-### Excluding baseQuery for all endpoints

-<!-- TODO: move this to a 'usage with typescript' page instead-->
-
-For typescript users, the error type that `queryFn` must return is dictated by the provided `baseQuery` function. For users who wish to _only_ use `queryFn` for each endpoint and not include a `baseQuery` at all, RTK Query provides a `fakeBaseQuery` function that can be used to easily specify the error type each `queryFn` should return.
