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
