Keyboard Controls

Key Combination	Function
Right/Up Arrow or D/W key	Next slide
Left/Down Arrow or A/S key	Previous slide
Q key	First slide
E key	Last slide
SpaceBar	When autoplay={true} pauses and unpauses carousel

• Keyboard shortcuts are disabled as a default. To enable them set enableKeyboardControls prop to true.

Props

Name	PropType	Description	Default
afterSlide	React.PropTypes.func	Hook to be called after a slide is changed.
animation	React.PropTypes.oneOf(['zoom'])	Adds a zoom effect on the currently visible slide. A transform: scale(0.85) is set as default, however, the scale can be customized using zoomScale prop. Property is applied on all slides except the current 1. Use cellAlign to align the slide with zoom effect where you'd like.
autoGenerateStyleTag	React.PropTypes.bool	When set to true, it will generate a style tag to help ensure images are displayed properly. Set to false if you don't want or need the style tag generated.	true
autoplay	React.PropTypes.bool	Autoplay mode active.	false
autoplayInterval	React.PropTypes.number	Interval for autoplay iteration.	3000 milliseconds
autoplayReverse	React.PropTypes.bool	Only meaningful when autoplay is already true. When autoplayReverse is also true, autorotation cycles through slides indexes from high to low.	false
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. When cellAlign='center' or cellAlign='right', keep slidesToScroll prop set to default.Is overridden to left when transitionMode="fade"
cellSpacing	React.PropTypes.number	Space between slides, as an integer, but reflected as px
enableKeyboardControls	React.PropTypes.bool	When set to true will enable keyboard controls.
disableAnimation	React.PropTypes.bool	When set to true, will disable animation.	false
dragging	React.PropTypes.bool	Enable mouse swipe/dragging.	true
easing	React.PropTypes.string	Animation easing function. See valid easings here: D3 Easing Functions
edgeEasing	React.PropTypes.string	Animation easing function when swipe exceeds edge. See valid easings here: D3 Easing Functions
frameOverflow	React.PropTypes.string	Used to set overflow style property on slider frame.	hidden
framePadding	React.PropTypes.string	Used to set the margin of the slider frame. Accepts any string dimension value such as "0px 20px" or "500px"
heightMode	React.PropTypes.oneOf(['first', 'current', 'max'])	Change the height of the slides based either on the first slide, the current slide, or the maximum height of all slides. Overrides height set by initialSlideHeight
initialSlideHeight	React.PropTypes.number	Initial height of the slides in pixels.	100
initialSlideWidth	React.PropTypes.number	Initial width of the slides in pixels
pauseOnHover	React.PropTypes.bool	Pause autoPlay when mouse is over carousel.	true
renderAnnounceSlideMessage	React.PropTypes.func	Renders message in the ARIA live region that is announcing the current slide on slide change	Render function that returns "Slide {currentSlide + 1} of {slideCount}"
slideIndex	React.PropTypes.number	Manually set the index of the slide to be shown
slideOffset	React.PropTypes.number	While using prop animation = "zoom", you can configure space around current slide with slideOffset.	25
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. Is overridden to slidesToShow when transitionMode="fade"
slidesToShow	React.PropTypes.number	Number of slides to show at once. Will be cast to an integer when transitionMode="fade"
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	React.PropTypes.number	Animation duration/Transition speed in milliseconds
swiping	React.PropTypes.bool	Enable touch swipe/dragging	true
transitionMode	React.PropTypes.oneOf(['scroll', 'fade', 'scroll3d'])	Set the way slides transition from one to the next.	scroll
vertical	React.PropTypes.bool	Enable the slides to transition vertically
width	React.PropTypes.string	Used to hardcode the slider width. Accepts any string dimension value such as "80%" or "500px"
withoutControls	React.PropTypes.bool	Used to remove all controls at once. Overwrites the render[Top, Right, Bottom, Left]CenterControls().	false
wrapAround	React.PropTypes.bool	Sets infinite wrapAround mode.	false
zoomScale	React.PropTypes.number	Adds a number value to set the scale of zoom when animation === "zoom". The number value should be set in a range of (0,1). The default value is set to zoomScale: 0.85
opacityScale	React.PropTypes.number	Adds a number value to set the scale of the opacity for the 'scroll3d' transition mode. The number value should be set in a range of (0,1). The default value is set to opacityScale: 0.65

render*Controls

React.PropTypes.func

A set of eight render props for rendering controls in different positions around the carousel.

• Valid render props for the eight positions are renderTopLeftControls, renderTopCenterControls, renderTopRightControls, renderCenterLeftControls, renderCenterCenterControls, renderCenterRightControls, renderBottomLeftControls, renderBottomCenterControls, and renderBottomRightControls.

• The default props are set as renderCenterLeftControls for Previous button, renderCenterRightControls for the Next button and renderBottomCenterControls for the "Paging dots". To change the position or remove "Paging dots", the default positions need to be disabled by setting them to null.

<Carousel
  renderTopCenterControls={({ currentSlide }) => (
    <div>Slide: {currentSlide}</div>
  )}
  renderCenterLeftControls={({ previousSlide }) => (
    <button onClick={previousSlide}>Previous</button>
  )}
  renderCenterRightControls={({ nextSlide }) => (
    <button onClick={nextSlide}>Next</button>
  )}
>
  {/* Carousel Content */}
</Carousel>

• The function returns the props for goToSlide, nextSlide and previousSlide functions in addition to slideCount and currentSlide values. Can also remove all render controls using withoutControls.

• NOTE: The className slide-visible is added to the currently visible slide.

renderAnnounceSlideMessage

React.PropTypes.func

renderAnnounceSlideMessage render prop is a special case of the render*Controls props. It's responsibility is to render ARIA live announcement message to improve accessibility. The prop will announce the message you pass in every time the slide changes with VoiceOver enabled on your machine. The function returns only slideCount and currentSlide values.

<Carousel
  renderAnnounceSlideMessage={({ currentSlide, slideCount }) =>
    `Slide ${currentSlide + 1} of ${slideCount}`
  }
>
  {/* Carousel Content */}
</Carousel>

External Control of Carousel State

You can control the state of the carousel from your parent component as shown below:

import React from 'react';
import Carousel from 'nuka-carousel';

export default class extends React.Component {
  state = {
    slideIndex: 0
  };

  render() {
    return (
      <Carousel
        slideIndex={this.state.slideIndex}
        afterSlide={slideIndex => this.setState({ slideIndex })}
      >
        <img src="http://placehold.it/1000x400/ffffff/c0392b/&text=slide1" />
        <img src="http://placehold.it/1000x400/ffffff/c0392b/&text=slide2" />
        <img src="http://placehold.it/1000x400/ffffff/c0392b/&text=slide3" />
        <img src="http://placehold.it/1000x400/ffffff/c0392b/&text=slide4" />
        <img src="http://placehold.it/1000x400/ffffff/c0392b/&text=slide5" />
        <img src="http://placehold.it/1000x400/ffffff/c0392b/&text=slide6" />
      </Carousel>
    );
  }
}
