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-iscroller

react 的无限滚动方案

安装

npm i react-iscroller

使用

import { InfiniteScroller } from "react-iscroller"

return <InfiniteScroller
  itemAverageHeight={22}
  containerHeight={window.innerHeight}
  items={this.state.messages}
  itemKey="id"
  onRenderCell={this.renderCell}/>

props

containerHeight(required): number

scroller 的高度

items(required): any[]

你的数据

itemKey(required): string

item 的 id。 使用 itemKey 帮助 react 实现 pure component。

itemAverageHeight(required): number

如果你的 item 高度都相同那这里就填 item 的高度。如果是动态高度,尽量输入最平均的那个高度,如果还是没法确定,直接用 item 的最小高度。平均高度不影响 scroller 运行,只会影响显示数量。

onRenderCell(required): (item: any, index: number) => ReactNode

当每条 item 渲染的时候会调用这个函数

cache(optional): Cache[]

如果需要看到哪回到哪的功能,你必须用你的状态管理保存缓存。如果不填,不影响 scroller 正常运行。

initialScrollTop(optional): number

再组件加载的时候滑动到 initialScrollTop 指定的位置。一般配合缓存滑动到上次看到的位置。如果不提供缓存也可以,但是位置是猜测的。

onScroll(optional): (scrollerDom: HTMLDivElement) => void

滑动的时候会调用此函数,可以从这个函数里拿到 scroller 的原生 dom.

onEnd?: () => void

滑动到底部的时候会触发此函数,可以在这里更新数据
