mongodb-extended-json

MongoDB Extended JSON parse and stringify that is friendly with bson and is actually compliant with the kernel.

Example

var EJSON = require('mongodb-extended-json');
var BSON = require('bson');

var doc = {
  _id: BSON.ObjectID(),
  last_seen_at: new Date(),
  display_name: undefined
};

console.log('Doc', doc);
// > Doc { _id: 53c2ab5e4291b17b666d742a, last_seen_at: Sun Jul 13 2014 11:53:02 GMT-0400 (EDT), display_name: undefined }

console.log('JSON', JSON.stringify(doc));
// > JSON {"_id":"53c2ab5e4291b17b666d742a","last_seen_at":"2014-07-13T15:53:02.008Z"}

console.log('EJSON', EJSON.stringify(doc));
// > EJSON {"_id":{"$oid":"53c2ab5e4291b17b666d742a"},"last_seen_at":{"$date":1405266782008},"display_name":{"$undefined":true}}

// And likewise, EJSON.parse works just as you would expect.
EJSON.parse('{"_id":{"$oid":"53c2ab5e4291b17b666d742a"},"last_seen_at":{"$date":1405266782008},"display_name":{"$undefined":true}}');
// { _id: 53c2ab5e4291b17b666d742a,
//   last_seen_at: Sun Jul 13 2014 11:53:02 GMT-0400 (EDT),
//  display_name: undefined }
