Workaround to have withViewTransitions() running on your angular/ssr server

app.config.ts

export const baseAppConfig: ApplicationConfig = {
  providers: [
    provideRouter(routes, withComponentInputBinding())
  ],
};

export const appConfig: ApplicationConfig = mergeApplicationConfig(baseAppConfig, {
  providers: [provideRouter(routes, withComponentInputBinding(), withViewTransitions())]
});

app.server.config.ts

const serverConfig: ApplicationConfig = {
  providers: [provideServerRendering()]
};

export const config = mergeApplicationConfig(baseAppConfig, serverConfig);
