It's not just react query, you can make a quick useFetch and useMutation hooks (or claude can), it's not that complex. If you don't need more advanced features (eg caching), you can easily cut down on 3rd party dependencies.

    import { useState, useEffect } from "react";

    function useFetch(url) {
      const [data, setData] = useState(null);
      const [loading, setLoading] = useState(true);
      const [error, setError] = useState(null);

      useEffect(() => {
        const controller = new AbortController();

        fetch(url, { signal: controller.signal })
          .then((res) => res.json())
          .then((json) => {
            console.log("Data:", json);
            setData(json);
          })
          .catch((err) => {
            if (err.name !== "AbortError") {
              console.error("Fetch error:", err);
              setError(err);
            }
          })
          .finally(() => setLoading(false));

        return () => controller.abort();
      }, [url]);

      return { data, loading, error };
    }







    function App() {
      const { data, loading, error } = useFetch("https://jsonplaceholder.typicode.com/todos/1");

      if (loading) return <p>Loading...</p>;
      if (error) return <p>Error</p>;
      return <pre>{JSON.stringify(data, null, 2)}</pre>;
    }
