1，打包css资源

此时需要引入style-loader与css-loader。

css-loader的作用是将css以模块的形式插入到js中。

style-loader的作用是创建一个style标签，并将js中的css插入到style标签里，最后将style标签插入到html中的head里。

npm i style-loader css-loader -D

2，打包less资源

此时需要引入less与less-loader。

less-loader的作用是将less资源编译成css资源。

npm i less-loader less -D

3，打包scss资源。

此时需要引入node-scss与sass-loader。

sass-loader的作用是将scss资源编译成css资源。

npm i node-sass sass-loader -D

webpack.config.js配置如下：

const { resolve } = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
module.exports = {
    entry: './src/main.js',
    output: {
        filename: 'bundle.js',
        path: resolve(__dirname, 'dist')
    },
    module: {
        rules: [
            {
                test: /\.css$/,
                use: ['style-loader', 'css-loader']
            },
            {
                test: /\.less$/,
                use: ['style-loader', 'css-loader', 'less-loader']
            },
            {
                test: /\.scss$/,
                use: ['style-loader', 'css-loader', 'sass-loader']
            }
        ]
    },
    plugins: [
        new HtmlWebpackPlugin({
            template: './src/assets/index.html',
            hash: true,
            filename: 'index.html',
            favicon: './src/assets/favicon.ico'
        })
    ],
    mode: 'development'
}

package.json的配置如下：

{
  "name": "wpk5-demo",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "build": "npx webpack"
