Is it possible to use spread operator in generics parameters?-CodePudding

For example with ReactQuery's useQuery<TQueryFnData = unknown, TError = unknown, TData = TQueryFnData, TQueryKey extends QueryKey = QueryKey>, I want do like;

type QueryTypeParams = [Record<string, number>, unknown, unknown, "aKey" as const]

const {data} = useQuery<...QueryTypeParams>(
  "anotherKey", // <- expects typescript error
  () => {...}
)

But the compiler saids

Variable 'QueryTypeParams' implicitly has an 'any' type.

at where I use spread operator.

Is there any way to pass generics parameters at once?

Thanks in advance.

Unfortunately, I do not think it is possible to pass generics parameters at once. You have to provide every type separately.

This is not possible at the moment but there is a discussion about this feature on GitHub.
