目录结构：

index.html

<!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>

    <script src="bundle.js"></script>

</body>

</html>

webpack.config.js

const path = require('path');

module.exports = {

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

    output:{

        filename: 'bundle.js',

        path: path.resolve(__dirname, 'dist')

    }

}

package,json

{

  "name": "webpack-demo",

  "version": "1.0.0",

  "description": "",
