# Extraload

Extraload is an ETL (EXtract, TRAnsform, LOAD) framework for [Node.js](http://nodejs.org). In plain English, it's a tool for taking data from one or more sources, performing any needed manipulations, and storing the transformed data somewhere else.

## Common use cases

- Importing data from XML or CSV files into a database
 - Migrating data from one database to another (for example, when switching forum software)
 - Updating Solr or Lucene indexes

## Goals

- ETL scripts should be easily understood. By using pure JavaScript instead of an amalgamation of other languages with XML, understanding a script becomes much easier.
 - Scripts should be fast. They are.
 - Supporting different data sources and databases should be easy. Extraload drivers are usually thin wrappers around pre-existing Node.js modules, making it quick and easy to support something new.

## Installation

- `npm install extraload`
 - Install any dependencies needed for the drivers you're using. Find these on the reference pages below.
