Vert.x

Vert.x combines Node.js with a distributed event bus and wraps it all inside a JVM (Java Virtual Machine).

This adds a boost of performance, while allowing complex code to be executed asynchronously, the operation Node.js is best at.

Included with Vert.x is an API which exposes it to Ruby, JavaScript, CoffeeScript, Python, and Groovy developers, allowing them all to take full advantage of the JVM environment without having to deal with Java code.

Features:

• Distributed Event Bus
• Mix Java, Ruby, JavaScript and Groovy code in the same app
• Write code as a single thread
• Asynchronous programming model
• Scalable non-blocking applications
• HTTP/HTTPS servers and clients
• TCP/SSL servers and clients
• SockJS integration
• Documentation
