Standalone Services

Introduction

Services in standalone apps work the same way, using @Injectable with providedIn or providers arrays.

Example

@Injectable({ providedIn: 'root' })
export class UserService {
  // Tree-shakeable singleton
}

// Component-level providers
@Component({
  providers: [FeatureService],
  standalone: true
})
export class FeatureComponent { }

Summary

Standalone doesn’t change how services work — just how they’re provided.”
