Usage & Trade-offs
All fields support markdown. Use concise bullets and concrete situations.
When to use it
*
Implement Infinite Scroll when: - Displaying large lists like social feeds or image galleries. - Enhancing mobile UX with continuous content flow. - Reducing navigation friction for discovery apps. - A/B testing against pagination for engagement.
Pros
*
- Improves perceived performance and user retention. - Reduces clicks for accessing more content. - Natural scrolling behavior mimics native apps. - Efficient with virtual scrolling for large datasets. - Easy to implement with React Query or similar.
Cons
*
- Can lead to endless scrolling and content overload. - Poor SEO as all content isn't pre-loaded. - Memory leaks if not handling unmounts properly. - Accessibility issues for keyboard/screen reader users. - Harder to track user progress or jump to items.
Notes
Note: Add a "load more" button fallback for control. Use debounce on scroll events for perf. Implement skeleton loaders for smooth transitions.
