###Running demo locally

The demo can be launched on local machine via `webpack-dev-server`. Run the following:

```javascript
// if webpack-dev-server is not installed globally
./node_modules/.bin/webpack-dev-server

Now, you can access the application on  your localhost at following url: <a href="http://localhost:8080/demo" target="_blank">Demo</a>

###Props

####afterSlide
`React.PropTypes.func`

Hook to be called after a slide is changed.

####autoplay
`React.PropTypes.bool`

Autoplay mode active. Defaults to false.

####autoplayInterval
`React.PropTypes.number`

Interval for autoplay iteration. Defaults to 3000.

####beforeSlide
`React.PropTypes.func`

Hook to be called before a slide is changed.

####cellAlign
`React.PropTypes.oneOf(['left', 'center', 'right'])`

When displaying more than one slide, sets which position to anchor the current slide to.

####cellSpacing
`React.PropTypes.number`

####data
`React.PropTypes.func`

Used with the ControllerMixin to add carousel data to parent state.

####decorators
`React.PropTypes.array`

An array of objects that supply internal carousel controls.
Decorator objects have `component`, `position` & `style` properties. `component` takes a React component, `position` takes a predefined position string and `style` takes an object of styles to be applied to the decorator. See an example below:

```javascript
var Decorators = [{
  component: React.createClass({
    render() {
      return (
        <button
          onClick={this.props.previousSlide}>
          Previous Slide
        </button>
      )
    }
  }),
  position: 'CenterLeft',
  style: {
  	padding: 20
  }
}];

// Valid position properties are TopLeft, TopCenter, TopRight
// CenterLeft, CenterCenter, CenterRight, BottomLeft, BottomCenter
// and BottomRight
```

####dragging
`React.PropTypes.bool`

Enable mouse swipe/dragging

####easing
`React.PropTypes.string`

Animation easing function. See valid easings here: [https://github.com/chenglou/tween-functions](https://github.com/chenglou/tween-functions)

####framePadding
`React.PropTypes.string`

Used to set the margin of the slider frame. Accepts any string dimension value such as `"0px 20px"` or `"500px"`.

####frameOverflow
`React.PropTypes.string`

Used to set overflow style property on slider frame. Defaults to `hidden`.

####edgeEasing
`React.PropTypes.string`

####slideIndex
`React.PropTypes.number`

Manually set the index of the slide to be shown.

####slidesToShow
`React.PropTypes.number`

Slides to show at once.

####slidesToScroll
```
slidesToScroll: React.PropTypes.oneOfType([
  React.PropTypes.number,
  React.PropTypes.oneOf(['auto'])
])
```

Slides to scroll at once. Set to `"auto"` to always scroll the current number of visible slides.

####slideWidth

`React.PropTypes.oneOfType([React.PropTypes.string, React.PropTypes.number])`

Manually set slideWidth. If you want hard pixel widths, use a string like `slideWidth="20px"`, and if you prefer a percentage of the container, use a decimal integer like `slideWidth={0.8}`

####speed

Animation duration.

####vertical
`React.PropTypes.bool`

###ControllerMixin

The ControllerMixin provides a way to add external controllers for a carousel. To use the controller mixin, add it to your parent component as shown below:

```javascript
const App = React.createClass({
  mixins: [Carousel.ControllerMixin],
  render() {
    return (
      <Carousel ref="carousel" data={this.setCarouselData.bind(this, 'carousel')}>
        ...
      </Carousel>
    )
  }
});
```

It is required to give your component a ref value, and to pass the setCarouselData method to the data prop with the same ref as an argument.

After setting this up, your parent component has a carousels object in it's state. You can now control your carousels from other child components:

```javascript
const App = React.createClass({
  mixins: [Carousel.ControllerMixin],
  render() {
    return (
      <Carousel ref="carousel" data={this.setCarouselData.bind(this, 'carousel')}>
        ...
      </Carousel>
      {this.state.carousels.carousel ? <button type="button" onClick={this.state.carousels.carousel.goToSlide.bind(null,4)}>
        Go to slide 5
      </button> : null}
    )
  }
});

```
