node.js - clients are continously added to socket due to server assigning ip automatically -

i have problem code have 3 clients(device) connected socket server (node.js). every time clients disconnected , connected, clients array length increasingly take 50 clients or more.i tried put 'end' emitter outside in 'data' still continuously adding clients.i don't know wrong code.

i hope me on this.

var net  = require('net');  var clients = []; var server = net.createserver(function(socket){      socket.name = socket.remoteaddress;       if(!checkarray(socket.name,clients)){          clients.push(socket);     }else{          console.log("client exist");     }           socket.on('data',function(data){         var revdata = data.tostring();          // dosomething(revdata);       socket.on('end', function () {         var indexremove = clients.indexof(socket);             if (indexremove > -1) {                 clients.splice(indexremove, 1);                 console.log("clients are"+ clients.length);             }         });     });     });   function checkarray(value, array) {        return array.indexof(value) > -1;    }  server.listen(3020,'127.0.0.1', function () {     console.log("server up!"); });  

it might have bug in first call checkarray. you're mistakenly using socket.name first parameter when should using socket itself. more specifically, logic checks if client has connected, try this:

if(!checkarray(socket,clients)){      clients.push(socket); }else{      console.log("client exist"); }
