"
        },
        {
          "value": "Open",
          "onclick": "OpenDoc()"
        },
        {
          "value": "Close",
          "onclick": "CloseDoc()"
        }
      ]
    }
  }
};

json.stringify(obj)
    .then(function onStringify(obj) {
        // do something with the string
    })
    .catch(function onStringifyError(e) {
        // the data is corrupted!
    });
