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 🙏

@dbfu/react-directive

在react项目中使用vue指令,支持自定义指令。

安装依赖

npm i @dbfu/react-directive

使用说明

如果使用typescript,修改tsconfig.json文件

{
  "compilerOptions": {
    "jsx": "react-jsx",
    "jsxImportSource": "@dbfu/react-directive",
  }
}

如果使用webpack打包,修改babel.config.json或修改.babelrc

// .babelrc / babel.config.json
{
  "presets": [
    [
      "@babel/preset-react",
      {
        "runtime": "automatic",
        "importSource": "@dbfu/react-directive"
      }
    ]
  ]
}

如果使用vite

export default defineConfig({
  plugins: [react({
    jsxImportSource: '@dbfu/react-directive'
  })],
})

如果使用umi,先安装@babel/preset-react依赖,然后修改.umirc配置文件

 import { defineConfig } from "umi";

export default defineConfig({
  extraBabelPresets: [
    [
      "@babel/preset-react",
      {
        "runtime": "automatic",
        "importSource": "@dbfu/react-directive"
      }
    ]
  ],
});

如果使用react-create-app,先安装@babel/preset-react,然后修改package.json文件,添加babel属性。

{
"babel": {
    "presets": [
      "react-app",
      [
        "@babel/preset-react",
        {
          "runtime": "automatic",
          "importSource": "@dbfu/react-directive"
        }
      ]
    ]
  },
}

然后就可以在项目中,使用框架内置的指令

import useModel from '@dbfu/react-directive/useModel'
function App() {

  const model = useModel({ name: "jack" });

  return (
    <div v-if={false} v-show={false} v-model={[model, "name"]}>
  )
}

内置指令使用文档

v-if

和vue中的v-if一样,这个不仅可以对原生dom使用,还能对组件进行使用。

v-show

和vue中的v-show一样,这个只能对原生dom使用,因为会修改dom元素的style中display属性,如果组件支持style.display属性的话,也可以使用v-show。

v-model

这个指令效果和vue中的v-model差不多,但是用法有点区别,创建的对象必须用useModel这个hooks包装一下,还有v-model指令需要传数组,第一个值是对象,第二个参数是对象里面的key,支持多层级key。看下面的例子:

import useModel from '@dbfu/react-directive/useModel'

function App() {
 
 const model = useModel({ user: { name: 'tom' } });

 return (
  <div>
    <input v-model={[model, 'user.name']} />
    <div>{model?.user?.name}</div>
  </div>
 )
}

v-focus

表单元素自动获得焦点,和原生autoFocus属性不同的是,这个可以在一开始display:none的情况下,后面再显示时也能自动获取焦点,这个autoFocus就实现不了。只要组件实现了focus方法,也可以对组件进行使用。

v-copy

点击当前元素时,会把当前指令的值复制到剪切板上,只要支持onClick事件,无论组件或原生dom元素,都可以使用这个指令

v-text

和vue实现效果一样,只支持原生dom元素。

v-html

和vue实现效果一样,只支持原生dom元素。

自定义指令

在项目入口,从@dbfu/react-directive/directive引入directive,然后就可以自定义指令了。语法如下:

import { directive } from "@dbfu/react-directive/directive"

// name 指令名称
directive("name", {
  // 组件渲染之前,在createElement的时候,在这个生命周期可以处理组件props,然后组件渲染的时候,可以拿到处理后的props。注意这个方法只要组件一重新render,就会触发一次。如果返回false这个组件就不渲染了。
  // value:当前指令的值
  // props:当前组件的props
  create: (value, props) => {
     // example v-show的实现
     if(value === false) {
       if(props?.style) {
         props.style.display = 'none';
       } else {
         props.style = { display: 'none' };
       }
     } 
  },
  // dom元素和组件渲染的时候触发,正常情况只会触发一次。如果组件多次销毁和渲染,每次渲染都会触发这个方法。
  // 这个方法里面不能处理props,但是可以拿到组件引用活dom元素引用,可以去调用组件或dom元素的方法
  // ref:如果是组件则是组件引用,如果是dom元素就是dom的引用。
  // value:当前指令的值
  // props:当前组件的props
  mounted: (ref, value, props) => {
     // example v-text的实现
     if(isDOM(ref)) {
       ref.innerText = value;
     }

      // example v-html的实现
     if(isDOM(ref)) {
       ref.innerHTML = value;
     } 
  },
  // 这个方法是组件style.display由none转换为block时触发
  // 参数和mounted一样
  show: (ref, value, props) => {
     // example v-focus的实现
     ref?.focus?.();
  },
  // 和show相反
  hidden: (ref, value, props) => {
    // 暂无使用场景
  }
});
