Add JavaScript support for Spring dynamic languages [SPR-7592]

[spring-projects-issues]

Tomasz Nurkiewicz opened SPR-7592 and commented

Spring currently supports Groovy, JRuby and BeanShell dynamic languages. I would like to suggest adding support for JavaScript. Because Rhino engine is embedded in Java 6 JRE, no additional libraries are needed since that version.

I have already implemented (GitHub) rough version of this feature (including several unit tests) and explained it here.

I think this is a great idea - Server Side Javascript has been getting a lot of attention (e.g. V8 and node.js) and Rhino is really a mature implementation we're lucky to have it on the JVM.

In fact I was a little surprised/disappointed Groovy's Dynamic Language Support didn't already support Javascript - after all if you define "popularity" in terms of numbers of developers who know it, Javascript is in fact more popular than the other dynamic languages already supported.

I did download Tomasz rough version, and it appears that he's made his changes right within/alongside the current spring code base, I assume to make incorporation in the official Spring code base as easy as possible.

So I vote for this and I hope others do as well!! :)

Any updates on this issue? Few people contacted me and asked about this feature.

With the enormous number of REST services spitting out JSON these days and JavaScript built right into the JVM, it seems silly to constantly be marshaling JSON back and forth through Java objects. RingoJS is awesome in that it lets me work with JSON as God intended while running on the JVM thus giving me access to Spring abstractions, but I would like more seamless integration with Spring. How about adding Rhino and Nashorn support to Spring's list of dynamic languages. Better yet, make a huge splash and support CommonJS package loading and NPM libraries in the same runtime.

Since Nashorn Javascript engine use JSR-233 ScriptEngine, Invocable and Compilable types, maybe this issue should be closed in favor of #9888.

Superseded by #9888.
