In this comprehensive tutorial, we'll explore how to master data fetching in your React Native apps using the incredibly powerful TanStack Query (formerly React Query). Say goodbye to manual loading states, error handling, and caching – TanStack Query handles it all seamlessly!

But that's not all! We'll also integrate Zustand, a lightweight and flexible state management solution, to handle your application's global and local states with ease. Learn how these two libraries can work together to create a smooth, performant, and delightful user experience.

What you'll learn in this video:

TanStack Query Fundamentals:
Setting up TanStack Query in your React Native project.
Making GET requests and caching data effortlessly.
Handling loading, error, and success states automatically.
Invalidation and background refetching.
Zustand for State Management:
Creating and using Zustand stores for global state.
Managing local component state that needs to be shared.
Integrating Zustand with TanStack Query for a unified data flow.
Best practices for structuring your state.
Building a Combined Application: We'll demonstrate how to effectively use both libraries in a practical example to fetch data, manage it, and display it in your UI.
This video is perfect for anyone who has completed our crash course or has a basic understanding of React Native and wants to level up their skills in data handling and state management.
