Advanced Data Synchronization Technique

Implement query prefetching on a Next.js page link hover, demonstrating how to use React Query's prefetchQuery function to preload data for a faster user experience.

import { prefetchQuery } from 'react-query';
import { fetchPokemon } from '../api/pokemon';

First, import necessary functions. prefetchQuery from React Query is used for prefetching, and fetchPokemon is a hypothetical API call function.

const PokemonLink = ({ id, name }) => {
  return (
    <div onMouseEnter={() => prefetchPokemonData(id)}>
      {name}
    </div>
  );
};

This React component represents a link for a Pokemon. It uses onMouseEnter to trigger prefetching.

const prefetchPokemonData = async (id) => {
  await prefetchQuery(['pokemon', id], () => fetchPokemon(id));
};

This function prefetches data for a Pokemon by its ID. It uses prefectQuery with a unique key ['pokemon', id] and the fetching function.
