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 🙏

特性

将组件渲染到组件的其他位置 实现类似 h5 position:'fixed'效果

安装

npm

npm i react-native-portal-view -S

组件

PortalProvider

提供一个根节点,可以处于组件树种任何位置,

Props

| 名称 | 默认值 | 类型 | 描述 |

| -------- | :----: | :----------------: | :------------------- |

| children | void | React.ReactNode | children | | store | DefaultStore | PortalStore | PortalStore 存储了所有的 PortalUpdater |

Portal

包裹的组件会被渲染到根节点下

Props

| 名称 | 默认值 | 类型 | 描述 | | -------- | :----: | :-------------: | :----- | | children | void | React.ReactNode | 子组件 | | namespace | '' | string | 命名空间 |

PortalStore

getUpdater: (namespace?: string) => PortalUpdater

返回指定的 PortalUpdater 示例,不存在会创建一个

PortalUpdater

提供一组方法用于使用函数的方式创建 Portal,添加的组件会渲染到 PortalProvider 中 使用前要在组件树中添加 PortalProvider

setContainer: (componentOrElement: React.ComponentType | React.ReactElement) => void

添加一个容器,例如 react-redux 的 Provider 等; 所有使用 add 方法添加的组件都会渲染到这个容器中

add: (element: React.ReactElement) => string

添加一个组件,并且返回一个 key,这个 key 用于后续的删除及更新操作

update: (key: string, element: React.ReactElement) => void

更新指定的组件

remove: (key: string) => void;

删除指定组件

示例

import * as React from 'react';
import { View, Text, AppRegistry } from 'react-native';
import { PortalProvider,Portal, DefaultStore } from 'react-native-portal-view';
import useToggle from 'react-use/lib/useToggle';

DefaultStore.getUpdater('default').setContainer(props => (
  <View
    {...props}
    pointerEvents="box-none"
    style={[props.style, StyleSheet.absoluteFill, { backgroundColor: 'pink' }]}
  />
));

// PortalStore.getUpdater('default').setContainer(
//   <View pointerEvents="box-none" style={[StyleSheet.absoluteFill, { backgroundColor: 'pink' }]} />,
// );

function Modal(props) {
  return (
    <View style={styles.container}>
      <Text onPress={props.onPress} style={styles.text}>
        Portal example {props.text}, click to destroy
      </Text>
    </View>
  );
}


function App() {
  const [visible, toggle] = useToggle(false);
  const portalKeyRef = React.useRef<string>();

  const onPress = () => {
    if (!portalKeyRef.current) {
      portalKeyRef.current = DefaultStore.getUpdater('default').add(
        <Modal onPress={onPress} text="component modal use PortalStore" />,
      );
    } else {
        DefaultStore.getUpdater('default').remove(portalKeyRef.current);
      portalKeyRef.current = undefined;
    }
  };

  return (
    <>
      <View style={styles.container}>
        <Text onPress={toggle}> {visible ? '销毁' : '创建'} 使用 Portal 组件</Text>
        <Text onPress={onPress}> 创建 使用 PortalStore 静态调用</Text>
      </View>
      {visible && (
        <Portal>
          <Modal onPress={toggle} text="component modal use createPortal" />
        </Portal>
      )}
    </>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
  },
});

AppRegistry.registerComponent('example', () => App);
