Package Exports

mongodb-extended-json
mongodb-extended-json/lib/types

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (mongodb-extended-json) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

mongodb-extended-json

MongoDB Extended JSON.

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 }

Streams

var request = require('request');
var url = 'https://cdn.rawgit.com/imlucas/mongodb-extended-json/master/test/data.json';
var EJSON = require('./');
var util = require('util');
var es = require('event-stream');

request.get(url)
  .pipe(EJSON.createParseStream('*'))
  .pipe(es.through(function(doc){
    this.emit('data',
      util.format('_id `%s` has timestamp %s\n', doc._id, doc._id.getTimestamp()));
  }))
  .pipe(process.stdout);

// Prints out:
