When creating a carousel in React.js, an easy procedure is followed. There are two popular libraries that you can choose the results from. In addition, several built-in features are also available that can help you in creating qualitative content. So, let us see how a carousel can be created in React.js.

You can use built-in features.

One of the most popular way to create a carousel in React.js for your project is by using built-in features. Many components are available in this tool that can provide the required services. The codes are as follows:

import React, { useState } from 'react';

const Carousel = () => {
  const [index, setIndex] = useState(0);
  const length = 3;
  const handlePrevious = () => {
    const newIndex = index - 1;
   setIndex(newIndex < 0 ? length - 1 : newIndex);
  };
  
  const handleNext = () => {
    const newIndex = index + 1;
    setIndex(newIndex >= length ? 0 : newIndex);
  };
  
  return (
    <div className="carousel">
      <button onClick={handlePrevious}>Previous</button>
      <button onClick={handleNext}>Next</button>
      <p>{index}</p>
    </div>
  );
};

export default Carousel;

The code above uses the useState hook to generate a state variable known as an index. It will keep track of the current position of your Carousel. The options such as handlePrevious and handleNext functions will update the index value when one clicks the Previous and Next buttons.

At last, the markup will show the index value in the paragraph tag. You can also display the images or videos of the text you want using the codes above. In addition, one can also design and style the CarouselCarousel using options like normal CSS, CSS framework or Tailwind CSS.

Another method to generate a carousel in React.js is the pure React carousel library. It is a powerful method to generate a carousel by using various components. To use a library, one should first install a command. The command is as follows:

npm install pure-react-carousel

Below an example is given on how to use a Carousel component.

import React from 'react';
import { CarouselProvider, Slider, Slide, ButtonBack, ButtonNext } from 'pure-react-carousel';
import 'pure-react-carousel/dist/react-carousel.es.css';

const Carousel = () => {
  return (
    <CarouselProvider
     naturalSlideWidth={100}
     naturalSlideHeight={120}
     totalSlides={3}
    >

    <Slider>
      <Slide index={0}>Slide 1</Slide>
      <Slide index={1}>Slide 2</Slide>
      <Slide index={2}>Slide 3</Slide>
    </Slider>

    <ButtonBack>Back</ButtonBack>
    <ButtonNext>Next</ButtonNext>
   </CarouselProvider>
  );
};
export default Carousel;

Several benefits of using the pure react carousel library are as follows:

  • It contains an easy-to-use interface
  • It is responsive
  • Can be easily customized.

The library feature provides an option to customise the CarouselCarousel as your choice. One can add features such as pagination, navigation, autoplay, etc.

The last but not least method to create a carousel in React.js is the React responsive carousel library. Through this feature, one can create a carousel using various components. To use this library, you should install the command given below first.

npm install react-responsive-carousel

import React from 'react';
import { Carousel } from 'react-responsive-carousel';
import 'react-responsive-carousel/lib/styles/carousel.min.css';

const CarouselPage = () => {
  return (
    <Carousel>
      <div>
         <img src="https://placehold.co/100x100" />
         <p className="legend">Legend 1</p>
       </div>
       <div>

This component does not require swapping list items which leads to flicker.

import { useState, useEffect } from 'react';


const Card = ({ key, text, icon, btnText, btnLink, btnIcon, headerImg, sendInteraction }) => {

const openUrl = (url, label) => {
  window.open(url, '_blank');
}

const headText = text.length > 30 ? text.substring(0, 30) + '...' : text;

let headerSection = null;
let marginClass;
if (headerImg) {
headerSection = <div style={{ backgroundImage: `url("${headerImg}")`, }} className="carousel-bg-img">
<img src={icon} height="40px" className="carousel-logo-img" />
</div>;
marginClass = '30';
} else {
headerSection = <img src={icon} height="45px" className='mt-15' />;
marginClass = '15';
}


return (
  <li className="carousel-card carousel-li" key={key}>
    {headerSection}
    <div className={"carousel-card-text mt-" + marginClass}>
      <p>{headText}</p>
    </div>
    <a className="carousel-card-outline" href='javascript:void(0)'
     onClick={() => openUrl(btnLink, btnText)}>
     {btnIcon &&
      <span><img src={btnIcon} height="12px" /> &nbsp;{btnText}</span>
      }
     {!btnIcon &&
      <span>{btnText}</span>
     }
    </a>
  </li>
 )
}


/**
* Component to render a carousel
* @param {Array} items Items to show
* @returns
*/
export function Carousel({ items, sendInteraction }) {
  let cards = items.map((t, index) =>
    <Card key={index} icon={t.icon} text={t.text}
     headerImg= {t.headerImg}
     btnText={t.btnText} btnLink={t.btnLink} btnIcon={t.btnIcon}
     sendInteraction={sendInteraction} />
);

useEffect(() => {
document.documentElement.style.setProperty('--num', items.length);
}, [items])

const [currentIndex, setCurrentIndex] = useState(0);

const handleNextClick = () => {
  setCurrentIndex((currentIndex + 1) % items.length);
};

const handlePrevClick = () => {
  setCurrentIndex((currentIndex - 1 + items.length) % items.length);
};

const carouselStyle = {
  transform: `translateX(-${currentIndex * 20}%)`,
};

return (
