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 🙏

介绍

resso,世界上最简单的 React 状态管理器 →

特性

  • 非常简单 🪩
  • 非常聪明 🫙
  • 非常小巧 🫧

安装

pnpm add resso
# or
yarn add resso
# or
npm i resso

使用

import resso from 'resso';

const store = resso({
  count: 0,
  text: 'hello',
  inc() {
    const { count } = store; // 须在顶层解构(若在方法中用到)
    store.count = count + 1;
  },
});

function App() {
  const { count } = store; // 须在顶层解构(若在 UI 中用到)

  return (
    <>
      {count}
      <button onClick={() => (store.count += 1)}>+</button>
    </>
  );
}

* 顶部解构其实是调用 useState(Hooks 规则,否则将有 React 报错)

Edit resso

API

更新单个

store.count = 60;

store('count', (c) => c + 1);

更新多个

store({
  count: 60,
  text: 'world',
});

store((s) => ({
  count: s.count + 1,
  text: s.text === 'hello' ? 'world' : 'hello',
}));

非 state 变量 (Refs)

事实上它与 resso 无关,只是 JavaScript。你可以这样做:

// store.js
export const refs = {
  total: 0,
};

// App.js
import store, { refs } from './store';

* react<18 批量更新

resso.config({ batch: ReactDOM.unstable_batchedUpdates }); // 在项目入口

按需 re-render

// 没有 text 更新,绝不 re-render
function Text() {
  const { text } = store;
  return <p>{text}</p>;
}

// 只在 count 更新时 re-render
function Count() {
  const { count } = store;
  return <p>{count}</p>;
}

// 没有 state 在 UI 中,绝不 re-render
function Control() {
  return (
    <>
      <button onClick={store.inc}>+</button>
      <button onClick={() => (store.count -= 1)}>-</button>
    </>
  );
}
