第一步：

npm init -y

 第二步：

npm install --save-dev vue

  第三步：

npm i --save-dev vue-loader vue-template-compiler

 第四步：

npm install webpack webpack-cli --save-dev

 添加配置文件：webpack.config.js

const path = require('path');
const VueLoaderPlugin = require('vue-loader/lib/plugin');

module.exports = {
    entry: './src/main.js',
    output:{
        path: path.resolve(__dirname,'dist'),
        filename :'bundle.js'
    },
    plugins:[
        new VueLoaderPlugin()
    ],  
    module:{
        rules:[
          {  test:  /\.vue$/,  use:'vue-loader'}
        ]
    },
    resolve:{
        alias:{
            "vue$":"vue/dist/vue.js"
        }
    }
 
}

package.json文件如下：

{
  "name": "webpack_vue",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "build": "webpack"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "vue": "^2.6.11",
    "vue-loader": "^15.8.3",
    "vue-template-compiler": "^2.6.11",
    "webpack": "^4.41.4",
    "webpack-cli": "^3.3.10"
  }
}

编写一个index.html文件如下：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
</head>
<body>
    <div id="app">
       <p>{{msg}}</p>
       <login></login>
    </div>
    <script src="../dist/bundle.js"></script>
</body>
</html>

编写一个main.js

import Vue from 'vue'
import login from './login.vue'

var vm = new Vue({
    el: '#app',
    data: {
      msg: '123'
    },
    components:{
      login
    }
  })

再写一个vue的组件 login.vue

<template>
    <h1>helloword</h1>
</template>

效果如下：

Vue之webpack之vue_Vue
