How to Add Image Slider with Preview Thumbnails in React js App?

  • Step 1 – Create React App
  • Step 2 – Install React Image Gallery Plugin
  • Step 3 – Create Image Slider Component
  • Step 4 – Import Component in App.js
  • Step 5 – Configuration Props and Settings
  • Step 6 – Run React App

 

Step 1 – Create React App

To start, let’s create a new React Js application. Execute the following command in the terminal window:

npx create-react-app react-demo-app

Then, move inside the application directory:

cd react-demo-app

Step 2 – Install React Image Gallery Plugin

Now, we will install the React Image Gallery package in the react application. Execute the following npm command at application root:

npm install react-image-gallery

Step 3 – Create Image Slider Component

Next, move into the src directory and create a new component named image-slider.component.js file. This will have the Image Slider component which can be used anywhere inside the app.

Update the ~src/image-slider.component.js file with the following code:

import React from "react";
import '../node_modules/react-image-gallery/styles/css/image-gallery.css';
import ImageGallery from 'react-image-gallery';

const images = [
    {
      original: 'https://picsum.photos/id/1018/1000/400/',
      thumbnail: 'https://picsum.photos/id/1018/250/150/',
    },
    {
      original: 'https://picsum.photos/id/1015/1000/400/',
      thumbnail: 'https://picsum.photos/id/1015/250/150/',
    },
    {
      original: 'https://picsum.photos/id/1026/1000/400/',
      thumbnail: 'https://picsum.photos/id/1026/250/150/',
    }
  ];

class ImageSliderComponent extends React.Component {

  render() {
    return (
        <div className="wrapper">
            <ImageGallery items={images} />
        </div>
    );
  }
}
export default ImageSliderComponent;

Step 4 – Import Component in App.js

Now, we will use our ImageSliderComponent in the App.js file which is the main component in a React app. Open the App.js file and update it as shown below:

import './App.css';
import ImageSliderComponent from './image-slider.component';

function App() {
  return (
    <div className="App">
       <h3>React Image Slider with Thumbnails</h3> 
       
       <ImageSliderComponent />

    </div>
  );
}

export default App;

Step 5 – Configuration Props and Settings

Let’s have a look at important props and functions available on the Image Gallery component:

React Image Gallery Functions with Example

The following functions can be accessed using refs

  • play(): plays the slides
  • pause(): pauses the slides
  • fullScreen(): activates the full screen
  • exitFullScreen(): deactivates the full screen
  • slideToIndex(index): slides to a specific index
  • getCurrentIndex(): returns the current index

 

Let’s get into more detail on using some of the functions with examples

import React from "react";
import "../node_modules/react-image-gallery/styles/css/image-gallery.css";
import ImageGallery from "react-image-gallery";

const images = [
  {
    original: "https://picsum.photos/id/1018/1000/400/",
    thumbnail: "https://picsum.photos/id/1018/250/150/",
  },
  {
    original: "https://picsum.photos/id/1015/1000/400/",
    thumbnail: "https://picsum.photos/id/1015/250/150/",
  },
  {
    original: "https://picsum.photos/id/1026/1000/400/",
    thumbnail: "https://picsum.photos/id/1026/250/150/",
  },
];

class ImageSliderComponent extends React.Component {
  constructor(props) {
    super(props);
    this.myImageRef = React.createRef();
    this.onFullscreen = this.onFullscreen.bind(this);
    this.onPlay = this.onPlay.bind(this);
    this.onPause = this.onPause.bind(this);
    this.onMoveToSlide = this.onMoveToSlide.bind(this);
  }

  onFullscreen() {
    this.myImageRef.current.fullScreen()
  }
  onPlay() {
    this.myImageRef.current.play()
  }
  onPause() {
    this.myImageRef.current.pause()
  }
  onMoveToSlide() {
    // Index start from 0 so 2 will move to 3rd slide
    this.myImageRef.current.slideToIndex(2)
  }

  render() {
    return (
      <div className="wrapper">
        <ImageGallery items={images}  ref={this.myImageRef} />
        <button onClick={this.onFullscreen}>FullScreen</button>
        <button onClick={this.onPlay}>Play</button>
        <button onClick={this.onPause}>Pause</button>
        <button onClick={this.onMoveToSlide}>SlideTo 3rd Slide</button>
      </div>
    );
  }
}
export default ImageSliderComponent;

 

Props available in React Image Gallery

There are a large number of props available. We will discuss a few of them over here and discuss how to use them efficiently.

  • items: (required) Array of objects with image URLs.
  • infinite: Enable infinite sliding.
  • lazyLoad: Enable lazy loading of images. useful when loading large size images.
  • autoPlay: This will auto slide images after a specified duration of time.
  • slideDuration: Duration of sliding the images.

Some of the important Events:

  • onSlide: Triggered on sliding the image.
  • onClick: Triggered on slide click.
  • onTouchMove: Triggered on touch move.
class ImageSliderComponent extends React.Component {
  constructor(props) {
    super(props);
    this.myImageRef = React.createRef();
    this.onFullscreen = this.onFullscreen.bind(this);
    this.onPlay = this.onPlay.bind(this);
    this.onPause = this.onPause.bind(this);
    this.onMoveToSlide = this.onMoveToSlide.bind(this);
  }

  onFullscreen() {
    this.myImageRef.current.fullScreen()
  }
  onPlay() {
    this.myImageRef.current.play()
  }
  onPause() {
    this.myImageRef.current.pause()
  }
  onMoveToSlide() {
    // Index start from 0 so 2 will move to 3rd slide
    this.myImageRef.current.slideToIndex(2)
  }

  onEventTrigger(eventName){
    console.log('Event Name ',eventName);
  }

  render() {
    return (
      <div className="wrapper">

        <ImageGallery 
        
        items={images}  
        infinite={true}
        lazyLoad={true}
        autoPlay={true}
        autoPlay={true}
        slideDuration={3000}

        onSlide={() => this.onEventTrigger('onSlide')}
        onClick={() => this.onEventTrigger('onClick')}
        onTouchMove={() => this.onEventTrigger('onTouchMove')}

        ref={this.myImageRef} />

        <button onClick={this.onFullscreen}>FullScreen</button>
        <button onClick={this.onPlay}>Play</button>
        <button onClick={this.onPause}>Pause</button>
        <button onClick={this.onMoveToSlide}>SlideTo 3rd Slide</button>
      </div>
    );
  }
}
export default ImageSliderComponent;
