Extraload is an ETL (EXtract, TRAnsform, LOAD) framework for Node.js. 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.

• 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

• 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.

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