vue3+vite封装组件发布npm包

qq_184177677 2022-09-29 我要评论

创建项目

“vue”: “^3.2.8”
“vite”: “^2.5.2”

习惯用HB的直接用创建vue3项目即可或

npm init vite@latest

创建组件

打开项目在src/components文件夹下新增文件,我这里叫TestBtn.vue

<template>
  <button>我是测试要发布的按钮组件</button>
</template>
 
//导出组件名*
<script>
	export default{
		name:'test-btn'
	}
</script> 
<script setup>

</script>
 
<style>

</style>

拿到当前项目里测试一下

//app.vue
<template>
	<div>
		<test-btn></test-btn>
	</div>
</template>

<script setup>
import TestBtn from './components/TestBtn.vue'
</script>

<style scoped>

</style>

导出组件

src下新建index.js

//index.js
import TestBtn from "./components/TestBtn.vue"; // 引入封装好的组件

export { TestBtn } //实现按需引入*


const components = [TestBtn];
const install = function(App, options) {
	components.forEach((component) => {
		App.component(component.name,component);
	});
};
export default { install } // 批量的引入*

使用vite构建

编辑vite.config.js文件,新增build属性，vite中文文档

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import path from 'path'
// https://vitejs.dev/config/
export default defineConfig({
  plugins: [vue()],
  build: {
    lib: {
      entry: path.resolve(__dirname, 'src/index.js'),
      name: 'TestBtn',
      fileName: (format) => `test-btn.${format}.js`
    },
    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'
        }
      }
    }
  }
})

修改package.json文件

{
	"name": "test-btn-ui",
	"version": "0.0.1",
	"scripts": {
		"dev": "vite",
		"build": "vite build",
		"serve": "vite preview"
	},
	"files": ["dist"],
	"main": "./dist/test-btn.umd.js",
	"module": "./dist/test-btn.es.js",
	"exports": {
		".": {
			"import": "./dist/test-btn.es.js",
			"require": "./dist/test-btn.umd.js"
		}
	},
	"dependencies": {
		"vue": "^3.2.8"
	},
	"devDependencies": {
		"@vitejs/plugin-vue": "^1.6.0",
		"@vue/compiler-sfc": "^3.2.6",
		"vite": "^2.5.2"
	}
}

打包

生成dist文件

npm run build

注册->登录npm

按提示注册就可以 npm官网

发布前准备

在dist文件生成package.json文件，自定义组件名(唯一，重名报错重新起一个就行),版本号每次上传要高于前一次版本号

//dist文件下
npm init -y

//package.json
{
  "name": "test-btn-ui",
  "version": "1.0.4",
  "description": "",
  "main": "test-btn.es.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
}

发布到npm

npm publish

其他项目引用

npm i test-btn-ui

//main.js
import { createApp } from 'vue'
import App from './App.vue'
import TestBtnUI from 'test-btn-ui'
import 'test-btn-ui/style.css'

createApp(App).use(TestBtnUI).mount('#app')

//页面.vue
<template>
	<test-btn></test-btn>
</template>

<script setup>

</script>

<style scoped>

</style>
