Question

下面是我的webpack配置。目前文件加载了这个main.js入口点

import './resources/assets/js/app.js';
import './resources/assets/sass/main.scss';

我可以在public / js文件中获取这两个文件，但我想将css和js放在他们自己的文件夹中。这可能吗？

var webpack = require('webpack');
var path = require('path');
let ExtractTextPlugin = require("extract-text-webpack-plugin");
var WebpackNotifierPlugin = require('webpack-notifier');

module.exports = {

    resolve: {
    alias: {
      'masonry': 'masonry-layout',
      'isotope': 'isotope-layout'
    }
  },

    entry: './main.js',
    devtool: 'source-map',
    output: {
        path: path.resolve(__dirname, './public'),
        filename: 'bundle.js'
    },

    module: {
        rules: [

         {  test: /\.js$/, 
                exclude: /node_modules/, 
                loader: "babel-loader?presets[]=es2015",

             },

            {
                test:/\.scss$/,
                use: ExtractTextPlugin.extract({
                    use: [{loader:'css-loader?sourceMap'}, {loader:'sass-loader', options: {
                    sourceMap: true
                }}],

                })
            },

            /*{
        test    : /\.(png|jpg|svg)$/,
        include : path.join(__dirname, '/dist/'),
        loader  : 'url-loader?limit=30000&name=images/[name].[ext]'
    }, */

            {
                 test: /\.vue$/,
        loader: 'vue-loader',
        options: {
          loaders: {
          }
          // other vue-loader options go here
        }
      },



        ]
    },

    plugins: [

        //new webpack.optimize.UglifyJsPlugin(),
        new ExtractTextPlugin('app.css'),
        new WebpackNotifierPlugin(),

    ]

};

Answer 1

是的，你可以这样做，这里有一个例子，它不需要你在你的js文件中导入sass文件：

const config = {
    entry: {
        main: ['./assets/js/main.js', './assets/css/main.scss'],
    },
    module: {
        rules: [
            {test: /\.(css|scss)/, use: ExtractTextPlugin.extract(['css-loader', 'sass-loader'])}
            // ...  
        ],
    },
    output: {
        path: './assets/bundles/',
        filename: "[name].min.js",
    },
    plugins: [
        new ExtractTextPlugin({
            filename: '[name].min.css',
        }),
        // ...
    ]
    // ...
}

您最终应该使用./assets/bundles/main.min.js和./assets/bundles/main.min.css。你必须明显添加js规则。

Answer 2

我们有多个入口点和输出，并按如下方式定义：

entry: {
    'js/main.min.js': './resources/assets/js/app.js', 
    'css/main.min.scss': './resources/assets/sass/main.scss'
},
output: {  
    filename: path.resolve(__dirname, './public/assets/[name]')
},

webpack读取条目的键并将其替换为输出文件名中的[name]标记。 See documentation for "output filename"

Answer 3

我有类似的需求，不确定这是否是正确的做法，但它对我有用。

output: {
        path: path.join(__dirname, './public/js'),
        filename:'bundle.js'
    },

然后是css：

plugins: [
    new ExtractTextPlugin("../css/[name].css")
],

Answer 4

ExtractTextPlugin已弃用CSS，推荐的方法是使用MiniCssExtractPlugin。

const MiniCssExtractPlugin = require('mini-css-extract-plugin');

module.exports = {
    entry: ['index.js', 'index.css'],
    module: {
        rules: [
            {
                test: /\.(scss|css)$/,
                use: [MiniCssExtractPlugin.loader, "css-loader", "sass-loader"]
            }
        ]
    },
    plugins: [
        new MiniCssExtractPlugin({
            filename: '[name]-[hash].css'
        })
    ]
};

您还需要单独安装npm i node-sass。

Answer 5

我有一个管理面板（panel.js和panel.scss）和非管理内容页面（index.js和main.scss），我想编译为2个CSS文件和2个js文件这就是我所做的：

<style>
div {
  background-image: url('custom1.png')
}
</style>

结果如下：

module.exports = {
    entry: {
        'pages': ['./src/js/index.js', './src/css/main.scss'],
        'admin': ['./src/js/admin-index.js', './src/css/admin.scss']
    },

 output: {
            filename: "./js/[name]-bundle.js",
            path: path.resolve(__dirname, "dist"), 
        },

plugins: [
 new MiniCssExtractPlugin(
            {
                filename: "./css/[name].css"
            }
        ),
   ]

}

运作良好，希望对您有帮助

mini-css-extract-plugin 可以用 webpack 5 修复

const path = require('path');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');

module.exports = {
  entry: ['./src/js/index.js', './src/scss/index.scss'],
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: '[name].js'
  },
  module: {
    rules: [
      {
        test: /\.m?js$/,
        exclude: /node_modules/,
        use: {
          loader: "babel-loader",
          options: {
            presets: ['@babel/preset-env']
          }
        }
      }, {
        test: /\.(sa|sc|c)ss$/,
        use: [
          MiniCssExtractPlugin.loader,
          'css-loader',
          'postcss-loader',
          'sass-loader',
        ],
      },
    ]
  },
  plugins: [
    new MiniCssExtractPlugin({
      filename: '[name]-[hash].css'
    }),
  ]
};

Webpack，多个入口点Sass和JS
