React-Slideshow

A simple slideshow component built with react that supports slide, fade and zoom effects

Installation

npm install react-slideshow-image -S

yarn add react-slideshow-image

You can use three different effects of the slideshow. Check the demo

Slide Effect

import React from 'react';
import { Slide } from 'react-slideshow-image';

const slideImages = [
  'images/slide_2.jpg',
  'images/slide_3.jpg',
  'images/slide_4.jpg'
];

const properties = {
  duration: 5000,
  transitionDuration: 500,
  infinite: true,
  indicators: true,
  arrows: true,
  pauseOnHover: true,
  onChange: (oldIndex, newIndex) => {
    console.log(`slide transition from ${oldIndex} to ${newIndex}`);
  }
}

const Slideshow = () => {
    return (
      <div className="slide-container">
        <Slide {...properties}>
          <div className="each-slide">
            <div style={{'backgroundImage': `url(${slideImages[0]})`}}>
              <span>Slide 1</span>
            </div>
          </div>
          <div className="each-slide">
            <div style={{'backgroundImage': `url(${slideImages[1]})`}}>
              <span>Slide 2</span>
            </div>
          </div>
          <div className="each-slide">
            <div style={{'backgroundImage': `url(${slideImages[2]})`}}>
              <span>Slide 3</span>
            </div>
          </div>
        </Slide>
      </div>
    )
}

The default value for duration and transitionDuration is 5000 and 1000 milliseconds respectively

Fade Effect

import React from 'react';
import { Fade } from 'react-slideshow-image';

const fadeImages = [
  'images/slide_5.jpg',
  'images/slide_6.jpg',
  'images/slide_7.jpg'
];

const fadeProperties = {
  duration: 5000,
  transitionDuration: 500,
  infinite: false,
  indicators: true,
  onChange: (oldIndex, newIndex) => {
    console.log(`fade transition from ${oldIndex} to ${newIndex}`);
  }
}

const Slideshow = () => {
  return (
    <div className="slide-container">
      <Fade {...fadeProperties}>
        <div className="each-fade">
          <div className="image-container">
            <img src={fadeImages[0]} />
          </div>
          <h2>First Slide</h2>
        </div>
        <div className="each-fade">
          <div className="image-container">
            <img src={fadeImages[1]} />
          </div>
          <h2>Second Slide</h2>
        </div>
        <div className="each-fade">
          <div className="image-container">
            <img src={fadeImages[2]} />
          </div>
          <h2>Third Slide</h2>
        </div>
      </Fade>
    </div>
  )
}

The default value for duration and transitionDuration is 5000 and 1000 milliseconds respectively

Zoom Effect

import React from 'react';
import { Zoom } from 'react-slideshow-image';

const images = [
  'images/slide_2.jpg',
  'images/slide_3.jpg',
  'images/slide_4.jpg',
  'images/slide_5.jpg',
  'images/slide_6.jpg',
  'images/slide_7.jpg'
];

const zoomOutProperties = {
  duration: 5000,
  transitionDuration: 500,
  infinite: true,
  indicators: true,
  scale: 0.4,
  arrows: true
}

const Slideshow = () => {
    return (
      <div className="slide-container">
        <Zoom {...zoomOutProperties}>
          {
            images.map((each, index) => <img key={index} style={{width: "100%"}} src={each} />)
          }
        </Zoom>
      </div>
    )
}

Customizing Indciators

The indicator can be customizes to what you want. To customize it, set the indicators prop to a function that returns the element you want. The function accepts an index parameter.

{
  indicators: i => (
    <div
      style={{
        width: '30px',
        color: 'blue',
        textAlign: 'center',
        cursor: 'pointer',
        border: '1px blue solid'
      }}
    >
      {i + 1}
    </div>
  )
),

CSS

This is what my css looks like. You can customize this to your own taste

.slide-container {
  width: 70%;
  margin: auto; }

h3 {
  text-align: center; }

.each-slide > div {
  display: flex;
  align-items: center;
  justify-content: center;
  background-size: cover;
  height: 300px;
}

.each-slide span {
  padding: 20px;
  font-size: 20px;
  background: #efefef;
  text-align: center;
}

.each-fade {
  display: flex;
}

.each-fade .image-container {
  width: 75%;
  overflow: hidden;
}

.each-fade .image-container img {
  width: 100%;
}

.each-fade h2 {
  width: 25%;
  display: flex;
  justify-content: center;
  align-items: center;
  margin: 0;
  background: #adceed;
}

Next

⚠️ For those using Next.js . You need the import the package dynamically and set ssr property to false. The snippet below imports the Fade effect

import dynamic from 'next/dynamic';
const Fade = dynamic(() =>
  import('react-slideshow-image').then((slideshow) => slideshow.Fade),
  { ssr: false }
)

HTML properties like className, data-* attributes and others will be applied to the parent div

Properties

Properties	Type	DefaultValue	Description
duration	integer	5000	Time it takes (milliseconds) before next transition starts
transitionDuration	integer	1000	Determines how long the transition takes
defaultIndex	integer	0	Specifies the first slide to display
infinite	boolean	true	Specifies if the transition should loop throughout
indicators	boolean or function	false	For specifying if there should be dots below the slideshow. If function, it will render the returned element
scale	number		Required when using zoom to specify the scale the current slide should be zoomed to
arrows	boolean	true	Determines if there should be a navigational arrow for going to the next or previous slide
prevArrow	object or function	null	A custom element to serve as previous arrow
nextArrow	object or function	null	A custom element to serve as next arrow
autoplay	boolean	true	Responsible for determining if the slideshow should start automatically
pauseOnHover	boolean	false	Determines whether the transition effect applies when the mouse hovers the slider
onChange	function		Callback that gets triggered at the end of every transition. The oldIndex and newIndex are passed as arguments

Methods

1. goNext() It is used to programmatically transition the slide to the next one.

2. goBack() If you want to show the previous slide, then use this function

3. goTo(index) It can be used to transition the slide to a particular index. N.B Index starts from 0

To call the method you can use the slide's ref attribute and then call the method. this.slideRef.goNext() or this.slideRef.current.goNext()

Typescript

1. In your tsconfig.json file add this to the compiler options

"typeRoots": [
      "./types",
      "./node_modules/@types"
]

1. Create a file in this directory types/react-slideshow-image/index.d.ts
2. Copy and paste this into it

declare module 'react-slideshow-image' {
    export class Zoom extends React.Component<ZoomProps & any, any> {
        goBack(): void;
        goNext(): void;
        goTo(index: number): void;
    }
    export class Fade extends React.Component<SlideshowProps & any, any> {
        goBack(): void;
        goNext(): void;
        goTo(index: number): void;
    }
    export class Slide extends React.Component<SlideshowProps & any, any> {
        goBack(): void;
        goNext(): void;
        goTo(index: number): void;
    }
    export interface SlideshowProps {
        duration?: number,
        transitionDuration?: number,
        defaultIndex?: number,
        indicators?: boolean | function,
        prevArrow?: object | function,
        nextArrow?: object | function,
        arrows?: boolean,
        autoplay?: boolean,
        infinite?: boolean,
        onChange?(oldIndex: number, newIndex: number): void,
        pauseOnHover?: boolean
    }
    export interface ZoomProps extends SlideshowProps {
        scale: number
    }
}
