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 🙏

自定义UI组件库

创建Vue 3 + TypeScript + Vite项目

vue create paowx-ui

目录调整

packages -- 用于存放所有的组件
src -- 用于进行测试

vite.config.js文件配置

新增vite.config.js配置

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import path from 'path'
export default defineConfig({
  plugins: [
    vue(),
  ],
  build: {
    outDir: 'lib',
    lib: {
      entry: path.resolve(__dirname, 'packages/index.ts'),
      name: 'paowx-ui',
      fileName: 'paowx-ui',
    },
    rollupOptions: {
      // 外部化处理那些你不想打包进库的依赖
      external: ['vue'],
      output: {
        // 在UMD 构建模式下为遮羞外部化的依赖提供一个全局变量
        globals: {
          vue: 'Vue'
        }
      }
    }
  }
})

统一导出packages中所有的组件

在packages中新建index.ts,用于导出所有组件


import Button from './button.vue'
// 存储组件列表
const components = [
    Button
]
// 定义 install 方法,接收 Vue 作为参数。如果使用 use 注册插件,则所有的组件都将被注册
const install = function(Vue){
    // 遍历注册全局组件
    components.forEach((item) =>{
        Vue.component(item.name, item)
    })
}
// 判断是否是直接引入文件,如果是,就不用调用 Vue.use()
if (typeof window !== 'undefined' && window.Vue) {
    install(window.Vue)
  }
  
// 导出的对象必须具有 install,才能被 Vue.use() 方法安装
export default {
    install
}

发布到npm

1、在package.json的script中新增一条打包命令
    "lib": "vue-cli-service build --target lib packages/index.js"

2、发布到npm
修改package.json文件
    "private": false,
    "main": "lib/paowx-ui.umd.cjs",
    "module": "lib/paowx-ui.js",
    "style": "lib/style.css",
    "author":{
        "name": "paowx"
    },
    "files": [
        "lib/*",
        "packages/*",
        "Readme.md",
        "package.json"
    ],

3、增加.npmignore文件
    # 忽略目录
    examples/
    packages/
    public/
        
    # 忽略指定文件
    vue.config.js
    babel.config.js
    *.map

4、npm发布
    npm login
    npm publish

    https://www.npmjs.com/package/paowx-ui

rollup

rollup打包 cjs、esm、umd 输出格式

如果需要script标签引入的方式,建议打包为umd 如果应用场景兼容ES6,可打包为esm 用 Rollup 编译为 UMD 或 CommonJS 格式,需要在 package.json 文件的 main 属性中指向当前编译的版本 编译为ESM格式,需要在package.json 文件的 module 属性中指向当前编译版本

1、CJS规范: 规范代表库为CommonJS,主要用于后端,在nodejs中,node应用是由模块组成,采用的commonjs模块规范

2、ESM规范: esm规范是es6原生支持的,很多浏览器开始支持,类似commonjs的写法和同、异步加载机制能通过设置type=module,用于html中,而且在node中也支持; export 向外暴露或导出模块 export default xxx; import 引入暴露或导出的模块 import {xx, xx} from './xxx.js'; esm为静态导入,正因如此所以可在编译期间进行Tree Shaking,减少js体积;

3、UMD规范: 一种兼容 cjs 与 amd 的模块,既可以在 node/webpack 环境中被 require 引用,也可以在浏览器中直接用 CDN 被 script.src 引入。
