Reusing data returned from a List query in a Single query

[DannyBiezen]

I have defined two endpoints to retrieve data using RTK-Query in React-Native:
/users and /users/{id}. I have two react-hooks for this

const { data } = useGetUsersQuery(undefined);
const { data } = useGetUserQuery(...);

These endpoints return the list of all the users and an individual user.

The initial screen opened by the user will call /users
As expected the users will be loaded into the store. If I then navigate to a user's profile screen I want to be able to reuse the data from the /users endpoint without making a new request to my API.
I can achieve this by reusing the hook for /users and filtering the data to get that specific user:

const { data } = useGetUsersQuery(undefined);

This works fine - however the user could go to this screen without having previously loaded the /users data. In this case we would retrieve all users instead of a single user which is not performant.

Is it possible to make sure a request is not made when a specific user has already been loaded into the list?

Every query is independent and has totally separate cache entries. In other words, there's no "normalization" of results to deduplicate values across separate queries. This is an intentional part of RTKQ's design:
