Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

react-native-pager-view

npm package Lean Core Extracted License

Lint iOS Build Android Build

This component allows the user to swipe left and right through pages of data. Under the hood it is using the native Android ViewPager and the iOS UIPageViewController implementations. See it in action!

Versions

| 4.x | 5.x and above | | ---------- | ------------- | | iOS | iOS support | | ViewPager1 | ViewPager2 |

Migration

In version 6.x support for transitionStyle property has been dropped. More information here.

"@react-native-community/viewpager" library has been changed to react-native-pager-view. Here you can find more information, how to migrate pager view to the latest version

Getting started

yarn add react-native-pager-view

Linking

>= 0.60

Autolinking will just do the job.

< 0.60

Mostly automatic

react-native link react-native-pager-view

Manual linking

Follow the instructions in the React Native documentation to manually link the framework or link using Cocoapods by adding this to your Podfile:

pod 'react-native-pager-view', :path => '../node_modules/react-native-pager-view'

android/settings.gradle

include ':react-native-pager-view'
project(':react-native-pager-view').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-pager-view/android')

android/app/build.gradle

dependencies {
   ...
   implementation project(':react-native-pager-view')
}

android/app/src/main/.../MainApplication.java

On top, where imports are:

Add import com.reactnativepagerview.PagerViewPackage;

Add the PagerViewPackage class to your list of exported packages.

@Override
protected List<ReactPackage> getPackages() {
  return Arrays.<ReactPackage>asList(
    new MainReactPackage(),
    new PagerViewPackage()
  );
}

Usage

import React from 'react';
import { StyleSheet, View, Text } from 'react-native';
import PagerView from 'react-native-pager-view';

const MyPager = () => {
  return (
    <PagerView style={styles.pagerView} initialPage={0}>
      <View key="1">
        <Text>First page</Text>
      </View>
      <View key="2">
        <Text>Second page</Text>
      </View>
    </PagerView>
  );
};

const styles = StyleSheet.create({
  pagerView: {
    flex: 1,
  },
});

Attention: Note that you can only use View components as children of PagerView (cf. folder /example) . For Android if View has own children, set prop collapsable to false https://reactnative.dev/docs/view#collapsable-android, otherwise react-native might remove those children views and and its children will be rendered as separate pages

Advanced usage

For advanced usage please take a look into our example project

API

| Prop | Description | Platform | | -------------------------------------------------------------------- | :-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------: | :------: | | initialPage | Index of initial page that should be selected | both | | scrollEnabled: boolean | Should pager view scroll, when scroll enabled | both | | onPageScroll: (e: PageScrollEvent) => void | Executed when transitioning between pages (ether because the animation for the requested page has changed or when the user is swiping/dragging between pages) | both | | onPageScrollStateChanged: (e: PageScrollStateChangedEvent) => void | Function called when the page scrolling state has changed | both | | onPageSelected: (e: PageSelectedEvent) => void | This callback will be called once the ViewPager finishes navigating to the selected page | both | | pageMargin: number | Blank space to be shown between pages | both | | keyboardDismissMode: ('none' / 'on-drag') | Determines whether the keyboard gets dismissed in response to a drag | both | | orientation: Orientation | Set horizontal or vertical scrolling orientation (it does not work dynamically) | both | | overScrollMode: OverScrollMode | Used to override default value of overScroll mode. Can be auto, always or never. Defaults to auto | Android | | offscreenPageLimit: number | Set the number of pages that should be retained to either side of the currently visible page(s). Pages beyond this limit will be recreated from the adapter when needed. Defaults to RecyclerView's caching strategy. The given value must either be larger than 0. | Android | | overdrag: boolean | Allows for overscrolling after reaching the end or very beginning or pages. Defaults to false | iOS | | layoutDirection: ('ltr' / 'rtl' / 'locale') | Specifies layout direction. Use ltr or rtl to set explicitly or locale to deduce from the default language script of a locale. Defaults to locale | both |

| Method | Description | Platform | | ------------------------------------------ | :--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------: | :------: | | setPage(index: number) | Function to scroll to a specific page in the PagerView. Invalid index is ignored. | both | | setPageWithoutAnimation(index: number) | Function to scroll to a specific page in the PagerView. Invalid index is ignored. | both | | setScrollEnabled(scrollEnabled: boolean) | A helper function to enable/disable scroll imperatively. The recommended way is using the scrollEnabled prop, however, there might be a case where a imperative solution is more useful (e.g. for not blocking an animation) | both |

Known Issues

  • flex:1 does not work for child views, please use width: '100%', height: '100%' instead

  • [iOS]: In case of UIViewControllerHierarchyInconsistency error, please use below fix:

requestAnimationFrame(() => refPagerView.current?.setPage(index));

Reanimated onPageScroll handler

An example can be found here

Instructions

To attach reanimated handler with onPageScroll follow the below steps.

// 1. Define the handler
function usePageScrollHandler(handlers, dependencies) {
  const { context, doDependenciesDiffer } = useHandler(handlers, dependencies);
  const subscribeForEvents = ['onPageScroll'];

  return useEvent(
    (event) => {
      'worklet';
      const { onPageScroll } = handlers;
      if (onPageScroll && event.eventName.endsWith('onPageScroll')) {
        onPageScroll(event, context);
      }
    },
    subscribeForEvents,
    doDependenciesDiffer
  );
}

// 2. Attach the event handler
import PagerView from 'react-native-pager-view';
import Animated from 'react-native-reanimated';
const AnimatedPagerView = Animated.createAnimatedComponent(PagerView);

const pageScrollHandler = usePageScrollHandler({
  onPageScroll: (e) => {
    'worklet';
    offset.value = e.offset;
    console.log(e.offset, e.position);
  },
});

<AnimatedPagerView onPageScroll={pageScrollHandler} />;
