Of course that was too small to be true :-D -rw-r--r-- 1 hjs staff 609K 9 Jul 17:38 akka-urijs-test-opt.js That is what is left after compressing the code that is built on a parser called parboiled, a powerful library called shapeless, and the scala libraries used by the akka code. So any code that one writes will probably never be much bigger than that. Note also that this is uncompressed. It compresses down to -rw-r--r-- 1 hjs staff 128440 9 Jul 17:38 akka-urijs-test-opt.js.gz > > The scalajs team have been optimising bytecode size until now and will be starting to optimise speed next. :-) > > Henry > > Social Web Architect > http://bblfish.net/ > Social Web Architect http://bblfish.net/
