React Query: Road Map For Mastering React Query!

React Query is a powerful library for managing and caching asynchronous data in React applications. It's commonly used for fetching and updating data from APIs, handling caching, and managing the state of your data.

To get started, here's a roadmap you can follow to learn React Query:

Prerequisites:
Make sure you have a good understanding of React, including components, hooks, and state management using useState and useEffect.

Installation:
Start by installing React Query in your project. You can use npm or yarn for this:

npm install react-query
# or
yarn add react-query

1. Basic Concepts:

Learn about the core concepts of React Query:

• Queries: Fetching and caching data.
• Mutations: Updating data on the server.
• Infinite Queries: Paginating large data sets.
• Query Keys: Identifying queries and data.
• Query Client: The main context for queries and mutations.

2. Queries:

• useQuery: Fetch data using the useQuery hook.
• Query Function: Define a function that fetches data.
• Query Options: Customize the behavior of queries.
• Caching: React: Query handles caching automatically.
• Invalidations: Manually invalidate cache when data changes.

3. Mutations:

• useMutation: Perform server-side updates using the useMutation hook.
• Optimistic Updates: Update the UI optimistically before the server responds.
• Invalidations: Automatically update cache after a successful mutation.

4. Infinite Queries:

• useInfiniteQuery: Handle paginated data using the useInfiniteQuery hook.
• Pagination Function: Define a function that fetches paginated data.
• Scrolling: Load more data as the user scrolls.

5. Advanced Topics:

• Prefetching: Fetch data in advance to improve user experience.
• Query Retries and Error Handling: Handle failed requests gracefully.
• Background Data Sync: Keep data up-to-date in the background.
• Server-Side Rendering (SSR): Use React Query with server-side rendering.

6. React Query Devtools:

Install and use the React Query Devtools to visualize and debug your queries and cache.
