PhantomJS script for importing collection dumps to Parse.com
/**
* PhantomJS script for importing collection dumps to Parse.com.
*
* Usage: phantomjs --ssl-protocol any import-parse-class.js <configFile> <dumpFile> <collectionName>
*
* Parameters:
* - configFile: path of a JSON file with contents:
* {
* "email": <Parse user email>,
* "password": <Parse user password>,
* "app": <Parse app name (the URL "https://parse.com/apps/<app>" must be valid)
* }
* - dumpFile: collection dump path (see https://parse.com/docs/data#data-import)
* - collectionName: name of the collection to be created (cannot be an existing collection)
*
* Notes:
* - The "--ssl-protocol any" flag is required for PhantomJS to connect to Parse
* - This script was tested on Ubuntu 14.04 with PhantomJS 1.9
* - More details about why this script is needed are here:
* http://yanirseroussi.com/2015/01/15/automating-parse-com-bulk-data-imports/
