The Ultimate guide to React responsive carousel

A carousel in React is a slideshow of a series of several images. React Carousel is built with the help of CSS transitions and Javascript coding. A carousel in React can include any element like image, text, videos, markups, etc. In React, you can create a Carousel that has an interactive control like a forward and backward button and image indicators.

React supports a vast collection of highly dynamic and interactive Carousels. Also, it has several libraries from where you can build a carousel. These libraries are linked to the React app as an additional plugin, and you can start using them to make a carousel. You can create any type of image carousel with interactive controls and also without them. In React, carousels do not determine their dimensions on their own; you will need to specify them. This is because you might add custom stylizing, transitions, and text, all of these are required manual modifications. The indicators and elements are not essential to be passed explicitly while making a carousel in React; you can add them anywhere.

 

Building a React Carousel

 

1. Create a data containing object

 

Initially, you will need to make a component that can hold all the data of the Carousel. This component should be an array that you can set the slides that will change the image or text accordingly.  

 

export default [{

title: 'Turn the music up!',

description: '',

},

{

title: 'Choose your music',

description: 'The world is full of music; why should you have to listen to music someone else chose?',

},

{

title: 'Unlimited, streaming, ad-free',

description: 'No arbitrary limits. No distractions.',

},

{

title: 'Mobile enabled',

description: 'Listen to your music on the go. This streaming service is available on all mobile platforms.',

}

]; 

 

2. Components of the Carousel

Next, you will have to create components for the Carousel. Those components will contain all the interactive elements, like the indicators, buttons, next and previous buttons, etc. Let's include forward and previous buttons as arrows. For this, you should have the images for the arrows you will be using in the Carousel. Both the arrows are going to be similar; only the functions will be different. You will have to add <div> functions that will have the images you will be using for the buttons. You can also add an onclick function so that they will be executing while they are clicked.

import React, { Component } from 'react';class LeftArrow extends Component {

 render() {

   return(

     <div className='backArrow' onClick={this.props.goToPrevSlide}>

       <i className='fa fa-angle-left fa-3x' aria-hidden='true'></i>

     </div>

   )

 }

}export default LeftArrow;

 

After creating navigation buttons, you will have to create another component that will have the code for switching the slides and the navigation buttons. Here you will add an Onclick behavior to the navigation arrows. To display the slideshow in a continuous format, you will need to make a never-ending loop. For instance, you are on the last slide, and after that, you click the next button you will be shown the first slide and vice versa.

Before starting to create the components, you are supposed to build two additional states. 

These states will help to simplify the further procedure. So first create an activeIndex state. This state will display the current slide on the web page in which the output is being shown. You can put the value to an index number, and the respective slide will be displayed on the web page. Secondly, create a length state; this will provide the size of the array of the Carousel. This will help to determine from which slide you are supposed to loop the slides.

As you have created the states required of the React carousel now, you can start defining the functions. These functions will have the logic for the navigation of the slides through the arrow. You can pass the props to the arrow functions describing the control functions.

goToNextSlide() and goToPrevSlide() are the two functions that will have the logic to move forward and backward in the slideshow. They will have the logic to increment or decrement the index number of the slides.

 

goToPrevSlide() {

   let index = this.state.activeIndex;

   let length = this.state.length;if(index < 1) {

     index = length - 1;

   }

   else {

     index--;

   }this.setState({

     activeIndex: index

   });

 }goToNextSlide() {

     let index = this.state.activeIndex;

     let length = this.state.length;if(index === length - 1) {

       index = 0

     }

     else {

       index++;

     }this.setState({

       activeIndex: index

     });

 }

 

Here an if-statement is used to perform the looping. With the help of looping, you will be redirected to the first slide after moving further from the last slide. After this, you will have to determine the components that will be displayed on the screen of the user. Here you will show left and right arrows, slide indicators, also you pass the props of the functions that were created previously.

 

render() {

return (

<div className='slider'>

<div className='slider-items'>

<LeftArrow

goToPrevSlide={() => this.goToPrevSlide()}

/>

<div className='slider-text'>

<Slide

activeIndex={this.state.activeIndex}

/>

</div>

<RightArrow

goToNextSlide={() => this.goToNextSlide()}

/>

</div>

</div>

);

}

 

The final component required is for the date of the slides. This competent will access the data of the individual slides and display them on the screen of the browser. This particular component will return a function that can display the information of the array.

class Slide extends Component {

 constructor(props) {

   super(props);

   this.state = {landing: landingData};

 }render() {

   return(

     <section>

     {

       this.state.landing.map((s, index) =>

         <div className={

           index === this.props.activeIndex ? 'active' : 'slide'}

           key={index}>

             <h1>{s.title}</h1>

             <p>{s.description}</p>

         </div>

       ) }

       </section>

   )

 }

}export default Slide;

 

3. Attach CSS to the Carousel

The final step is to insert CSS in the Carousel. Without this, the Carousel will look very messed up. You will see all the slides at once to avoid this; you will have to display the active slides only. For this, create a class that will consist of the activeindex state to specify the index of the active slide.

className={index === this.props.activeIndex ? 'active' : 'inactive'} 

.inactive {

 display: none;

}.active {

 display: block;

}

 

In the above CSS file, only the active index slides are shown, and the inactive are kept hidden. This arranges the slides in an organized mode to avoid confusion.
