#### Detect if the network is up (do we have connectivity?)

![internet!](https://raw.githubusercontent.com/feross/connectivity/master/img.jpg)

The module answers the most important question: is the cat-picture delivery system working?

### usage

```js

var connectivity = require('connectivity')

connectivity(function (online) {

  if (online) {

    console.log('connected to the internet!')

  } else {

    console.error('sorry, not connected!')

  }

})

```

Also works in the browser with [browserify](http://browserify.org/)!
