webpack - html-webpack-plugin 不适用于 webpack-dev-server

Question

Webpack，你将要了我的命。

html-webpack-plugin 在生产中运行良好。 'dist' 文件夹加载了我的 html 模板和插入的包。好酷。

但是，webpack-dev-server 不会那样做。它似乎正在创建自己的名为“Webpack App”的 html 页面并提供服务。 这到底是从哪里来的？我需要在开发和生产中保持一致，这样我才能看到发生了什么。我正在使用 webpack-merge 合并不同的配置。

• 网络包:4.29.6
• webpack-cli: 3.3.0
• webpack-dev-server: 3.2.1
• html-webpack-loader: 0.0.5,
• html-webpack-plugin: 3.0.7

});

Webpack 开发服务器不会将文件写入 dist 文件夹，它会从内存中提供 bundle。但是，如果您使用 contentBase 选项(默认为您当前的工作目录)，它将从磁盘提供这些文件。不过，内存中的文件优先于 contentBase 文件。
