Introduction
This project demonstrates an infinite scrolling implementation using the Intersection Observer API, React, and the useRef
hook. The primary focus is on preventing layout shifts and improving Cumulative Layout Shift (CLS) by ensuring that new elements are added without impacting the rest of the page.
Features
- Optimized Layout: The parent
div
is assigned a specific height, ensuring that the addition of new elements does not cause layout shifts, thereby enhancing CLS performance. - Infinite Scrolling: As you scroll, new elements are continuously added to the DOM, creating an infinite scrolling effect.
NOTE:-
- If you wanted to learn more about performance improvement I have an article on the same (https://dev.to/ashutoshsarangi/performance-improvement-for-web-applications-1plk)
Installation and Usage
To use this project, follow these steps:
-
Clone the repository:
git clone https://github.com/Ashutoshsarangi/react-infinity-loading
-
Install dependencies:
npm install
-
Run the development server
npm run dev
Limitations
While this approach successfully creates an infinite scroll, there is a limitation: It keeps adding elements to the DOM indefinitely. After around 1,000 elements, you may notice browser performance issues, such as lagging, due to the increasing number of DOM nodes. This is not ideal for a true infinite scroll experience.
Future Work
I am actively working on a more efficient solution that mitigates this issue by optimizing the handling of elements in the DOM. Once completed, I will update the repository with the new approach.
Stay tuned!
