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 🙏

Readme

@React


延迟加载React组件,适用于PC和Mobile端。

安装

$ npm install lr-react-lazy-render

使用说明

在一个页面很长的时候,为了优化首屏的加载效率,可以使用@React这个组件对你原有的组件进行一层包装,他就会在还没有出现在屏幕可视区域之前不会加载你的组件

例如:

import AsyncPainter from "lr-react-lazy-render";

function App() {
 return (<div>
  你的组件
 </div>);
}

export default AsyncPainter({
  TargetComponent: App
});

组件参数

|接口|是否必传|类型|默认|说明| |----|----|----|----|----| |TargetComponent|是|ReactComponent|null|你那个需要异步加载的组件| |distance|否|number|0|当你那个组件距离可视区域多远距离时候开始加载| |placeholderStyle|否|object|看下面|当你那个组件还没有加载之前,默认会预先加载一个站位组件,这个组件必须设置一个高度才有效果,默认高度200px,如果要改变就在这个字段里设置样式即可| |CustomPlaceholder|否|ReactComponent|空div元素|如果你对默认展位组件不满意,你可以通过这个字段自定义占位组件|

placeholderStyle默认:

{
  minHeight: '200px',
  background: '#f9f8f9',
  borderRadius: 8,
  marginBottom: '10px',
}
