Angular 2 DI: pass input binding to deps of factory provider

As a possible solution you can try to do it something like this:

const myServiceFactory = (self: Child) => {
  return new MyService(self.param);
};

class MyService {
  constructor(private param: string) {}
}
@Component({
  selector: 'child',
  template: `{{ param }}`,
  providers: [
    {
      provide: MyService,
      useFactory: myServiceFactory,
      deps: [Child]
    }
  ]
})
export class Child {
  @Input() param: any;

  constructor(private inj: Injector) { }

  ngOnInit() { // or ngOnChanges
    let service = this.inj.get(MyService);
  }
}
