The need to integrate carousels into our web applications frequently arises. Carousels are UI components that display multiple items in a single space.

They’re one of the most aesthetic components on a web page but often prove difficult to create from scratch, especially in frameworks like React.

React Slick is a great library for creating carousels. It offers accessibility and responsiveness — amongst other features — to help you create performant carousels. In this article, you will learn how to create a simple carousel component with React Slick and explore some of its main features.

Prerequisites

To follow along, you should have a basic understanding of

• React
• ES6 (spread operator, optional chaining)

Setting up the project

In this tutorial, we’ll create a Carousel view that displays rooms available in a hotel.

Open up your terminal and run the following command to install React:

npx create-react-app react-carousel

Next move into the react-carousel directory:

cd react-carousel

And install the following dependencies:

npm install react-slick slick-carousel react-icons

React Slick is the main library that provides us with the carousel component. slick-carousel provides styling for this component while react-icons will be used for importing icons.

All styling for this application is located in src/index.css available in the source code. View the live project.

Creating the carousel component

From the root directory, create the path components/Carousel.js and import this component into App.js:

//App.js
import Carousel from "../components/Carousel";

export default function App() {
  return <Carousel />;
}

Usually, the content displayed in each item of a carousel is similar. Therefore, we can store this content in an array as such:

// Carousel.js
import 'slick-carousel/slick/slick.css'
import 'slick-carousel/slick/slick-theme.css'

export default function Carousel() {
  const hotelCards = [

        'Discounted Meals',
        "MacBook for work use (hotel's property)",
      ],
    },
  ]

  return (
    <div className='content'></div>
  )
}

Notice I’ve also imported two stylesheets from slick-carousel at the top of the component.

Using Slider and configuring Slider settings

With the content we need, let’s begin mapping out the structure of the Carousel component. React Slick has a Slider component responsible for displaying the carousel:

// Carousel.js
import Slider from 'react-slick'

import 'slick-carousel/slick/slick.css'
import 'slick-carousel/slick/slick-theme.css'

export default function Carousel() {

  const sliderSettings = {
    slidesToShow: 3,
    slidesToScroll: 1,
    infinite: false,
  }

  const hotelCards = [
    // ...
  ]

  return (
    <div className='content'>
      <Slider {...sliderSettings}>
        {hotelCards.map((card, index) => (
          <div key={index}>
            <h2>{card.title}</h2>
            <img alt={card.title} src={card.imageSrc} width="100" height="100" />
            <p>{card.description}</p>
            <ul>
              {card.features.map((feature, index) => (
                <li key={index}>{feature}</li>
              ))}
            </ul>
            <button className='btn'>Buy Now</button>
          </div>
        ))}
      </Slider>
    </div>
  )
}

In the code block above, we’ve created a sliderSettings variable to store the carousel settings. We then spread this object into the Slider component.

sliderSettings has three configurations so far:

• slidesToShow — number to determine the number of slides to keep in view
• slidesToScroll — number to determine the number of slides to move when navigating the carousel
• infinite — Boolean to determine if the carousel continues in a loop when the last item is reached

The end result at this point should look like this:

N.B. React Slick has more carousel configurations, which we’ll get into momentarily.

Custom Next and Previous buttons

The default control buttons given by React Slick do the work, but probably don’t pass the UI test.

So, let’s create custom buttons of our own and use React Slick’s API to make them function. We’ll start by removing the buttons:

// Carousel.js
import {useState} from 'react'
import Slider from 'react-slick'
import {FaChevronLeft, FaChevronRight} from 'react-icons'

import 'slick-carousel/slick/slick.css'
import 'slick-carousel/slick/slick-theme.css'

export default function Carousel() {
  const [sliderRef, setSliderRef] = useState(null)

  const sliderSettings = {
    // removes default buttons
    arrows: false,
    slidesToShow: 3,
    slidesToScroll: 1,
    infinite: false,
  }

  const hotelCards = [
    // ...
  ]

  return (
    <div className='content'>
      <div className='controls'>
        <button>
          <FaChevronLeft />
        </button>
        <button>
          <FaChevronRight />
        </button>
      </div>
      <Slider ref={setSliderRef} {...sliderSettings}>
        {pricingCards.map((card, index) => (
          <div key={index}>
            <h2>{card.title}</h2>
            <p>{card.description}</p>
            <ul>
              {card.features.map((feature, index) => (
                <li key={index}>{feature}</li>
              ))}
            </ul>
            <button>Buy Now</button>
          </div>
        ))}
      </Slider>
    </div>
  )
}

In order to have access to React Slick’s API, we have to store an instance of Slider in a variable (state) by linking Slider‘s ref value to the state — whose initial value is set to null. When the component then renders, we can access the API through this state.

The two functions we want to use from the API are slickPrev and slickNext, which move the carousel back and forth respectively by the number specified in slidesToScroll. Applying this on the buttons, our return function should look like this:

return (
    <div className='content'>
      <button onCLick={sliderRef?.slickPrev}>
        <FaChevronLeft />
      </button>
      <button onCLick={sliderRef?.slickNext}>
        <FaChevronRight />
      </button>
      <Slider ref={setSliderRef} {...sliderSettings}>
        {pricingCards.map((card, index) => (
          <div key={index}>
            <h2>{card.title}</h2>
            <p>{card.description}</p>
            <ul>
              {card.features.map((feature, index) => (
                <li key={index}>{feature}</li>
              ))}
            </ul>
            <button>Buy Now</button>
          </div>
        ))}
      </Slider>
    </div>
  )

Responsiveness settings

React Slick also lets us control responsiveness through the responsive property.

The responsive property is an array with two values: breakpoint and settings.

• breakpoint — number (in pixels) at which we want the subsequent settings to take effect
• settings — object containing carousel settings to apply when breakpoint is reached

Add the following configuration to sliderSettings:

const sliderSettings = {
  // ...
  responsive: [
    {
      breakpoint: 1024,
      settings: {
       slidesToShow: 2,
      }
    },
    {
      breakpoint: 600,
      settings: {
       slidesToShow: 1,
      }
     }
  ]
};

With this, it becomes easier to control the view of our carousel across multiple devices without hurting the UX.

Asides from responsiveness, React Slick also has its accessibility option set to true by default. This allows arrow keys and the gesture of dragging the mouse across the carousel to move the carousel.

Below are some other settings you can try out. View all examples on their page:

const settings = { 
    fade: true ,
    speed: 500, // ms
    autoplay: false,
    initialSlide: 2,
    lazyLoad: true,
    autoplaySpeed: 3000,
}

Conclusion

React Slick is a library filled with good options that can fit into your web projects easily. With 800k+ downloads on npm, React Slick might really be the last React carousel you’ll ever need.
