Dealing with data in web applications poses an array of challenges. We have to handle loading and error states, manage caching, ensure consistency, update data, and more.
This is where React Query comes in — a powerful library that handles all of your data fetching needs with just a few lines of code!
But why is React Query so revolutionary for data handling? And how do we use it in our apps? Let’s explore.
Pain Points of Data Fetching
Without a good data handling solution in place, common pain points include:
- Boilerplate code — loading states, error handling, refetching all have to be implemented manually.
- Inconsistent UI — components end up out of sync if data is updated in one place but not another.
- Difficult caching — we often duplicate requests instead of reusing cached data.
- Complex logic — data fetching setup and updating gets complex in large apps.
React Query tackles all of these issues and more for us automatically.
