**worker.js**

``` javascript

// Some object with methods (could be a class)

var obj = {

  x: 0,

  foo: function () {

    this.x++;

  },

  bar: function (callback) {

    callback(this.x);

  },

  baz: function () {

    return this.x;

  }

};

// create the tap class

var Remote = Tap.remote();

// create a Remote instance wrapping the obj

var remote = new Remote(obj);

// events can be sent in either direction

var console = {

  log: function () {

    var msg = Array.prototype.join.call(arguments, " ");

    remote.send("console", msg);

  }

};

```

**main.js**

``` javascript 

// create the worker

var worker = new Worker("worker.js");

// create deferred function (optional)

var makeDeferred = Q.defer.bind(Q);

// create Tap class

var Local = Tap.local(worker, makeDeferred);

// create Tap instance

var local = new Local();

// register methods available on remote object

local.methods("foo", "bar", "baz");

// invoke methods

local.foo();

// callbacks are handled automagically

// Note: they only work for 1 invocation

local.bar(function (x) {

  console.log("x:", x);

});

// invcations return promises which resolve to the invoked function's return value

// this will only work if a makeDeferred function was provided to the factory

local.baz().then(function (x) {

  console.log("x:", x);

});

// receive events

local.on(

  "console",

  console.log.bind(console, "worker:")

);

```
