How do you avoid a double DB query if both `generateMetadata` and the page call `getUser(id)`?

✓Correct answer: Wrap the function in React's cache() - deduplication within one request
2Store the user in a module-level global variable on the server
3Pass the data from generateMetadata to the page via its props

Explanation

cache() memoizes calls with the same arguments for the duration of one server render. Next.js deduplicates fetch with identical parameters itself, but ORMs and SDKs need cache(). A global variable would mix different users' data.
