webpack 用于编译 JavaScript 模块。一旦完成安装，就可以通过 webpack 的 CLI 或 API 与其配合交互。

首先创建一个目录，进入目录中，初始化npm 然后本地安装webpack，webpack-cli ，lodash

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
