2 webpack.config.js

//
var path=require("path");

//var extractTextPlugin=require('extract-text-webpack-plugin');
var extractTextPlugin=require('mini-css-extract-plugin');
const VueLoaderPlugin=require('vue-loader/lib/plugin');

var config = {
    mode:'development',
    entry:{
        //配置的单入口，webpack会从main.js文件开始工作
        main:'./main'
    },
    
    output:{
        
        //打包后文件的输出目录
        path:path.join(__dirname,'./dist'),
        //指定资源文件引用的目录
        publicPath:'/dist/',
        //用于指定输出文件的名称
        filename:'main.js'
        
    },

    module:{

        //再module对象的rules属性可以指定一系列的loeders，每一个loader都必须包含test和use两个选项
        //此配置的意思：
        //当webpack编译过程中遇到require和import语句导入一个后缀名为.css的文件时
        //，先将他通过css-loader转换，再通过style-loader转换，然后继续打包
        rules:[

            /*{
                test:/.css$/,
                use:[
                    'style-loader',
                    'css-loader'
                ]
            }*/
            {
                test:/.vue$/,
                loader:'vue-loader',
            },

            {
                test:/.css$/,
                use:[
                        extractTextPlugin.loader,
                        'css-loader',
                    ]
            },

            {
                test:/.js$/,
                loader:'babel-loader',
                exclude:/node_modules/
            },
        ]
    },

    plugins:[
        new VueLoaderPlugin(),
        //重命名提取后的css文件
        new extractTextPlugin({

            filename: "[name].css",
            chunkFilename: "[id].css"
        }),
        
    ]

};

module.exports = config

3 最终运行npm run dev能够处理.vue文件

大家可以结合上篇笔记参考dev环境的配置
