Installation

$ npm i react-native-web-swiper --save

Usage

import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
import Swiper from 'react-native-web-swiper';

const styles = StyleSheet.create({
  container: {
    flex: 1,
  },
  slideContainer: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
  },
  slide1: {
    backgroundColor: 'rgba(20,20,200,0.3)',
  },
  slide2: {
    backgroundColor: 'rgba(20,200,20,0.3)',
  },
  slide3: {
    backgroundColor: 'rgba(200,20,20,0.3)',
  },
});

export default class Screen extends React.Component {
  render() {
    return (
      <View style={styles.container}>
        <Swiper>
          <View style={[styles.slideContainer,styles.slide1]}>
            <Text>Slide 1</Text>
          </View>
          <View style={[styles.slideContainer,styles.slide2]}>
            <Text>Slide 2</Text>
          </View>
          <View style={[styles.slideContainer,styles.slide3]}>
            <Text>Slide 3</Text>
          </View>
        </Swiper>
      </View>
    );
  }
}

With props

<Swiper
  vertical {/* slide up / down instead left / right */}
  from={1} {/* initial slide is second */}
  loop {/* back to first slide after last */}
  timeout={2} {/* autoplay duration (2 secs) */}
  springConfig={{ speed: 11 }} {/* RN Animated.spring config */}
  minDistanceForAction={0.15} {/* Swipe less that 15% keep active slide */}
  positionFixed {/* Fix mobile safari vertical bounces */}
  controlsProps={{
    DotComponent: ({ index, isActive, onPress }) => <Text onPress={onPress}>Your Custom Dot {index+1}</Text>
  }}
>
  <View style={{ flex: 1 }} /> {/* Slide 1 */}
  <View style={{ flex: 1 }} /> {/* Slide 2 */}
  {/* ... */}
</Swiper>

Dynamic content

The slide automatically gets props.activeIndex and props.index.

import React from 'react';
import { Text, View } from 'react-native';
import Swiper from 'react-native-web-swiper';

type Props = {
  index?: number,
  activeIndex?: number,
}
export const SomeSlide = (props: Props) => (
  <View>
    <Text>{props.activeIndex}/{props.index}</Text>
  </View>
)

export default () => (
  <Swiper>
    <SomeSlide />
    <SomeSlide />
  </Swiper>
)

This is possible because Swiper used cloneElement and inject internally the activeIndex and index props to each slide. This also means that all slides will re-render on swipe, since the activeIndex prop value changes on swipe.

Props

Controls Props

Over the swiper we need to create a controls layer. But this layer will block the possibility of swiper layer control. We created 9 controls placeholders to solve this problem: top-left, top, top-right, left, center, right, bottom-left, bottom and bottom-right. You can adjust controls position by placing into relevant placeholder:

<Swiper
  ...
  controlsProps={{
    prevTitle: 'prev button title',
    nextTitle: 'next button title',
    dotsTouchable: true, {/* touch over dot will make swiper move to rel slide */}
    dotsPos: 'top',
    prevPos: false, {/* hide prev button */}
    nextPos: 'top-right',
    cellsStyle: {
      'top': { padding: 5, backgroundColor: 'rgba(0, 0, 0, .3)' },
      'top-left': { /* any custom placeholder style */ },
    },
    cellsContent: {
      'bottom-right': <AnyComponent /> {/* Additional content in placeholder */}
    }
  }}
/>

Interaction methods

Store a reference to the Swiper in your component by using the ref prop provided by React (see docs):

const swiperRef = useRef(null);

...

<Swiper
  ref={swiperRef}
  ...
/>

Then you can manually trigger swiper from anywhere:

() => {
  swiperRef.current.goTo(1);
  swiperRef.current.goToPrev();
  swiperRef.current.goToNext();
  const index = swiperRef.current.getActiveIndex();
};
