React custom hook refetch data

const useGetFetch(url, token, user, parser) => {
  const [state, dispatch] = useReducer(fetchReducer, initialState)
  // calling refetch will force a rerender on the hook
  const [shouldRefetch, refetch] = useState({}); 

  useEffect (() => {
    if(user){
      fetch(...)
      .then((data)=> data.json())
      .then(dispatch(...)) // setting the state here
      .catch((error) => dispatch(...)) // set error state
    }
  }, [user, shouldRefetch]); // note the dep array

 // returning the refetch functions so we can call the refetch() on modal close.
 return [state.response, state.loading, state.error, refetch];
}

To trigger

refetch({});
