Ionic Framework Version

v7.x

Current Behavior

While refactoring an Ionic application for version 7.8.1, using standalone Angular components, an issue surfaced regarding the functionality of Ioinic Components in production builds.

It was observed that these components fail to function as intended during production builds. While a temporary workaround involves setting the "buildOptimization" property to false within the angular.json file, this solution is deemed unsatisfactory.

Example modification in angular.json:

{
   "projects": {
     "app": {
       "architect": {
         "build": {
           "configurations": {
             "production": {
               "buildOptimization": false,
               ...
             }
             ...
           }
           ...
         }
         ...
       }
       ...
     }
     ...
   }
   ...
}

Another solution we have found is to create a service to define all the ionic elements, but it does not seem like a suitable solution to us either.

Expected Behavior

The Ionic components ought to render accurately when integrated with standalone Angular components during production builds.

Steps to Reproduce

Complie app with:

$ ionic serve --configuration=production
