User Typed Selector

ts

import {RootType} from "../rootreducer";
import {useSelector} from "react-redux";

export function useTypedSelector<T>(
    selector: (state: RootType) => T,
    equalityFn?: (left: T, right: T) => boolean): T {
    return useSelector<RootType, T>(selector, equalityFn);
}

Your rootType location and name will differ
