Putting it all into practice

At this point, you should be able to start handling some use cases for data fetching using the useQuery hook.

In this section, we will look at a file with three components called ComponentA, ComponentB, and ComponentC that are doing some data fetching. We will use this file to review the concepts we have learned about and see if we fully understood how useQuery works.

Let’s start with the beginning of the file:

import { useQuery, useQueryClient } from "@tanstack/react-query";
const fetchData = async ({ queryKey }) => {
  const { apiName } = queryKey[0];

    `https://danieljcafonso.builtwithdark.com/${apiName}`
  );
  if (!response.ok) throw new Error("Something failed in
    your request");
  return response.json();
};
const apiA = "react-query-api";
const apiB = "react-query-api...
