Why?

There are some great carousels (like slick) that do not have real React implementations. This library provides you with carousel that is not merely a wrapper for some jQuery solution, can be used as controlled or uncontrolled element (similar to inputs), and has tons of useful features.

Installation

Basic

npm i @brainhubeu/react-carousel

Typescript

npm i @types/brainhubeu__react-carousel -D

CDN

If you don't use any bundler like Webpack, you can add these scripts to your HTML file, body section:

<script crossorigin src="https://unpkg.com/react@16/umd/react.development.js"></script>
<script crossorigin src="https://unpkg.com/react-dom@16/umd/react-dom.development.js"></script>
<script crossorigin type="text/javascript" src="https://unpkg.com/@brainhubeu/[email protected]/lib/react-carousel.js"></script>

Make sure to use a version ending with -cdn.

Then, you can use the following global variables:

• BrainhubeuReactCarousel
• BrainhubeuReactCarouselDots
• BrainhubeuReactCarouselItem
• BrainhubeuReactCarouselWrapper

SSR

When using @brainhubeu/react-carousel with SSR (Server-side Rendering), we recommend Next.js as @brainhubeu/react-carousel currently doesn't work on the server side so it must be rendered on the client side (maybe we'll provide server-side working in the future).

import dynamic from 'next/dynamic';

const { default: Carousel, Dots } = dynamic(
 () => require('@brainhubeu/react-carousel'),
 { ssr: false },
);

Usage

By default, the component does not need anything except children to render a simple carousel. Remember that styles do not have to be imported every time you use carousel, you can do it once in an entry point of your bundle.

import React from 'react';
import Carousel from '@brainhubeu/react-carousel';
import '@brainhubeu/react-carousel/lib/style.css';

const MyCarousel = () => (
  <Carousel plugins={['arrows']}>
    <img src={imageOne} />
    <img src={imageTwo} />
    <img src={imageThree} />
  </Carousel>
);

export default MyCarousel;

Showing dots or thumbnails

There is a separate Dots component that can be used to fully control navigation dots or add thumbnails.

import Carousel, { Dots } from '@brainhubeu/react-carousel';
import '@brainhubeu/react-carousel/lib/style.css'; import { useState } from 'react';

const MyCarouselWithDots = () => {
  const [value, setValue] = useState(0);

  const onChange = value => {
  setValue(value);
  }

  return (
    <div>
      <Carousel
        value={value}
        onChange={onChange}
      >
        <img className="img-example" src={someImage} />
        ...
        <img className="img-example" src={anotherImage} />
      </Carousel>
      <Dots
        value={this.state.value}
        onChange={this.onChange}
        thumbnails={[
          (<img key={1} className="img-example-small" src={abstractImage} />),
          ...
          (<img key={12} className="img-example-small" src={transportImage} />),
        ]}
      />
    </div>
  );
};

export default MyCarouselWithDots;

Props

You can access a clickable demo with many examples and a live code editor by clicking on a Prop name.

Carousel props

| Prop | Type | Default | Description | | --- | --- | --- | --- | | value | Number | undefined | Current slide's index (zero based, depends on the elements order) | | onChange | Function | undefined | Handler triggered when current slide is about to change (e.g. on arrow click or on swipe) | | slides | Array | undefined | Alternative way to pass slides. This prop expects an array of JSX elements | | itemWidth | Number | undefined | Determines custom width for every slide in the carousel | | offset | Number | 0 | Padding between items | | animationSpeed | Number | 500 | Determines transition duration in milliseconds | | draggable | Boolean | true | Makes it possible to drag to the next slide with mouse cursor | | breakpoints | Object | undefined | All props can be set to different values on different screen resolutions |

Plugins

You can extend react-carousel default behavior by applying plugins shipped within carousel or by creating and applying your own ones

Plugins documentation

Dots props

| Prop | Type | Default | Description | | --- | --- | --- | --- | | value | Number | slide position in the slides Array | Current Carousel value | | onChange | Function | undefined | onChange callback (works the same way as onChange in Carousel component) | | number | Number | Amount of slides | Number of slides in the carousel you want to control | | thumbnails | Array of ReactElements | undefined | Array of thumbnails to show. If not provided, default dots will be shown | | rtl | Boolean | false | Indicating if the dots should have direction from Right to Left |
