NodeJS chat

I need a chat written in javaScript/JQuery working with NodeJS (no Ajax/PHP). Requirements: - visitor must not be able to set username. username must be automatically set with the one from the PHP Session so your application must be able to catch it within the javascript. Only members logged in my member area must be able to post messages in the chat. (we will NOT use Memcache, php-fpm, etc for this) - the application must check that username is valid and visitor is not hacking. to do it, javascript must send username + a md5 (i will code it), then i your NodeJS app you must check that username + hash (+ salt string) are valid then allow him to post messages if "true". - chat must be "multi room". the member cannot change room and not see other rooms, room will be automatically set when he joins a specific page on my website. for example, if he opens webpage "[login to view URL]", the chat within the webpage must show the chat messsages from room name "hello1", if he goes to page "[login to view URL]", room will be automatically "blabla" and username will be $_SESSION['username'], etc - you must secure the user inputs against injections. you can do it with the node package called "ent" ( for example: [login to view URL](message) ), same with jquery ( for example: [login to view URL]('p').text(msg); ) - users must be able to put smileys simply typing codes like "[:happy]" or "[:sad]", that will be parsed and give something like "<img src="/img/[login to view URL]" />". no need for user interface for this smiley app. - users must be able to set color of nickname in chat. i will code it somehow in php, so all you have to do is javascript, like "var color = $_SESSION[usercolor];" or something. It is quite simple, so you just need to send the variable to nodejs with your javascript, you dont need to code a nickname colorpicker for your app. - code must be commented+++ and indented. - that's all and quite basic for now but i may hire you again to improve it with new features. - to start with, you can copy/paste this example ( [login to view URL] ) and customize it with the requirements, 70% of the work is already done here. - you must be very familiar with NodeJS and JQuery. - paste the code "6F3" when you bid to prove you read this. - i have the time so it should be done within 7-14 days max. - i expect you to be available in freelancer.com chat and communicative.
