Javascript on Vert.x with Nashorn

This module uses the Nashorn JavaScript engine to power Vert.x JavaScript verticles This language module uses the generic vert.x Javascript API in mod-lang-js. The API documentation is the same as for lang-js and lang-rhino, and can be found on the lang-js CI server.

API Documentation

This module also supports CoffeeScript.

• Important note. The Nashorn engine is an intrinsic part of the Java 8 JDK implementation. In order to use this module you will need to be running Vert.x with JDK 1.8.0 or later *

Usage

By default, vert.x runs Javascript with Rhino. Change this by creating a langs.properties file at the root of your project that looks something like this.
