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 🙏

react useProps 方法,用于智能合并组件入参,方便组件开发

code-review dependency-review Codacy Badge Codacy Badge npm version

特点

  1. Props 类型自动添加 children、style、className 和 HTMLAttributes 入参
  2. 自动合并 style、className
  3. 自动忽略 undefined 入参

使用

组件开发

import useProps, {type Props} from 'use-props';

// 1. 定义组件入参
export type MyCompProps = Props<{
  abc: number;
  def?: number;
  opq?: number;
  xyz?: number;
}>;

// 2. 定义组件默认值
export const myCompDefaults = {
  def: 1,
  opq: 1,
} satisfies Partial<MyCompProps>;

// 3. 实现组件
export default function MyComp(props: MyCompProps) {
  // 4. 合并入参
  const {children, abc, def, opq, xyz, ...attrs} = useProps(props, myCompDefaults);
  // abc 类型为 number
  // def 类型为 number
  // opq 类型为 number
  // xyz 类型为 number | undefined

  return (
    <div {...attrs}>
      abc = {abc}
      def = {def}
      opq = {opq}
      xyz = {xyz}
      {children}
    </div>
  );
}

组件使用

// abc 必填
<MyComp abc={2}/>
// 渲染 abc=2 def=1 opq=1 xyz=undefined

// abc 必填,传入可选 def
<MyComp abc={2} def={2}/>
// 渲染 abc=2 def=2 opq=1 xyz=undefined

// abc 必填,传入可选 def,传入 opq 为 undefined
<MyComp abc={2} def={2} opq={undefined}/>
// 渲染 abc=2 def=2 opq=1 xyz=undefined

// abc 必填,传入可选 def,传入 opq 为 undefined,传入 xyz
<MyComp abc={2} def={2} opq={undefined} xyz={2}/>
// 渲染 abc=2 def=2 opq=1 xyz=2
