在设置新项目进行开发时,应用程序不支持热重载。该应用程序由多个应用程序组成,分别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
。每个应用程序都由 index.html
、style.css
和 main.js
组成,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 src/apps/second_app/main.js
中的某些内容。它不支持热重载,我必须手动重新加载才能获取更改。我已经设置了一个 webpack-dev-server。控制台有错误提示。我无法弄清楚配置文件出了什么问题。
控制台出错

将
runtimeChunk: 'single'
添加到 webpack.dev.js 对我有用。找到答案在这里
module.exports = {
...,
optimization: {
runtimeChunk: 'single'
},
...
}
也适用于我,但在主机应用程序中出现以下错误
