Quick start

import React from 'react';
import AliceCarousel from 'react-alice-carousel';
import "react-alice-carousel/lib/alice-carousel.css";

const Gallery = () => {
  const handleOnDragStart = e => e.preventDefault()
  return (
    <AliceCarousel mouseDragEnabled >
      <img src="/img1" onDragStart={handleOnDragStart} className="yours-custom-class" />
      <img src="/img2" onDragStart={handleOnDragStart} className="yours-custom-class" />
      <img src="/img3" onDragStart={handleOnDragStart} className="yours-custom-class" />
      <img src="/img4" onDragStart={handleOnDragStart} className="yours-custom-class" />
      <img src="/img5" onDragStart={handleOnDragStart} className="yours-custom-class" />
    </AliceCarousel>
  )
}

Advanced configuration

Props

• items : Array, default [] - gallery items, preferable to use this property instead of children

• duration : Number, default 250 - Duration of slides transition (milliseconds)

• responsive : Object, default {} - Number of items in the slide

    {
        0: {
            items: 1
        },
        1024: {
            items: 3
        }
    }

• stagePadding : Object, default {} - Padding left and right on the stage

    {
        paddingLeft: 0,     // in pixels
        paddingRight: 0
    }

• buttonsDisabled : Boolean, false - Disable buttons control

• dotsDisabled : Boolean, false - Disable dots navigation

• startIndex : Number, 0 - The starting index of the carousel

• slideToIndex : Number, 0 - Sets the carousel at the specified position

• swipeDisabled : Boolean, default false - Disable swipe handlers

• mouseDragEnabled : Boolean, default false - Enable mouse drag animation

  To Avoid unexpected behavior you should handle drag event independently, something like in an example

• infinite : Boolean, default true - Disable infinite mode

• fadeOutAnimation : Boolean, false - Enable fadeout animation. Fired when 1 item is in the slide

• keysControlDisabled : Boolean, default false - Disable keys controls (left, right, space)

• playButtonEnabled : Boolean, default false - Disable play/pause button

• autoPlay : Boolean, default false - Set auto play mode

• autoPlayInterval : Number, default 250 - Interval of auto play animation (milliseconds). If specified, a larger value will be taken from comparing this property and the duration one

• autoPlayDirection : String, default ltr - To run auto play in the left direction specify rtl value

• disableAutoPlayOnAction : Boolean, default false - If this property is identified as true auto play animation will be stopped after clicking user on any gallery button

• stopAutoPlayOnHover : Boolean, default true - If this property is identified as false auto play animation won't stopped on hover

• showSlideInfo : Boolean, default false - Show slide info

• preventEventOnTouchMove : Boolean, default false - Prevent the browser's touchmove event when carousel is swiping

• onSlideChange : Function - Fired when the event object is changing / returns event object

• onSlideChanged : Function - Fired when the event object was changed / returns event object

• onInitialized : Function - Fired when the gallery was initialized / returns event object

• onResized : Function - Fired when the gallery was resized / returns event object

  All functions return the next object

    {
        item: index,   // index of the current item`s position
        slide: index   // index of the current slide`s position
        itemsInSlide: number   // number of elements in the slide
    }

Examples

import React from 'react'
import AliceCarousel from 'react-alice-carousel'
import "react-alice-carousel/lib/alice-carousel.css"

class Gallery extends React.Component {
  state = {
    galleryItems: [1, 2, 3].map((i) => (<h2 key={i}>{i}</h2>)),
  }

  responsive = {
    0: { items: 1 },
    1024: { items: 2 },
  }

  onSlideChange(e) {
    console.debug('Item`s position during a change: ', e.item)
    console.debug('Slide`s position during a change: ', e.slide)
  }

  onSlideChanged(e) {
    console.debug('Item`s position after changes: ', e.item)
    console.debug('Slide`s position after changes: ', e.slide)
  }

  render() {
    return (
      <AliceCarousel
        items={this.state.galleryItems}
        responsive={this.responsive}
        autoPlayInterval={2000}
        autoPlayDirection="rtl"
        autoPlay={true}
        fadeOutAnimation={true}
        mouseDragEnabled={true}
        playButtonEnabled={true}
        disableAutoPlayOnAction={true}
        onSlideChange={this.onSlideChange}
        onSlideChanged={this.onSlideChanged}
      />
    )
  }
}

