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 🙏

工具介绍

Select - 多值选择类

有一类枚举在多个场景下展示不同的值,比如:后端定义一类服务,包含多种类型。不同类型对应不同的值,是枚举类型。但在前端可能还需要添加类型的名称,描述等。 一个对象才能构成枚举的一个值,这个类就是用于处理这种场景下多值枚举的取值。 代码实例如下:

import {Select} from '@redchili/toolkit';

const fruits = [
  {
    iid: 0, // 数组 index 显式表达为 iid
    desc: '苹果', // 前端展示的描述值
    endValue: 1, // 后端值
  },
  {
    iid: 1,
    desc: '橘子',
    endValue: 2,
  },
  {
    iid: 2,
    desc: '桃花',
    endValue: 3,
  },
];
const fruits = new Select(fruits);

// 获取所有的 desc ,返回数组
fruits.vals('desc'); // ['苹果', '橘子', '桃花']

// 根据特定的 kev-val 获取子项
fruitsEnum.item('iid',1); // {iid:1, desc: '橘子',
    endValue: 2,}

css - 使用 css 语法书写 React.CSSProperties

() => {
  return (
    <div
      style={css`
        min-width: 100px;
        display: flex;
        justify-align: center;
      `}
    ></div>
  );
};

checkImgExists - 判断图片链接地址是否有效

返回 Promise<boolean>


checkImgExists('http://xxx.xxx/xxx').then(res => if (res) console.log('图片地址有效,且宽高不为0'))

moveElement - 将数组里的值先前或向后移动位数

const arr = [1, 2, 3, 4];
const newArr = moveElement(arr, 1); // 数组右移一位
// output [4,1,2,3]
moveElement(arr, -1); // 数组左移一位
// output [2, 3, 4, 1]
