RingoJS

Written in Java, it provides a CommonJS conformant module library and web application framework.

It adds a number of features to Rhino that make it suitable for real-world, large-scale application development.

RingoJS is mainly geared for web applications, but can be used for command line or even GUI applications as well.

Features:

• Support for CommonJS packages to install or write additional software components.
• A fast, auto-reloading, and CommonJS-compliant module loader.
• A rich set of modules covering I/O, logging, persistence, development tools and much more.
• Scalable HTTP server and client based on the Jetty project.
