vue封装组件发布到npm,支持unplugin-vue-components按需引入_npm中手动引入插件

目的：vue封装组件发布到npm,支持unplugin-vue-components按需引入

• vue组件 gitee plugin-vue-components
• 工具类 gitee plugin-validate
• taro组件 gitee plugin-taro-components

本篇文章只介绍plugin-vue-components组件，工具类和taro组件可直接看代码
先上效果：https://www.npmjs.com/package/plugin-vue-components

plugin-vue-componets

安装

npm i -S plugin-vue-components
1

引入

方式一 按需手动引入

main.ts引入样式

import "plugin-vue-components/dist/style.css"//引入样式
1

vue组件中使用

<template>
            <IoUpload>IoUpload</IoUpload>
            <IoList></IoList>
</template>
 import { Upload as IoUpload, List as IoList } from 'plugin-vue-components'

方式二 基于unplugin-vue-components按需引入

   npm install --save unplugin-vue-components
1

vite.config.ts文件中添加配置

import Components from 'unplugin-vue-components/vite'
plugins:[
    Components({
      resolvers: [
       (componentName) => {
          if (componentName.startsWith('Io'))
            return { name: componentName, from: 'plugin-vue-components' }
        },
      ],
]

方式三（推荐使用）基于unplugin-vue-components按需自动引入

   npm install -D unplugin-vue-components

vite.config.ts文件中添加配置

import Components from 'unplugin-vue-components/vite'
import IoUIResolver from 'plugin-vue-components/resolver'
plugins:[
    Components({
      resolvers: [
       IoUIResolver(),
      ],
]

废弃,在main.ts全局注册

import IoComponents from 'plugin-vue-components'
import "plugin-vue-components/dist/style.css"//引入样式
    
const app = createApp(App)
app.use(IoComponents)
app.mount('#app')

vue组件封装

项目结构

创建项目

npm create vite@latest

封装组件

src/packages/components/ 目录下封装组件 upload/upload.vue

<template>
    <div class="upload">上传图片
        <slot></slot>
    </div>
</template>
<style lang="css">
.upload {
    color: red;
    display: flex;
}
</style>

upload/index.ts 组件注册

import { App } from 'vue'
import Upload from './upload.vue'


Upload.install = (app: App) => {
    app.component(Upload.name, Upload)
}
export {
    Upload
}
export default Upload

组件注册

src/package/componets 目录下新建 index.ts用于组件注册

import Upload from './components/upload'
import List from './components/list'
import type { App } from 'vue'

const components = [
    Upload,
    List,
]
//注册
const install = (app: App) => {
    components.forEach((component) => {
        app.component(component.name, component)
    })
}
export {
    Upload,
    List
}
export default {
    install
}

配置组件名，入口，输出位置

根目录下新建 vite.config.build.ts

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import { resolve } from 'path'
import dts from 'vite-plugin-dts'
// 打包后的目录
// https://vitejs.dev/config/
export default defineConfig({
  resolve: {                                       // +++
    alias: {
      '@': resolve(__dirname, './src')         // +++
    }                                            // +++
  },
  plugins: [
    vue(),
    dts(),//使用的typescript，需要生成*.d.ts声明文件
  ],
  //配置打包入口 https://cn.vitejs.dev/guide/build.html#library-mode
  build: {
    lib: {
      entry: resolve(__dirname, 'src/packages/index.ts'),//入口
      name: 'plugin-vue-components',//组件名
      fileName: (format) => `plugin-vue-components.${format}.ts`
    },
    rollupOptions: {
      // 确保外部化处理那些你不想打包进库的依赖
      external: ['vue'],
      output: {
        // 在 UMD 构建模式下为这些外部化的依赖提供一个全局变量
        globals: {
          vue: 'Vue',
        },
        // dir: resolve(__dirname, 'dist') //打包输出目录
      },
    },
  },
})

配置兼容unplugin-vue-componets按需自动引入

• src/resolver.ts 处理组件引入

import type { ComponentResolveResult, ComponentResolver } from 'unplugin-vue-components/types';

function getIoResolved(name: string): ComponentResolveResult {

    const packageName = 'plugin-vue-components';

    const style = `${packageName}/dist/style.css`;

    return {
        name,
        from: packageName,
        sideEffects: style
    };
}

const IoUIResolver = (): ComponentResolver => {
    return {
        type: 'component',
        resolve: (name) => {
            if (name.startsWith('Io')) {
                return getIoResolved(name.slice(2));
            }
        }
    };
}
