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 🙏

基于react库,对在可视区一定范围外的dom进行回收的组件

综述

在可视区上下各一屏区间外的元素将会自动回收,随着滚动亦将会及时自动回显。

使用

import React, { useState } from 'react';
import { createRoot } from 'react-dom/client';
// 可通过以下方法导入
import { Recycle, RecycleItem } from 'water-design-recycle';
// import Recycle from 'water-design-recycle';
// const { RecycleItem } = Recycle;

const getData = (index = 1) => {
  return new Array(index)
    .fill(new Array(10).fill(1).map((node, index) => index))
    .reduce((current, item) => {
      return [...current, ...item];
    }, []);
};

const App: React.FC = () => {
  const [list, setList] = useState<number[]>(getData());

  React.useEffect(() => {
    const handleScroll = () => {
      const distantBottom = Math.abs(
        document.documentElement.offsetHeight -
          document.documentElement.clientHeight -
          window.scrollY
      );

      if (distantBottom < 1) {
        // 触底
        setList((prev) => [...prev, ...getData()]);
      }
    };
    window.addEventListener('scroll', handleScroll);
    return () => window.removeEventListener('scroll', handleScroll);
  }, []);

  return (
    <Recycle>
      {list.map((item, index) => (
        <RecycleItem key={index} style={{ height: 350, marginBottom: '20px' }}>
          <div style={{ height: 350, backgroundColor: 'skyblue' }}>{index}</div>
        </RecycleItem>
      ))}
    </Recycle>
  );
};
const root = createRoot(document.getElementById('root')!);
root.render(<App />);

Recycle API

| 参数 | 说明 | 类型 | 默认值 | 版本 | | :------------- | :------- | :------- | :----- | :--- | | throttleTime | 节流时间 | number | 60 | |

RecycleItem API

| 参数 | 说明 | 类型 | 默认值 | 版本 | | :-------------------- | :---------------------------------------------------------------------------------------------------------------------------------------------------- | :-------------------- | :----- | :--- | | className | 自定义类名 | string | - | | | style | 自定义行内样式 | React.CSSProperties | - | | | itemEstimatedHeight | 每一项的 item 占位高度,单位:px,主要是当 item 高度都一样时,可以不需要先渲染出每一项 item 后去拿高度,节省 dom 渲染计算时间,若不传则会自动去拿高度 | number | - | |

注意

若是在 item 项 children 里设置 margin,由于 wrapper 拿不到包含子项和 margin 值,会导致滚动后拿到的 height 不含 margin,因此若需设置 margin,则在 RecycleItem 以样式属性传入即可。
