PurpleJS – A JavaScript application framework running on the JVM

I did a presentation on using Nashorn (and jjs) about a year ago at SacJUG (our local Java user group). It's pretty interesting the level at which you can intermix Java and Javascript in Nashorn.

I tinkered with the idea of using a library called Spark on Netty to make web services in JS, but this library (and others mentioned here) actually did the job :-)

I also did a lightning talk demo on Nashorn vs Node performance a few months ago (local JS user group).

For the little string mashing benchmark I put together (originally to compare sequential / fork / thread performance in various languages), Nashorn's (Java 8) JIT eventually catches up and passes Node. Alas, it's one of those "O(n) for large n" problems where n has to be around a million before this happens.

... And Perl still mops the floor up with all of them. (Perl is good at string handling, even if not so much at many other things)

I actually used Spark via the "Nasven" wrapper for maven to create the simple thumbnail server I wrote about on my post (it's at the end of a lot of boring text): https://github.com/smcl/thumbooo
