Lazy Load Suggester

Not everything needs to load on first paint. This tool analyzes your components and tells you which ones should be lazy loaded for better performance.

One command. Zero config. Just works.

Quick Start

npx ai-lazy-load ./src/

What It Does

• Analyzes your component usage patterns
• Identifies heavy components that load upfront
• Suggests lazy loading candidates
• Provides code examples for implementation

Usage Examples

# Analyze all components
npx ai-lazy-load ./src/

# Focus on specific directory
npx ai-lazy-load ./src/components/

# Include pages
npx ai-lazy-load ./src/pages/

Best Practices

• Lazy load routes - users don't need all pages at once
• Heavy components - modals, charts, editors
• Below the fold - content users scroll to
• Keep critical path small - load what's visible first

When to Use This

• Initial bundle is too large
• Time to interactive is slow
• Adding code splitting to existing app
• Optimizing specific user flows

How It Works

Scans your components to understand import relationships and component sizes. The AI identifies components that aren't needed immediately and would benefit from lazy loading.
