The Modern.js micro frontend scheme is based on the Garfish package and provides some more out-of-the-box usage.
When your main application and sub-application are not all Modern.js applications, you can refer to this document.
Modern.js subapps compile to generate a standard Garfish subapp export. So you can directly access the standard micro frontend main application.
The child application is Modern.js, when the main application uses the native Garfish micro frontend, the child application debugging mode is not available.
The Main App is Modern.js, and other technology stacks used by sub-applications. Sub-App can be developed according to Garfish Sub-Application Standard.
