You could, and that might get you the performance you need, but if not I would likely use https://github.com/node-ffi/node-ffi https://github.com/node-ffi/node-ffi or maybe http://www.swig.org/ http://www.swig.org/ to call out to C++ or C code. There's probably also a way to call Java, ( a quick search suggests https://github.com/joeferner/node-java https://github.com/joeferner/node-java perhaps) but I can't speak to that in particular.
