webpack搭建scss环境

webpack搭建scss环境

目录结构

1 scss 运行环境

node-sass scss 文件需要在node平台运行,node-sass sass 是 scss sass的运行平台

初始项目

npm init - king

2 安装依赖

• node-sass
• sass-loader 加载 Sass/SCSS 文件并将他们编译为 CS
• css-loader 解析模块要的 css @import ...
• mini-css-extract-plugin 将css语法提取单独的css 文件
• html-webpack-plugin 打包html
• webpack
• webpack-cli
• sass

3 创建webpack.config.js文件

module.exports = {
    mode: 'development',
    entry: './src/index.js',
    output: {
        path: path.resolve(__dirname, 'dist'),
        filename: '[name].js'
    },
}

4:配置loader和插件

const path = require('path');
const MineCssExtractPlugin = require('mini-css-extract-plugin')
const HtmlWebpackPlugin = require('html-webpack-plugin')

module.exports = {
    mode: 'development',
    entry: './src/index.js',
    output: {
        path: path.resolve(__dirname, 'dist'),
        filename: '[name].js'
    },
    module: {
        rules: [
            {
                test: /\.s[ac]ss$/i,
                exclude: /(node_modules|bower_components)/,
                use: [
                    MineCssExtractPlugin.loader,
                    'css-loader',
                    'sass-loader'
                ]
            },

        ]
    },
    plugins: [
        new MineCssExtractPlugin({
            filename: '[name].css'
        }),
        new HtmlWebpackPlugin({
            template: './index.html',
            filename: 'index.html',
            chunks: ['main']
        })
    ]
}

5 运行

开始打包

npx webpack

将打包后文件运行在浏览器上
