Routing could also be shared; you could declare endpoints in one place, but the implementations for client and server would be different. At the risk of oversimplifying: on the server, routed actions are concerned with getting data from a database, serializing it, and sending it to the client. On the client, routed actions get data from the server and use it to render a template.
