Can we employ the spread operator in generic parameters?

For instance, when working with ReactQuery's

useQuery<TQueryFnData = unknown, TError = unknown, TData = TQueryFnData, TQueryKey extends QueryKey = QueryKey>
, I aim to achieve the following:

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

const {data} = useQuery<...QueryTypeParams>(
  "anotherKey", // <- should trigger a TypeScript error
  () => {...}
)

However, the compiler gives me this warning:

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

This occurs when I attempt to use the spread operator.

Is there a way to pass generic parameters all at once?

Thanks in advance.

Answer №1

Currently, this functionality isn't available, however, there is an ongoing conversation on GitHub discussing its potential implementation.

Answer №2

Regrettably, passing generic parameters all at once does not seem to be achievable. It appears that each type must be provided individually.
