[问题记录] webpack devServer HtmlWebpackPlugin 没有加载 js、css

webpack devServer 没有加载 js、css

HtmlWebpackPlugin runtimeChunks 注入问题。

描述

写了一个极其简单的多页面 demo
启动开发服务器，发现样式没了，打开控制台，发现 js 也没有执行。
但是 build 一切正常。
webpack 配置如下：

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

module.exports = {
    entry: {
        index: './src/index.js',
        myecharts: './src/echarts/myecharts.js',
    },
    plugins: [
        new CleanWebpackPlugin(),
        new HtmlWebpackPlugin({
            hash: true,
            filename: 'index.html',
            template: './src/index.html',
            chunks: ['index']
        }),
        new HtmlWebpackPlugin({
            hash: true,
            filename: 'html/myecharts.html',
            template: './src/echarts/myecharts.html',
            chunks: ['myecharts']
        }),
    ],
    module: {
        rules: [
            {
                test: /.css$/,
                use: [
                    'style-loader',
                    'css-loader'
                ]
            }
        ]
    },
    optimization: {
        splitChunks: {
            cacheGroups: {
                commons: {
                    name: 'commons',
                    chunks: 'initial'
                }
            }
        }
    },
    output: {
        filename: 'js/[name].js',
        path: path.resolve(__dirname, 'dist')
    },
};

解决方法

把 HtmlWebpackPlugin 升级到 4.0.0-alpha.2
