第一个Vue插件从封装到发布

vue init webpack-simple projectName
cd projectName
cnpm install //安装依赖

import vueAreaSelect from './components/vue-area-select' //引入组件
const areaSelect = {
 install (Vue, options) {
 Vue.component(vueAreaSelect.name, vueAreaSelect) //全局组件
 }
}

export default areaSelect //导出

//引入
import areaSelect from './index.js'

Vue.use(areaSelect)


//.vue中 使用

<vue-area-select></vue-area-select>

 // entry: './src/main.js', //npm run dev时 demo调试的入口
 entry: './src/index.js', //打包时 插件入口
 output: {
 path: path.resolve(__dirname, './dist'),
 publicPath: '/dist/',
 // filename: 'build.js'
 filename: 'vue-area-select-lei.js', //打包生成文件的名字
 library:'AreaSelect', //reqire引入的名字
 libraryTarget:'umd',
 umdNamedDefine:true
 }

 "private": false,
 "main": "dist/vue-area-select-lei.js", //import引入时默认寻找的文件
 "repository": { //仓库地址
 "type": "git",
 "url": "https://github.com/leichangchun/vue-area-select"
 },

npm install vue-area-select-lei --save //安装
//插件的方式引入使用
import areaSelect from 'vue-area-select-lei'
Vue.use(areaSelect)
