Usage

Chrysalis is a framework designed to ease the process of data migration and manipulation. It is built off the concept of ETL (Extract, Transform, Load). In order to function, Chrysalis requires 3 modules:

• Extractor - https://github.com/APPrise-Mobile/http-extractor
• Transformer - https://github.com/APPrise-Mobile/chryformer
• Comparator - https://github.com/APPrise-Mobile/array-comparator
• Loader - https://github.com/APPrise-Mobile/rest-loader

var Chrysalis = require('chrysalis');
var HTTPExtractor = require('http-extractor');
var Chryformer = require('chryformer');
var RESTLoader = requrie('rest-loader');

var extractor = HTTPExtractor('http://somesourceurl.com');
var chryformer = Chryformer({sourceKey: 'destinationKey'});
var loader = RESTLoader('http://somedestinationurl.com');

var chrysalis = Chrysalis();
chrysalis.setExtractor(extractor);
  .setTransformer(chryformer)
  .setLoader(loader)
  .run();
