 Try to keep the `props` function stateless, as it's only evaluated on route changes. Use a wrapper component if you need state to define the props, that way vue can react to state changes.
 
+## Name mode
+
+You can pass props to component using their component name.
+
+``` js
+const router = new VueRouter({
+  routes: [
+    {
+      path: '/user-profile',
+      component: {location: Location, userInfo: UserInfo},
+      props: { userInfo: route => ({ isNewUser: false }) }
+    }
+  ]
+})
+```
+
+The URL `/user-profile` would pass `{ isNewUser: false }` to `userInfo` Component.
