   Thanks for the report, and sorry for the delay.

   This should be fixed in 8.8.15. In the Ionic versions available when this was filed, @ionic/angular-server crashed on every server render with attachShadow is not a function, because Angular's server DOM doesn't implement Shadow DOM, so Ionic components were sent to the browser unrendered. #30967 fixed this by having the server module detect the missing API and fall back to scoped rendering. It shipped in v8.8.15.

   One setup detail: as noted in #28625, Ionic does not support Angular's client hydration (provideClientHydration()), which ng new --ssr adds by default. Leaving it on throws NG0500 in development builds and hasAttribute is not a function in production builds. Either remove provideClientHydration(), or skip hydration for the Ionic tree:

   // app.config.server.ts
   import { mergeApplicationConfig, ApplicationConfig, importProvidersFrom } from '@angular/core';
   import { provideServerRendering } from '@angular/platform-server';
   import { IonicServerModule } from '@ionic/angular-server';
   import { appConfig } from './app.config';
   
   const serverConfig: ApplicationConfig = {
     providers: [provideServerRendering(), importProvidersFrom(IonicServerModule)],
   };
   
   export const config = mergeApplicationConfig(appConfig, serverConfig);

   <ion-app ngSkipHydration>
     <!-- your app -->
   </ion-app>

   Could someone who was blocked on this confirm that it works in your app on the latest version?
