Create new json socket. Same as net.connect.

var socket = new JsonSocket(7000, '127.0.0.1');

JsonSocket(socket)

Create new json socket from existingnet.Socket

var net = require('net');
var server = net.createServer(function (con) {
    var socket = new JsonSocket(con);

connect(port, [host])

connect(path)

Same as net.Socket.connect

on(eventType, listener)

Inherited from events.EventEmitter.

Events

connect

Emitted when socket connected (only when you pass ip, port).

json

Emitted when full json received.

socket.on('json', function (json) {
    console.log(json);
}

disconnect

Emitted when disconnected.

error

Error events are treated as a special case in node. If there is no listener for it, then the default action is to print a stack trace and exit the program.
