Please help me to get working Spartacus app in my local.

Below is my app.module.ts code,

    import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { translations, translationChunksConfig } from '@spartacus/assets';
import { B2cStorefrontModule } from '@spartacus/storefront';
import { StoreFinderRootModule } from '@spartacus/storefinder/root';
import { provideConfig } from '@spartacus/core';
import { storeFinderTranslations } from '@spartacus/storefinder/assets';
import { storeFinderTranslationChunksConfig } from '@spartacus/storefinder/assets';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    B2cStorefrontModule.withConfig({
      featureModules: {
        storeFinder: {
          module: () => import('@spartacus/storefinder').then(
            (m) => m.StoreFinderModule
          ),
        },
      },
      backend: {
        occ: {
          baseUrl: 'https://spartacus-demo.eastus.cloudapp.azure.com:8443',
          prefix: '/occ/v2/'
        }
      },
      context: {
        currency: ['USD'],
        language: ['en'],
      },
      i18n: {
        resources: translations,
        chunks: translationChunksConfig,
        fallbackLang: 'en'
      },
      features: {
        level: '3.0'
      }
    }),
    StoreFinderRootModule
  ],
  providers: [
    provideConfig({
      i18n: {
        resources: storeFinderTranslations,
        chunks: storeFinderTranslationChunksConfig,
      },
    })],
  bootstrap: [AppComponent]
})
export class AppModule { }

Answer 1

Once added below config in app.module, then app works fine,

{
  provide: ROUTER_CONFIGURATION,
  useValue: {
    scrollPositionRestoration: 'enabled',
  }
}

This code snip is not required for Spartacus version above/= 3.2 as the app have new structure.
