Duplicating app logic is not so bad if it's just a simple one off, and you know the languages well. Haxe is pretty awesome once you start working a server/client app from a single code base. You save so much mental energy not having to do context switching on a language, and you're not afraid to make drastic changes to logic or data structures because you're making both changes at the same time.
