Boost your application's performance with React Query!

✨ What if you could eliminate the complexity of asynchronous data management in your React and React Native application? React Query can help you by simplifying and optimizing server state ✨

How the also known as TanStack Query works:

  • 📦Cache(QueryCache):

    • React Query stores data in the cache, avoiding repeated server requests.
  • Data Status:

    • 👶Fresh → Like the data's validity, after a certain time the data becomes stale.
    • 👴Stale → Obsolete data, meaning a new server request is needed to update it.
  • ♻️ SWR (Stale-While-Revalidate):

    • SWR ensures your data is always fresh.
    • It displays cached data immediately (even if "stale" or obsolete) while fetching the latest version in the background. Thus, the user sees the content instantly, and the update is smooth.
  • 𝗦𝗶𝗺𝗽𝗹𝗶𝗳𝗶𝗲𝗱 𝗗𝗮𝘁𝗮 𝗠𝗮𝗻𝗮𝗴𝗲𝗺𝗲𝗻𝘁

    • React Query eliminates the need to write complex code to fetch, update, and manage server state. It takes care of:
      • ⚙️**Automatic cache: **No need to implement manual logic.
      • 🔁Revalidation: Automatic data update.
      • ⚠️Error handling: Handles request errors.
      • 🚀Optimistic updates: Improves perceived performance by updating the interface before server confirmation.

Great post on React Query! It’s such a powerful tool for handling server-state in React applications. If anyone is looking for a beginner-friendly guide to setting up React Query in a Next.js app, I wrote an article that covers the setup, usage, and common patterns with some practical examples. Feel free to check it out here: Guide to React Query.
