Scripting overview

Overview

In Etlworks, you can create very complex data integration Flows without ever writing a single line of code. However, there are certain tasks which are better handled by using the built-in scripting language. Examples include looping through inbound files, calculating a field's value on the fly, and validating data. Etlworks uses JavaScript as the default scripting language, but it is also possible to use Python.

JavaScript Tutorials

Etlworks includes a JavaScript engine called Nashorn. It is an embedded scripting engine inside Java applications. There are plenty of tutorials for Nashorn, such as:

• Java 8 Nashorn Tutorial
• Oracle Nashorn: A Next-Generation JavaScript Engine for the JVM
