Is there a method in typescript to restrict the type of an uninstantiated class?
I am looking to specify that only classes which inherit from Repository can be accepted by the addRepository method without actually creating an instance of the class (its constructor should only be called by the service container).
Is there a way to achieve this?
import { Repository } from '../repositories/repository';
class Factory {
addRepository(repositoryClass: Repository) /* <- what should be placed here? */ { }
}
class UserRepository extends Repository {
}
let factory = new Factory();
factory.addRepository(UserRepository); // produces error
