 In most cases, you shouldn't and don't need to cache single-instance components. The most common type of components that need caching are ones in big lists. Since these components are usually driven by objects in database collections, they can make use of a simple caching strategy: generate their cache keys using their unique id plus the last updated timestamp:
 
 ``` js
-server: {
-  getCacheKey: props => props.item.id + '::' + props.item.last_updated
-}
+serverCacheKey: props => props.item.id + '::' + props.item.last_updated
