import { useState } from 'react';
import { useQuery as _useQuery } from 'react-apollo-hooks';

export function useLoadMore(fetchMore, data, variables) {
  const [ isLoadingMore, setIsLoadingMore ] = useState(false);

  function loadMore() {
    setIsLoadingMore(true);
    fetchMore({
      variables: {
        ...variables,
        skip: data.list.length,
      },
      updateQuery: (previousResult, { fetchMoreResult }) => {
        setIsLoadingMore(false);
        if (!fetchMoreResult) {
          return previousResult;
        }
        return {
