When I am trying to run npm run ionic:build --prod, it is giving me below errors:
Error: Cannot determine the module for class OverlayPortal in F:/D/IONIC/quicktask/quicktask-web-froala/node_modules/ionic-angular/umd/components/app/overlay-portal.d.ts! Add OverlayPortal to the NgModule to fix it. Cannot determine the module for class IonicApp in F:/D/IONIC/quicktask/quicktask-web-froala/node_modules/ionic-angular/umd/components/app/app-root.d.ts! Add IonicApp to the NgModule to fix it. Cannot determine the module for class ClickBlock in F:/D/IONIC/quicktask/quicktask-web-froala/node_modules/ionic-angular/umd/components/app/click-block.d.ts! Add ClickBlock to the NgModule to fix it. Cannot determine the module for class Slides in F:/D/IONIC/quicktask/quicktask-web-froala/node_modules/ionic-angular/umd/components/slides/slides.d.ts! Add Slides to the NgModule to fix it.
What do I do to build using --prod. I have done npm install again, updated app/scripts, don't know what else is needed.
Find below my app.module.ts

The issue with AOT build is that, you have many plugins which are outdated and do not support AOT compilation.
In order to optimize, you can check for GZIP. This should reduce your load time significantly. GZIP needs to be done from server side and has nothing to do with your Frontend code.
