NodeJS section

[Mycoding]

I don't know is it good idea, but still I want to offer
"to add section of nodeJS".

I did on ExtJS+NodeJS simple cross-domain chat(very simple)

Here it is
http://vreshenie.ru/work/comet/cross-domain/chat.html

I hope this good idea.

Here is nodeJS code


var http = require('http');
var url = require('url');
var sys = require('sys');

var clients = [];//{name:'root',response:response}

http.createServer(function (request, response) {
var endConnection = function(answer){
response.end(answer);
}

var parsed = url.parse(request.url,true);
var callback = parsed.query.callback;
if(!callback){
var answer = callback+"({status:'failure',text:\"Wasn't get name callback function for cross-domain.\"})";
endConnection(answer);
}
var action = parsed.query.action;

switch(action){
case 'login':
var login = parsed.query.login;
var callback = parsed.query.callback;
clients.forEach(function (v) {
if(login==v.name){
answer = callback+"({status:'failure',text:\"This name is busy. Check another one.\"})";
endConnection(answer);
}
});

clients.push({name:login,callback:callback});
//console.log(clients);

answer = callback+"({status:'success',text:'true'})";
endConnection(answer);

break;
case 'getMessage':
var login = parsed.query.login;
var callback = parsed.query.callback;
clients.forEach(function (v) {
console.log(login==v.name);
console.log(login+"=="+v.name);
if(login==v.name){
v.response=response;
v.callback=callback;
}
});
setTimeout(function(){
answer = callback+"({status:'success',reconnect:true,text:\"Hi.\"})";
endConnection(answer);
},25000);
break;
case 'sendMessage':
var msg = parsed.query.msg;
var login = parsed.query.login;
clients.forEach(function (v) {
console.log(v.callback);
console.log(v.name);
console.log(v.response);
v.response.end(v.callback+"({status:'success',login:'"+login+"',text:'"+msg+"'})");
});
endConnection(callback+"({status:'success'})");
break;
default:
var answer = callback+"({'status':'failure','text':'This action is not defined'})";
response.end(answer);
}
}).listen(8008);
