Prefer object syntax for useQuery

You can use useQuery in two different ways.

Standard

tsx
useQuery(queryKey, queryFn?, options?)
// or
useQuery(options)

tsx
useQuery(queryKey, queryFn?, options?)
// or
useQuery(options)

This rule prefers the second option, as it is more consistent with other React Query hooks, like useQueries. It will also be the only available option in a future major version.

Examples of incorrect code for this rule:

js
/* eslint "@tanstack/query/prefer-query-object-syntax": "error" */
import { useQuery } from '@tanstack/react-query';
useQuery(queryKey, queryFn, {
  onSuccess,
});
useQuery(queryKey, {
  queryFn,
  onSuccess,
});

js
/* eslint "@tanstack/query/prefer-query-object-syntax": "error" */
import { useQuery } from '@tanstack/react-query';
useQuery(queryKey, queryFn, {
  onSuccess,
});
useQuery(queryKey, {
  queryFn,
  onSuccess,
});

Examples of correct code for this rule:

js
import { useQuery } from '@tanstack/react-query';
useQuery({
  queryKey,
  queryFn,
  onSuccess,
});

js
import { useQuery } from '@tanstack/react-query';
useQuery({
  queryKey,
  queryFn,
  onSuccess,
});

If you don't care about useQuery consistency, then you will not need this rule.
