React Infinite Scroll using React Query & Intersection Observer
In this video, I implement an Infinite Scroll functionality in React.js using React Query and the Intersection Observer API — a commonly asked problem in frontend interviews and machine coding rounds.
Instead of relying on scroll events, we use a modern and efficient approach with Intersection Observer to detect when to load more data.
What you’ll learn:
✅ How Infinite Scroll works in real-world applications
✅ Using React Query for efficient data fetching & caching
✅ Using Intersection Observer API for scroll detection
✅ Handling pagination and loading states
✅ Writing clean, scalable, and interview-ready React code
This is useful for:
React JS interview preparation
Frontend machine coding rounds
Building scalable UI components
Real-world product features (feeds, lists, dashboards)
