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 🙏

初衷

23年3月底离职了,本想回到老家找一份远程工作的机会、事与愿违~.

闲之无聊、灵光炸现, 想自己实现一个不一样的react.

95% 以上的场景都是在做 web开发, 不想在引入一个Fiber层 状态驻留用 generator, 后序递归遍历也简单的很

希望大家一起学习、也能给您提供思路。

只有函数组件奥、 内置dom元素(svg 家族暂未处理)

组件就是一个函数, 包含固定参数

function App(
	props,
	oldProps,
	{ instance, useEffect, useState, useSyncExternalStore }
) {
	let [state, setState] = useState('');

	if (true) {
		return <div>布拉布拉</div>;
	}
	return <ABC />;
}

已实现的功能

  • Fragment
  • 子元素数组
  • useState
  • useEffect
  • useSyncExternalStore
  • 批处理更新
  • 元素事件回调 (Once|Passive|Capture) 例: onClickOnce={}
  • onInput 中文输入合成判断
  • KeepAlive (任何组件,)
  • Portal (Fragment 带 target 属性) 没必要多引入一个组件

特点

源码特别少, 700 多行吧, 常规功能基本满足

状态保留使用 generator(天然支持状态保留)

体验

pnpm run demo 直接看源码
