react-carousel

Feature-rich, react-way carousel component that does not suck

React carousel

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

npm i @brainhubeu/react-carousel

Typescript

npm i @types/brainhubeu__react-carousel -D

Demo

You can access a clickable demo with many examples and a live code editor here.

Usage

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

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

export default class MyCarousel extends Component {
  render() {
    return (
      <Carousel>
        <img src={imageOne} />
        <img src={imageTwo} />
        <img src={imageThree} />
      </Carousel>
    );
  }
}

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 },
);

Carousel as controlled element

You can control which slides are being shown by providing Carousel with value and onChange props

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

// ...

constructor(props) {
  super(props);
  this.state = {
    value: 0,
  };
}

// we check if we got event from input (and it has target property) or just value from Carousel 
onChange = e => this.setState({ value: e.target ? e.target.value : e });
render() {
  return (
    <div>
      <input value={this.state.value} onChange={this.onChange} type="number" />
      <Carousel
        value={this.state.value}
        onChange={this.onChange}
      >
        <img src={imageOne} />
        <img src={imageTwo} />
        <img src={imageThree} />
      </Carousel>
    </div>
  );
}

Where:

value is the current slide's index (zero based, in the example above imageOne has index 0, imageTwo has index 1 and so on)
onChange handler triggered when carousel wants to change current slide (e.g. on arrow click or on swipe)

Default arrows

You can turn default arrows on with arrows prop

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

// ...

render() {
  return (
    <Carousel
      arrows
    >
      <img src={imageOne} />
      <img src={imageTwo} />
      <img src={imageThree} />
    </Carousel>
  );
}

Where:

arrows is boolean flag that determines usage of default arrows

Custom arrows

You can define custom components for arrows using arrowLeft and arrowRight props. If you don't need to change default click listeners, add addArrowClickHandler prop. Otherwise, add click event handlers to your custom components.

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

// ...

render() {
  return (
    <Carousel
      arrowLeft={<Icon className="icon-example" name="arrow-left" />}
      arrowRight={<Icon className="icon-example" name="arrow-right" />}
      addArrowClickHandler
    >
      <img src={imageOne} />
      <img src={imageTwo} />
      <img src={imageThree} />
    </Carousel>
  );
}

Where:

arrowLeft and arrowRight are React components for arrows
addArrowClickHandler is boolean flag - default click event handlers are used when it's set to true

Passing slides as a prop

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

// ...

render() {
  const slides = [
    (<img key={1} src={abstractImage} />),
    (<img key={2} src={animalsImage} />),
    (<img key={3} src={businessImage} />),
    (<img key={4} src={cityImage} />),
    (<img key={5} src={fashionImage} />),
    (<img key={6} src={foodImage} />),
    (<img key={7} src={natureImage} />),
    (<img key={8} src={nightlifeImage} />),
    (<img key={9} src={peopleImage} />),
    (<img key={10} src={sportsImage} />),
    (<img key={11} src={technicsImage} />),
    (<img key={12} src={transportImage} />),
  ];

  return (
    <Carousel slides={slides} />
  );
}

Where:

slides is an array of slides (it must be an array, if you want to use a component as an only slide you have to pass it as a child)

Additional options

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

// ...

render() {
  return (
    <Carousel
      slidesPerPage={5}
      slidesPerScroll={2}
      animationSpeed={1500}
      autoPlay={3000}
      stopAutoPlayOnHover
      offset={50}
      itemWidth={250}
      clickToChange
      centered
      rtl
    >
      <img src={imageOne} />
      <img src={imageTwo} />
      <img src={imageThree} />
    </Carousel>
  );
}

Where:

slidesPerPage is the number of slides visible at once
slidesPerScroll is the number by which value will change on autoPlay and when arrow is clicked
animationSpeed (number) transition duration in milliseconds
autoPlay (number) slide change interval in milliseconds
stopAutoPlayOnHover (boolean) determines if autoPlay should stop when mouse hover over carousel
offset (number) padding between items
itemWidth (number) determines custom width for each slide in carousel
clickToChange boolean indicating if clicking on a slide should trigger changing the current value
centered boolean indicating if the current active slide should be aligned to the center or to the left of a carousel
rtl boolean indicating if the carousel should have direction from Right to Left (make sure to pass the rtl param to the Dots component as well)

Infinite

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

// ...

render() {
  return (
    <div>
      <Carousel
        infinite
      >
        <img className="img-example" src={someImage} />
        ...
        <img className="img-example" src={anotherImage} />
      </Carousel>
    </div>
  );
}

Responsive

All props (except value, onChange, responsive, children) can be set to different values on different screen resolution

import Carousel from '@brainhubeu/react-carousel';
import Icon from 'react-fa';

// ...

render() {
  return (
    <Carousel
      slidesPerPage={5}
      slidesPerScroll={2}
      infinite
      clickToChange
      centered
      breakpoints={{
        1000: { // these props will be applied when screen width is less than 1000px
          slidesPerPage: 2,
          clickToChange: false,
          centered: false,
          arrows: true,
          infinite: false,
        },
        500: {
          slidesPerPage: 1,
          slidesPerScroll: 1,
          clickToChange: false,
          centered: false,
          arrowLeft: (<Icon className="icon-example" name="arrow-left" />),
          arrowRight: (<Icon className="icon-example" name="arrow-right" />),
          animationSpeed: 2000,
          infinite: false,
        },
      }}
    >
      <img src={imageOne} />
      <img src={imageTwo} />
      <img src={imageThree} />
    </Carousel>
  );
}

Note: In the example above you cannot leave clickToChange value out in 500 breakpoint. In that case value from 1000 breakpoint will not be applied as the options are not inherited from higher to lower resolutions, only from default to current resolution.

Showing dots or thumbnails

There is a separate Dots component that can be used to show navigation dots.

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

// ...

constructor(props) {
  super(props);
  this.state = {
    value: 0,
  };
}

onChange = value => this.setState({ value });

render() {
  return (
    <div>
      <Carousel
        value={this.state.value}
        onChange={this.onChange}
      >
        <img className="img-example" src={someImage} />
        ...
        <img className="img-example" src={anotherImage} />
      </Carousel>
      <Dots value={this.state.value} onChange={this.onChange} number={12} />
    </div>
  );
}

It can also show thumbnails instead of dots

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

// ...

constructor(props) {
  super(props);
  this.state = {
    value: 0,
  };
}

onChange = value => this.setState({ value });

render() {
  return (
    <div>
      <Carousel
        value={this.state.value}
        onChange={this.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>
  );
}

Navigation dots can also be further customized with your own styles.

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

// ...

constructor(props) {
  super(props);
  this.state = {
    value: 0,
  };
}

onChange = value => this.setState({ value });

render() {
  return (
    <div>
      <Carousel
        value={this.state.value}
        onChange={this.onChange}
      >
        <img className="img-example" src={someImage} />
        ...
        <img className="img-example" src={anotherImage} />
      </Carousel>
      <Dots value={this.state.value} onChange={this.onChange} number={12} className={yourOwnClassName} />
    </div>
  );
}

Local running

In order to run the docs/ demo locally:

cd docs-www
if you want to connect demo with the carousel source code, replace __RC_ENV__ into development in https://github.com/brainhubeu/react-carousel/blob/master/docs-www/src/globalReferences.js#L2 and remove the .babelrc file in the root directory; otherwise, it will use the carousel code installed in docs-www/node_modules
yarn develop
