使用Webpack2(或3)时,我可以编写如下代码:

const coreStyles = new ExtractTextPlugin('./styles/core.bundle.css');
const componentStyles = new ExtractTextPlugin('./styles/components.bundle.css');

rules: [
{
   test: /\.scss$|\.css$/,
   include: path.resolve(__dirname, './styles/App.scss'),
   use: coreStyles.extract({
       use: ['css-loader', 'sass-loader']
   })
},
{
   test: /\.scss$|\.css$/,
   exclude: path.resolve(__dirname, './styles/App.scss'),
   use: componentStyles.extract({
       use: ['css-loader', 'sass-loader']
   })
}
]

结果,我输出了2个CSS文件。

我怎样才能达到同样的效果 mini-css-extract-plugin 是吗?根据文档,我只能指定一个文件名:

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

谢谢。

此示例也符合SCSS,并且不使用minicsSextracPlugin

npm install --save-dev file-loader
npm install --save-dev extract-loader

然后在webpack.config.js中

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

var path = require("path");

module.exports = {
    entry: ['./blocks.js','./block.editor.scss','./block.style.scss'],
    mode: 'production',//change to 'development' for non minified js
    output: {
        path: path.resolve(__dirname, "dist"),
        filename: 'blocks.build.js',
        publicPath: "/dist"
    },
    watch:true,
    module: {
        rules: [
            {
                test: /.js$/,
                loader: 'babel-loader',
                exclude: /node_modules/,
            },
            {
                test: /\.scss$/,
                use: [  
                    {
                        loader: 'file-loader',
                        options: {
                            name: '[name].build.css',
                            context: './',
                            outputPath: '/',
                            publicPath: '/dist'
                        }
                    },
                    {
                        loader: 'extract-loader'
                    },
                    {
                        loader: 'css-loader',
                    },
                    {
                        loader: 'sass-loader',
                        options: {
                            sourceMap: true
                        }
                    }
                ]
            },
        ],
    },
};
