# @Deprecated Please use the [official CDI addon](https://vaadin.com/directory/component/vaadin-cdi). It's API is almost the same, mainly just the package name differs. In a nutshell your route target, and layout components become CDI contextual instances. You can use any CDI feature, for example @Inject. Additional contexts: - @VaadinServiceSession - a scope for services with VaadinsServletService lifecylce like Instantiator, or I18NProvider. - @VaadinSessionScoped - a scope of a VaadinSession - @UIScoped - a scope of a UI. A pseudo scope, use it for components. - @NormalUIscoped - a scope of a UI. It is a normal scope, usable for other beans. - @RouteScoped - together with @RouteScopeOwner it can be used to bind beans to router components (@Route/ParentLayout/HasErrorParameter) - @NormalRouteScoped - distinction same as at UI scopes Non-component events fired as CDI event: - ServiceInitEvent - PollEvent - BeforeEnterEvent - BeforeLeaveEvent - AfterNavigationEvent - UIInitEvent - SessionInitEvent - SessionDestroyEvent - ServiceDestroyEvent See project readme for details.
