EmptyComponent

A component for root napkins that have no parent dependencies.

class EmptyComponent

Overview

EmptyComponent is the canonical “no upstream dependency” terminator. Use it as the parent dependency of an application’s root component when the root has nothing to inherit:

final class AppComponent: Component<EmptyDependency>, RootDependency {
    init() {
        super.init(dependency: EmptyComponent())
    }

    var userService: UserService {
        shared { UserService() }
    }
}
