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)
