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 🙏

安装

npm i @qse/router-cache

使用

import React from 'react'
import { withCache } from '@qse/router-cache'
import { useRoutes } from 'react-router-dom'

const List = withCache(() => <div>list</div>)
const Item = () => <div>item</div>

const APP_ROUTES = [
  {
    path: '/list',
    element: <List />,
    children: [{ path: ':id', element: <Item /> }],
  },
]

const App = () => useRoutes(APP_ROUTES)

export default App

原理

使用 react-freeze 实现组件冻结

冻结特性

  • 组件无法感知冻结状态,因为在进入冻结状体时,所有 hooks 都停止工作了
  • 冻结状态的组件不会执行 hooks,也不会刷新视图,dom
  • 副作用函数还是会执行,例如 window.addEventListener

解冻特性

  • 组件能够感知解冻状态,可以通过对比解冻前后 Date.now()
  • 解冻后组件会使用最新的数据刷新一遍视图
