====================

PhantomJS binder for two-way communication with Node.js. An IPC library in two modules, used in conjunction with [sleepyhollow-node](https://github.com/weisjohn/sleepyhollow-node), via `stdin` and `stderr`. No `socket.io` or server-page hacks required.

### usage

To receive messages from Node.js, require and invoke `sleepyhollow`. This returns an `EventEmitter` instance which allows you to implement your own message passing system.

```

// this is PhantomJS code, not Node.js code!

var sleepyhollow = require('../index.js');

var mrhyde = sleepyhollow();

mrhyde.on('render', function(url) {

    var page = require('webpage').create();

    page.open(url, function(status) {

        page.render(url.replace(/[\/:]/g, "") + ".png");

        mrhyde.emit("rendered");

        page.close();

    });

});

mrhyde.on('end', function() {

    phantom.exit();

});

```

[See the usage example for the corresponding Node.js code](https://github.com/weisjohn/sleepyhollow-node#usage).

#### emit(event, [param])

Arguments:

1. event - String: name of the event

2. param - Mixed: optional, any `JSON.stringify()`-able value is supported

Returns: null

Example:

```javascript

myhyde.emit("payload", { prop : page.size });

```

#### on(event, listener)

Arguments:

1. event - String: name of the event

2. listener - Function(Mixed): receives a optional `JSON.stringify()`-able value

Example:

```javascript

myhyde.on('render', function(obj) {

    page.render("tmp");

})

```