Custom Prev / Next buttons, dots / thumbs navigation:

• Using - refs.

import React from 'react'
import AliceCarousel from 'react-alice-carousel'
import "react-alice-carousel/lib/alice-carousel.css"

class Gallery extends React.Component {  
  items = [1, 2, 3, 4, 5]

  state = {
    galleryItems: this.items.map((i) => (<h2 key={i}>{i}</h2>))
  }

  thumbItem = (item, i) => (
    <span key={item} onClick={() => this.Carousel._onDotClick(i)}>* </span>
  )

  render() {
    return (
      <div>
        <AliceCarousel
          dotsDisabled={true}
          buttonsDisabled={true}
          items={this.state.galleryItems}
          ref={(el) => (this.Carousel = el)}
        />

        <nav>{this.items.map(this.thumbItem)}</nav>
        <button onClick={() => this.Carousel._slidePrev()}>Prev button</button>
        <button onClick={() => this.Carousel._slideNext()}>Next button</button>
      </div>
    )
  }
}

• Using props

import React from 'react'
import AliceCarousel from 'react-alice-carousel'
import "react-alice-carousel/lib/alice-carousel.css"

class Gallery extends React.Component {
  items = [1, 2, 3, 4, 5]

  state = {
    currentIndex: 0,
    responsive: { 1024: { items: 3 } },
    galleryItems: this.galleryItems(),
  }

  slideTo = (i) => this.setState({ currentIndex: i })

  onSlideChanged = (e) => this.setState({ currentIndex: e.item })

  slideNext = () => this.setState({ currentIndex: this.state.currentIndex + 1 })

  slidePrev = () => this.setState({ currentIndex: this.state.currentIndex - 1 })

  thumbItem = (item, i) => <span onClick={() => this.slideTo(i)}>* </span>

  galleryItems() {
    return this.items.map((i) => <h2 key={i}> {i}</h2>)
  }

  render() {
    const { galleryItems, responsive, currentIndex } = this.state
    return (
      <div>
        <AliceCarousel
          dotsDisabled={true}
          buttonsDisabled={true}
          items={galleryItems}
          responsive={responsive}
          slideToIndex={currentIndex}
          onSlideChanged={this.onSlideChanged}
        />

        <ul>{this.items.map(this.thumbItem)}</ul>
        <button onClick={() => this.slidePrev()}>Prev button</button>
        <button onClick={() => this.slideNext()}>Next button</button>
      </div>
    )
  }
}

Example for slidePrev/slideNext page

import React from 'react'
import AliceCarousel from 'react-alice-carousel'
import 'react-alice-carousel/lib/alice-carousel.css'

class Gallery extends React.Component {
  state = {
    currentIndex: 0,
    itemsInSlide: 1,
    responsive: { 0: { items: 3 }},
    galleryItems: this.galleryItems(),
  }

  galleryItems() {
    return (
      Array(7).fill().map((item, i) => <h2 className="item">{i + 1}</h2>)
    )
  }

  slidePrevPage = () => {
    const currentIndex = this.state.currentIndex - this.state.itemsInSlide
    this.setState({ currentIndex })
  }

  slideNextPage = () => {
    const { itemsInSlide, galleryItems: { length }} = this.state
    let currentIndex = this.state.currentIndex + itemsInSlide
    if (currentIndex > length) currentIndex = length

    this.setState({ currentIndex })
  }

  handleOnSlideChange = (event) => {
    const { itemsInSlide, item } = event
    this.setState({ itemsInSlide, currentIndex: item })
  }

  render() {
    const { currentIndex, galleryItems, responsive } = this.state

    return (
      <div>
        <AliceCarousel
          items={galleryItems}
          slideToIndex={currentIndex}
          responsive={responsive}
          onInitialized={this.handleOnSlideChange}
          onSlideChanged={this.handleOnSlideChange}
          onResized={this.handleOnSlideChange}
        />
        <button onClick={this.slidePrevPage}>Prev Page</button>
        <button onClick={this.slideNextPage}>Next Page</button>
      </div>
    )
  }
}
