Question

在设置新项目进行开发时，应用程序不会热重载。该应用程序由多个应用程序组成，位于不同的文件夹中。目前，html_nodes_prototype 文件夹中有 2 个应用程序second_app 和 src/apps。每个应用程序都包含 index.html、style.css 和 main.js，当我访问链接 http://localhost:8080/second_app/second_app.html 时，应用程序会显示，但如果我更改了 src/apps/second_app/main.js 中的某些内容。它不会热重载，我必须手动重载才能获得更改。我已经设置了一个 webpack-dev-server。控制台中的错误提示。我无法弄清楚配置文件有什么问题。

控制台错误

将 runtimeChunk: 'single' 添加到 webpack.dev.js 对我有用。找到答案here

module.exports = {
    ...,
    optimization: {
        runtimeChunk: 'single'
    },
    ...
}

如何解决 ChunkLoadError: Loading hot update chunk second_app failed in webpack 5？
