Почему опция writeToDisk заставляет мою сборку разработки зависать?

/ 27 февраля 2020

По умолчанию webpack-dev-server не записывает на диск. Мы должны передать опцию, чтобы включить это. Когда я прохожу writeToDisk: true сборка зависает. Без этой опции все работает нормально. Но я хочу записать на диск.

Вот мой файл конфигурации

webpack.dev.config. js

const path = require('path');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
const HtmlWebpackPlugin = require('html-webpack-plugin');

module.exports = {
    entry: {
        'hello-world': './src/hello-world.js',
        'kiwi': './src/kiwi.js'
    },
    output: {
        filename: '[name].bundle.js',
        path: path.resolve(__dirname, 'dist'),
        publicPath: ''
    },
    mode: 'development',
    devServer: {
        contentBase: path.join(__dirname, 'dist'),
        index: 'index.html',
        port: 9000,
        hot: true,
        writeToDisk: true      //-------------- if i remove this line, everything works fine
    },
    module: {
        rules: [
            {
                test: /\.(png|jpg)$/,
                use: [
                    'file-loader'
                ]
            },
            {
                test: /\.css$/,
                use: [
                    'style-loader', 'css-loader'
                ]
            },
            {
                test: /\.scss$/,
                use: [
                    'style-loader', 'css-loader', 'sass-loader'
                ]
            },
            {
                test: /\.js$/,
                exclude: /node_modules/,
                use: {
                    loader: 'babel-loader',
                    options: {
                        presets: [ '@babel/preset-env' ],
                        plugins: [ '@babel/plugin-proposal-class-properties' ]
                    }
                }
            },
            {
                test: /\.hbs$/,
                use: [
                    'handlebars-loader'
                ]
            }
        ]
    },
    plugins: [
        new CleanWebpackPlugin({
            cleanOnceBeforeBuildPatterns: [
                '**/*',
                path.join(process.cwd(), 'build/**/*')
            ]
        }),
        new HtmlWebpackPlugin({
            filename: 'hello-world.html',
            chunks: ['hello-world'],
            title: 'Bye World',
            template: 'src/page-template.hbs',
            description: 'some description'
        }),
        new HtmlWebpackPlugin({
            filename: 'kiwi.html',
            chunks: ['kiwi'],
            title: 'Kiwi',
            description: 'Kiwi',
            template: 'src/page-template.hbs'
        })
    ]
}
