I want to initialize a service with argument. Each component will have its own service instance.
@Injectable()
export class LoggingService {
constructor( @Inject('group') @Optional() public group?: string) {
this.group = group;
}
}
It can be injected in to the component like this :
@Component({
selector: 'test',
templateUrl: 'test.component.html',
providers: [
LoggingService,
{ provide: 'group', useValue: 'Anythings goes here' }
]
})
export class TestComponent implements OnInit {
constructor(private logger : LoggingService) {
}
}
Above functionality is working fine for me.
I also want to inject LoggingService into TimeCalculationService. How I can provide 'group' from TimeCalculationService
@Injectable()
export class TimeCalculationService {
constructor(private logger : LoggingService) {
}
}
Is there anything like this
@Injectable({
providers : [
{ provide: 'group', useValue: 'Anythings goes here' }
]
})
