Type Alias LoadingAppearance

What to render when RouteOptions.lazyComponent or RouteOptions.loader are being loaded.

"loading"

A RouteOptions.loadingComponent is always rendered if a route is matched and component or loader are being loaded.

"auto"

If another route is currently rendered then it would be preserved until component and loader of a newly matched route are being loaded. Otherwise, a RouteOptions.loadingComponent is rendered.
