This repository contains the code examples for the articleVirtualizing React, which explores different approaches to implementing virtualization in React.

This demo showcases:

• Custom virtualization implementation from scratch
• TanStack Virtual integration
• Integration with shadcn/ui Select component
• Performance comparisons between different approaches

The article covers:

1. Understanding Virtualization
2. Pure Implementation from scratch
3. TanStack Virtual Implementation
4. Comparing both approaches

Run the development server:

pnpm dev

Openhttp://localhost:3000 with your browser to see the demo in action.

The repository includes two main implementations:

• Custom virtualization logic built from scratch
• Demonstrates core concepts like:
  • Virtual window management
  • Buffer zones
  • Height calculations
  • Position management

• Production-ready solution using TanStack Virtual
• Showcases advanced features and optimizations

Both implementations are integrated with shadcn/ui's Select component to demonstrate practical usage in a real-world scenario.

• Next.js
• TanStack Virtual
• shadcn/ui
