[WEB] Having another onPress handler Component makes swiping absurd

react-native-web-swiper

Simple swiper / slider. Works both on React-Native and React-Native-Web.

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, activeIndex, isActive, onPress }) => <Text onPress={onPress}>Your Custom Dot {activeIndex+1}/{index+1}</Text>
  }}
>
  <View style={{ flex: 1 }} /> {/* Slide 1 */}
  <View style={{ flex: 1 }} /> {/* Slide 2 */}
  {/* ... */}
</Swiper>

Dynamic content

The slide automatically gets props.isActive, 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}{props.isActive ? ' (active)' : ''}</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

Prop	Default	Type	Description
vertical	`false`	`boolean`	Swiper vertical layout
from	`0`	`number`	Initial slide index
loop	`false`	`boolean`	Set to `true` to enable continuous loop mode
timeout	`0`	`number`	Delay between auto play transitions (in second). Set negative value for reverse autoplay 😆. Autoplay disabled by default
gesturesEnabled	`() => true`	`function`	Function that returns boolean value. Must return `false` to disable swiping mechanism. Does not disable Prev / Next buttons
springConfig		`Animated.spring`	Tune spring animation on autoplay, touch release or slides changes via buttons
minDistanceToCapture	`5`	`number`	Initiate animation after swipe this distance. It fix gesture collisions inside ScrollView
minDistanceForAction	`0.2`	`number`	Minimal part of swiper width (or height for vertical) must be swiped for changing index. Otherwise animation restore current slide. Default value 0.2 means that 20% must be swiped for change index
positionFixed	`false`	`boolean`	Swiper inner container position `fixed` instead `relative`. Fix mobile safari vertical bounce
containerStyle		`ViewPropTypes.style`	Outer (root) container style
innerContainerStyle		`ViewPropTypes.style`	Inner container style
swipeAreaStyle		`ViewPropTypes.style`	Swipe area style
slideWrapperStyle		`ViewPropTypes.style`	Each slide wrapper style
controlsEnabled	`true`	`boolean`	Dots and control buttons visible and enabled
Controls		`React.Component`	Custom controls component
onAnimationStart		`function`	Any swiper animation start
onAnimationEnd		`function`	Any swiper animation end
onIndexChanged		`function`	Called when active index changed
controlsProps		`object`	see below

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 */}
    }
  }}
/>

Prop	Default	Type	Description
cellsStyle		`object`	Controls corners placeholders styles. Allowed keys is: `top-left`, `top`, `top-right`, `left`, `center`, `right`, `bottom-left`, `bottom` and `bottom-right`, allowed values is `ViewPropTypes.style`
cellsContent		`object`	Controls corners placeholders additional content. Allowed keys is: `top-left`, `top`, `top-right`, `left`, `center`, `right`, `bottom-left`, `bottom` and `bottom-right`, allowed values is `string` OR `React element`
dotsPos	`'bottom'` OR `'right'` if vertical	`boolean` OR `enum('top-left', 'top', 'top-right', 'left', 'center', 'right', 'bottom-left', 'bottom', 'bottom-right')`	Dots position
prevPos	`'bottom-left'` OR `'top-right'` if vertical	`boolean` OR `enum('top-left', 'top', 'top-right', 'left', 'center', 'right', 'bottom-left', 'bottom', 'bottom-right')`	Prev button position
nextPos	`'bottom-right'`	`boolean` OR `enum('top-left', 'top', 'top-right', 'left', 'center', 'right', 'bottom-left', 'bottom', 'bottom-right')`	Next button position
prevTitle	`'Prev'`	`string`	Prev button title
nextTitle	`'Next'`	`string`	Next button title
prevTitleStyle		`Text.propTypes.style`	Customize prev button title
nextTitleStyle		`Text.propTypes.style`	Customize next button title
PrevComponent		`React.Component`	Custom prev button component
NextComponent		`React.Component`	Custom next button component
firstPrevElement		`element`	Custom prev element on first slide (if not loop)
lastNextElement		`element`	Custom next element on last slide (if not loop)
dotsTouchable	`false`	`boolean`	Touches over dots will move swiper to relative slide
dotsWrapperStyle		`ViewPropTypes.style`	Dots wrapper View style
dotProps		`object`	`react-native-elements` Badge props
dotActiveStyle		`object`	Additional style to active dot. Will be added to dot badgeStyle
DotComponent		`React.Component`	Custom dot component

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();
};
