flashio facilitates JSON/Object communication from Flash to node.js over a TCP socket.

The goal of this project is to create a reliable way for Flash to talk to node.js over a typical (not a websocket) TCP connection.

Server (node.js)


Install via npm npm install flashio


You can create a server via

var flashio = require('flashio);
var server = flashio.createServer(port);

You can then listen to various events via

server.on('connect', function(data) {
  console.log( + " connected");

Events are

  • .on('data', function(data)) emitted when client sends data
  • .on('close', function(data)) emitted when client disconects
  • .on('error', function(error)) emitted on error
  • .on('connect', function(data)) emitted on connect

All event callback parameters (data or error) contain a data.socket or error.socket value representing a client's socket. Each socket has a unique id property via

In order to send data to the client use

server.send(socket, { message: "Hi client" });


server.sendToId(, { message: "Hi client" });

Client (flash)


Find the flashio package in this repository under src/flash/src/flashio. Include this package in your AS3 project.


You can create a client via

var client:FlashIO = new FlashIO(host, port);

You can listen to various events via

client.addEventListener(DataEvent.DATA, function(event:DataEvent):void {

Events are

  • Event.CONNECT
  • Event.CLOSE
  • IOErrorEvent.IO_ERROR
  • SecurityErrorEvent.SECURITY_ERROR
  • flashio.DataEvent

In order to send data to the server use

client.send({ message: "Hi server" });
