How can I implement caching in my React application?

You can implement caching in React using libraries like React Query or by leveraging local storage. Would you like to know more about a specific method?

What is React Query and how does it help with caching?

React Query is a powerful data-fetching library that simplifies caching, synchronization, and updating of server state in React applications. It automatically caches data and updates it in the background.

Can you show me a simple example of using React Query for caching?

Sure! First, install React Query with npm install react-query. Then, you can use the useQuery hook to fetch and cache data like this:

import { useQuery } from 'react-query';

const fetchData = async () => {
  const response = await fetch('https://api.example.com/data');
  return response.json();
};

const MyComponent = () => {
  const { data, error, isLoading } = useQuery('dataKey', fetchData);

  if (isLoading) return <div>Loading...</div>;
  if (error) return <div>Error fetching data</div>;
  return <div>{JSON.stringify(data)}</div>;
};

This will cache the data fetched from the API.
