仅当第一个Angular实例更改时，才会在第二个Angular实例上执行热重装

Question

为了进行类似安装的生产，我想将Angular和PHP的所有开发服务器端都隐藏在nginx反向代理后面（侦听端口8002）。 在大多数情况下，这是可行的。 该API可以正确地传递其数据并按预期处理请求。 Angular开发服务器还可以按预期交付其应用程序。 我唯一遇到的问题是关于第二个Angular dev服务器实例的热重载，因为它仅在第一个实例中的更改时重载。

在端口4200上运行的主要angular应用程序可以在热重载时正常工作。 但是，第二个实例（在端口4300上运行）不会监听位置为~ ^/collector/sockjs-node/的sockjs实例，而是监听位置为~ ^/sockjs-node/的sockjs实例。 因为我的index.html中的基础设置为正确的路径：<base href="/collector/">。这使我感到惊讶。

因此，我可以得出结论，我（可能）必须更改一些角度设置，以使其能够在其他端点上通知应用程序。 我的angular.json几乎是系统自动生成的配置，除了我添加了angular的PWA软件包。

以下是我的angular.json，其中应用名称已由“ some-app”替换，因为它仍在开发中且尚未发布：

如果也可以在nginx中修复，这是我当前的设置文件，该文件包含在http的{​​{1}}设置栏中：

/etc/nginx/nginx.conf
