Getting Started

Install React Query in your project:

npm install @tanstack/react-query

Set up a QueryClientProvider in your app:

import { QueryClient, QueryClientProvider } from '@tanstack/react-query';

const queryClient = new QueryClient();

function App() {
  return (
    <QueryClientProvider client={queryClient}>
      <YourAppComponents />
    </QueryClientProvider>
  );
}

Basic Example: Fetching Data

Let’s fetch some data using the useQuery hook:

import { useQuery } from '@tanstack/react-query';
import axios from 'axios';

function FetchExample() {
  const { data, isLoading, error } = useQuery(
    ['users'], // Unique key for caching
    async () => {
      const response = await axios.get('https://api.example.com/users');
      return response.data;
    }
  );

  if (isLoading) return <p>Loading...</p>;
  if (error) return <p>Error: {error.message}</p>;

  return (
    <ul>
      {data.map(user => (
        <li key={user.id}>{user.name}</li>
      ))}
    </ul>
  );
}

Why Use React Query? 🤔

• No More Global State Management: Say goodbye to manually storing API data in Redux or Context.
• Automatic Optimizations: Handles stale data, refetch intervals, and on-demand queries.
• Developer Productivity: Write less boilerplate and focus on building features.
