Modules sharing between ionic and angular 5 web app

#1

Hi,

I am trying to share the logic part between an ionic 3 and angular 5 web app. Finally I come up with structure as below, and the app work properly.

Here is my project structure:

project_folder

ionic_app
- node_modules

angular_web
- node_modules

core_modules
- node_modules

The problem comes when I build the ionic app with --prod flag, it fails at the AOT compiling. Errors show as below:

[11:05:58] ngc started …
[11:06:07] typescript error
Error encountered resolving symbol values statically. Calling function ‘ɵmakeDecorator’, function calls are

        not supported. Consider replacing the function or lambda with a reference to an exported function, resolving

Does anyone can address the issue?
