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 🙏

import { React } from 'react'

const App = props => {
    return (
      <div>
        {serverData 
            && serverData.producList 
            && serverData.producList[0] 
            && serverData.producList[0].price 
            && ( <div>{`the price is ${serverData.producList[0].price}`}</div>
        )}
      </div>
    )
}

如果你不想再写出这样的代码,可以来试试 safer。

使用 safer 可以安心读写对象的属性和值,让开发者将精力集中在代码逻辑上,引入 safer 并包裹在想要读写的对象外层,即可安全使用。 当获取/赋予的属性不存在时,程序并不会崩溃白屏,可以减少开发者为了“保证程序健壮性”而加入的层层判断的冗余代码。

NOTE: safer 使用了 Proxy 的特性来实现安全读写功能,如果浏览器环境不支持 Proxy,可以使用 proxy-polyfill

safer 也支持方法的调用。如果对象中的方法不一定存在,那么也可以使用 safer 包裹在外层,安心调用

install

npm install jerrys-safer --save
