Description
when generating a new application, then running the modernize tool from the Angular MCP server the following changes are made:
// app.ts
@Component({
selector: 'app-root',
imports: [RouterOutlet],
templateUrl: './app.html',
styleUrl: './app.css',
changeDetection: ChangeDetectionStrategy.OnPush, // added
})
// app.config.ts
export const appConfig: ApplicationConfig = {
providers: [
provideZonelessChangeDetection(), // added
provideBrowserGlobalErrorListeners(),
provideRouter(routes),
],
};this is either a shortcoming of the application generator (missing those two additions) or a hallucination on part of the MCP server (adding properties that don't need to be added)
Minimal Reproduction
ng new
install mcp server
prompt "please modernize my angular application"
