Methods

EventSocket(options)

EventSocket(port, [host])

EventSocket(path)

Create new event socket. Same as net.connect.

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

EventSocket(socket)

Create new event socket from existingnet.Socket or JsonSocket

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

emit(eventType, args...)

Send event over socket.

socket.emit('message',{foo: 'bar'});

disconnect()

Destroy connection

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).

disconnect

Emitted when disconnected.

Custom

Emitted event from peer

error

Emitted when net.Socket emit 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.

see more.

newListener, removeListener

Inherited from EventEmitter.

Protocol

We send json objects over socket then write one \0. This is c/c++ friendly protocol. 😄

Json object has name and args property. name must be string and args must be array.

{"name":"message","args":[{"foo":"bar"}]}\0
