parse-mongodb-export's Introduction

Node.js - parse-mongodb-export

Parse JSON file migration tool for Mongolab.

Why?

Native Parse.com JSON file export is incompatible with Mongolab import. This utility can help refactor the Parse JSON format to a format which is compatible with Mongolab JSON schemes to help preserve objectId and date formats.

Converts Parse JSON from this:

{ "results": [
	{
        "automaticUser": true,
        "avatar_url": "",
        "createdAt": "2014-01-13T12:11:47.185Z",
        "didBuyCredits": false,
        "isActive": true,
        "objectId": "08Ve1yyCrp",
        "tokens": 2,
        "updatedAt": "2014-01-13T14:52:14.141Z",
        "username": "ChunkyGoat3803"
    },
    ...

To this JSON format which is compatible with Mongolab JSON import:

[
  {
        "automaticUser": true,
        "avatar_url": "",
        "created_at": {
          "$date" : "2014-01-13T12:11:47.185Z"
          },
        "didBuyCredits": false,
        "isActive": true,
        "_id": "08Ve1yyCrp",
        "tokens": 2,
        "updated_at": {
          "$date": "2014-01-13T14:52:14.141Z"
          },
        "username": "ChunkyGoat3803"
    },
    ...
    ]
