window启动webpack打包的三种方法

1.在cmd终端执行 npx webpack命令

2.在package.json文件同级建立webpack.config.js文件，内容如下：

const path = require('path');

module.exports = {

  entry: './src/index.js',             // 入口

  output: {                            // 出口

    filename: 'bundle.js',             // 文件名

    path: path.resolve(__dirname, 'dist')       // 生成路径

  }

};

执行命令 npx webpack --config webpack.config.js

3.修改package.json脚本

{

    "name": "webpack-demo",

    "version": "1.0.0",

    "description": "",

    "main": "index.js",

    "scripts": {

      "test": "echo \"Error: no test specified\" && exit 1",

+     "build": "webpack"                         // 修改命令执行方法

    },

    "keywords": [],

    "author": "",

    "license": "ISC",

    "devDependencies": {

      "webpack": "^4.0.1",

      "webpack-cli": "^2.0.9",

      "lodash": "^4.17.5"

    }

  }

执行命令npm run build

结论：生成类似下面的目录，打开index.html 有Hello webpack显示

webpack-demo

|- package.json

|- webpack.config.js

|- /dist

  |- bundle.js

  |- index.html

|- /src

  |- index.js

|- /node_modules
