Vert.x – JVM Polyglot Alternative to Node.js

So it's more like Twisted (a library) than Node (a runtime + a library).

Trying to install this on Ubuntu. Is it me or is the "binary" download link [1] not really a binary download link?

The install pre-requisites recommends that Windows users install a linux VM - but I found the beta 11 version works directly.

Impressive. It's basically a kinda-sorta-rewrite of Node.js APIs on the JVM.

Looking through the docs, the main difference I see is that this is opting for a comparatively heavy-core approach which contrasts with Node's ruthless minimalism + third-party modules.

For example:

-file system access is convoluted with HTTP handling: req.response.sendFile()

-pieces of web framework functionality by default, but no full solution (RouteMatcher)

-integrated WebSockets with a novel but unconventional accept/reject API

-heavyweight SockJS integration

It will be interesting how all of his plays out. And I'm definitely interested in hearing evidence for claims such as

> a run-time with real concurrency and unrivalled performance

which is?
