v0.39.0

Minor Changes

• b75fffd: Infer literal queryKey tuples in defineQuery without requiring as const. The TQueryKey type parameter now uses TypeScript 5.0's const modifier, so queryKey: ['users', userId] is inferred as readonly ['users', string] instead of being widened to string[]. This preserves the narrow key type on .options.queryKey and inside queryFn's context, matching how TanStack Query types keys when you write them inline.

  Before:

  const userQuery = defineQuery({
    queryKey: ["users", userId] as const, // `as const` required to keep the tuple
    queryFn: ({ queryKey }) => services.getUser(queryKey[1]),
  });

  After:

  const userQuery = defineQuery({
    queryKey: ["users", userId], // inferred as readonly ['users', string]
    queryFn: ({ queryKey }) => services.getUser(queryKey[1]),
  });
