sokocket io chatbox nodejs

max budget 100 euro because i give you everything ;) Rewrite chatserver and build all missing part functions. add security for xss attacks etc. you have to use [login to view URL] with [login to view URL] functions need to do everything what needs to be done. its using mongodb for now so if you rewrite this chatserver side you have to write it in mysql storage. i dont want use mongodb. i will put my older version chatserver with more functions so you can check the logic. its called: serverold with functions from old client js. NOTE: this server doesnt work with [login to view URL] cause is from another clientside you should have to hceck the functions and rewrite from zero the serverside part.
