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 🙏

yann-useState

使用

import { useState } from 'yann-usestate';
// state 是一个vue的ref对象
// setState 是赋值state的函数
const [state, setState] = useState(false);

// 如果需要做数据比对
const [state, setState] = useState(false, {
  // 如果开启diff,默认会采用内置拷贝的方式进行深拷贝
  diff: true
});

//比对函数默认采用的是lodash的isEqual,也可以自定义一个比较函数
const [state, setState] = useState(false, {
  diff: true,
  diffEvent(newVal, oldVal) {
    // 返回 true 表示两个值相同,不会重新赋值
    return isEqual(newVal, oldVal);
  }
});

// 如果你需要对赋值函数做一定的处理,那么你还可以设定 setStateEvent 函数
const [state, setState] = useState(false, {
  // 他将在diff执行之后触发
  setStateEvent(newVal) {
    // 你需要将要赋值的内容进行返回
    // 例如你需要做深拷贝,你可以使用 lodash的 cloneDeep
    return cloneDeep(newVal);
  }
});

// 如果你想知道开启 diff 后 setState 两个值是否相等可以通过 setState 函数的放回值确定,返回 true 表示两个值相等并且不会执行赋值操作,返回false表示不相等会进行赋值操作,(仅在diff开启的情况下是有效的)
