vert.x

What is vert.x?

The next generation polyglot asynchronous application framework. (Formerly known as node.x)

  • Runs on the JVM.
  • Embraces the good bits of event driven frameworks like node.js then adds some even juicier bits.
  • Everything is non-blocking.
  • Polyglot. vert.x will be usable from multiple languages: Ruby, Groovy, Java, JavaScript, Python, Clojure, Scala. Currently we support Java and Ruby and have partial Groovy support. Write your code in the language you choose. Leverage the power of vert.x from that language.
  • Goes with the recent developments with InvokeDynamic in Java 7 and bets on the JVM being the future premier runtime for dynamic languages.
  • Enables you to create network servers or clients incredibly easily.
  • True scalability. Unlike other well-known event-driven frameworks, you can have more than one event loop per process. No more spinning up 32 instances just to utilise the cores on your server.
  • Incredibly simple concurrency model. Write your code as single threaded but watch it scale across multiple cores. No need to worry about race conditions or locks.
  • Understands multiple network protocols out of the box including: TCP, SSL, HTTP, HTTPS, Websockets.
  • Efficiently serve static files from the filesystem bypassing user-space altogether.
  • Simple Sinatra/Express style resource based web routing.
  • Distributed event bus. Multiple vert.x instances work together seamlessly to provide a distributed event bus
  • SockJS support

What is the status of vert.x?

The second binary release, vert.x 0.2, has been released.

You can find the Road-map here

What is the architecture?

vert.x core is currently written in Java. We then provide a thin layer in each of the JVM languages we support which allows the API to be used in each of the supported languages.

We do not expose the Java API directly in the other languages since we wish to retain the normal coding idioms for each supported language.

We don't leak Java stuff to other languages through the API.

vert.x internally uses Netty for much of the asynchronous IO.
