React Ultimate Carousel

“The best kind of web carousel is the one you build yourself!”

Introducing React Ultimate Carousel, a utility-first carousel for React apps that prioritizes functionality over pre-packaged features.

React Ultimate Carousel empowers you to build your carousel exactly the way you envision it. Instead of overwhelming you with a multitude of features that you may not even use, this package focuses on providing the essential functionality to your own components so that you can craft anything.

While other carousel packages may be convenient for quick implementation, they often include a plethora of features that end up bloating your builds unnecessarily.

React Ultimate Carousel gives you the tools to create all the features you want and need.

Relies on CSS Scroll Snap: https://caniuse.com/css-snappoints

Installation

You can install react-ultimate-carousel using npm or yarn:

npm install react-ultimate-carousel

or

yarn add react-ultimate-carousel

Usage

To get started, first import the component and style sheet:

import ReactUltimateCarousel from "react-ultimate-carousel";
import "react-ultimate-carousel/lib/styles/carousel.min.css";

Then simply wrap your slides with the component, its important to note that each slide requires a ref to be set using the innerRef property which is automatically provided by the component.

const Slide = ({ innerRef, index, isActive }) => {
  return (
    <div ref={innerRef} className="slide">
      Slide {index + 1} {isActive ? "is active" : "is not active"}
    </div>
  );
};

const App = () => {
  const slides = new Array(10).fill(0);

  return (
    <ReactUltimateCarousel>
      {slides.map((_, index) => (
        <Slide key={`slide-${index}`} index={index} />
      ))}
    </ReactUltimateCarousel>
  );
};

export default App;

Props

ReactUltimateCarousel

Name	Value	Description
axis	'horizontal', 'vertical'	The direction of the carousel, defaults to 'horizontal'
threshold	number	The point at which the active slide changes, defaults to 0.5
isDraggable	boolean	Sets whether the carousel can be clicked and dragged with a mouse, defaults to true
onChange	function	Callback to handle when the active slide changes, provides the slide index when triggered
renderControls	function	Provides utility props to add to your own elements which can control the slider, see below for renderControls props

Render Controls

Name	Value	Description
navigateSlide	function	A function to navigate to a slide, accepts "next", "previous" or a slide index
visibleIndex	number	Declares whether the current slide is active

Slides

Each slide will receive the following props:

Name	Value	Description
key	number	Provides the current slide index
isActive	boolean	Declares whether the current slide is active
innerRef	function	The ref that needs to be assigned to your slide element
navigateSlide	function	A function to navigate to a slide, accepts "next", "previous" or a slide index

Other

Snap stop

To prevent the carousel from navigating through multiple slides when swiping (or scrolling) and instead stop on each slide, add the following css rule to your slide component, this will be the element that has the innerRef prop attached to it:

scroll-snap-stop: always;

Render controls anywhere

If renderControls isn’t for you, and by that you want to place your own controls anywhere within your app and not directly underneath the carousel, then you can with use of a useRef. Add the following changes to your project:

const carouselRef = useRef(null);

return (
  <ReactUltimateCarousel ref={carouselRef}>
    // ...your slides
  </ReactUltimateCarousel>
);

The carouselRef variable will now provide all the carousel functions including:

const {
  visibleIndex,
  navigateSlide,
} = carouselRef.current

See src/examples/keyboard-controls/index.js for similar usage
