npm包 - 发布vue3组件

 1. 创建VUE3项目

npm create vue

2. 在项目中创建 packages 文件夹，创建 index.js , 创建 components 文件夹，创建 PanelCard1.vue 

编辑 PanelCard1.vue

<template>
  <div style="width: 200px; height: 200px; background: grey">
    <button class="btn" @click="handleClick">ssssss</button>
  </div>
</template>
<script>
import { defineComponent } from "vue";
export default defineComponent({
  setup() {
    const handleClick = () => {
      alert("sssssssssss,我被点击了,ssssssssssss");
    };
    return {
      handleClick,
    };
  },
});
</script> 
<style scoped>
.btn {
  background: darkgoldenrod;
}
</style>

编辑 index.js

import PanelCard1 from './components/PanelCard1.vue'
const myPlugin = {
  install(app) {
    // 配置此应用
    app.component('PanelCard1', PanelCard1)
  }
}
export default myPlugin 

3. 创建 build 文件夹，创建 lib.config.js 文件

import {defineConfig} from "vite";
import {resolve} from 'path';
import vue from '@vitejs/plugin-vue';

export default defineConfig({
  build: {
    outDir: 'dist',
    lib: {
      entry: resolve(__dirname, "../packages/index.js"),
      name: 'v3tt',
      fileName: (format) => `v3tt-${format}.js`//umd es
    },
    rollupOptions: { //打包
      external: ['vue'],//不打包项
      output: {
        //UMD模式下为那些外部化的依赖提供一个全局变量
        globals: {
          vue: 'Vue'
        }
      }
    }
  },
  plugins: [
    vue({
      include: [/\.vue$/], //必须打包 包含.vue文件
    })
  ]
})

4. 修改src/main.ts

import './assets/main.css'

import { createApp } from 'vue'
import { createPinia } from 'pinia'
import App from './App.vue'

const app = createApp(App)

app.use(createPinia())

import myPlugin from "../packages/index.js";
app.use(myPlugin)


app.mount('#app')

 

修改 App.vue

<template>
  <div>
    <PanelCard1></PanelCard1>
  </div>
</template>
<script>
import {defineComponent} from 'vue';

export default defineComponent({
  setup() {
 
  }
})
</script> 

5. 修改 package.json

{
  "name": "v3tt",
  "version": "1.0.0",
  "private": true,
  "type": "module",
  "author": "lihongyuan",
  "description": "封装vue3组件库",

    "build-only": "vite build",
    "type-check": "vue-tsc --build --force",
    "build:lib": "vite build --config ./build/lib.config.js"
  },
