ViewResponse

ViewResponse implements the ViewModel interface in http4k and allows passing the template name as a constructor argument, in order to avoid having to implement ViewModel.template() every time.

To lookup and render the template, the framework will use the settings and components previously bootstrapped when initialising Invirt via the Invirt() filter wiring. Together with a few Invirt utility functions, this allows the handler and view model code to be kept relatively simple.

data class ListUsersResponse(
    val users: List<User>
): ViewResponse("users/list") // Points to the template `users/list.peb`

val handler =  routes(
    "/users/list" GET {
        ...
        ListUsersResponse(users).ok()
    },
    "/users/create" POST {
        ...
        CreateUserResponse(user).status(Status.ACCEPTED)
    }
)
