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 🙏

更轻的管理状态插件

Readme

基于js的proxy属性开发的一个插件,处理前端应用中的公共数据状态。

  • 介绍

不依赖任何外部库也无关开发模式,核心是利用proxy的代理特性进行数据代理,监听对象状态变更返回回调,类似vue2源码中的数据劫持依赖收集。

兼容性同 Proxy

使用方式(以vue项目为例)

  • 安装
pnpm i @akar/proxy-property 或 npm i @akar/proxy-property
  • 引入
/** store/index.ts */ 

import moon from '@akar/proxy-property'

const state = {
    todo : {
        github_account: 'kabudaaixuexi'
    }
}

export default moon(
    state,
    {
        usePersisted: false // 是否做session缓存
    }
)
  • 组件内使用
import moon from '@/store'

moon.getState('todo') // kabudaaixuexi

moon.watch('todo',(newVal,oldVal)=>{
    console.log(newVal) // { github_account: 'akar' }
    console.log(oldVal) // { github_account: 'kabudaaixuexi' } 
}, false) // 是否初始化时调用

moon.setState({
    github_account: 'akar'
}, 'todo')
  • 建议

@akar/proxy-property是一个小型的工具函数,代码简单,实现了单项数据流对数据的代理监控,只关心数据层,所以当涉及到视图层的时候需要利用watch函数主动更新视图。可以尝试在项目中使用。
