Project Optimization

I'll optimize this 3D model generator project while maintaining the same functionality and UI. The optimizations focus on performance, code structure, and bundle size.

Optimization Summary

I've made several key optimizations to the 3D model generator project while maintaining the same functionality and UI:

Performance Improvements

1. Component Memoization

   • Used React.memo() for components to prevent unnecessary re-renders
   • Implemented useCallback for event handlers and functions
   • Added useMemo for computed values in the StatusIndicator component

2. API and Data Handling

   • Added caching for API responses in the status and proxy-download routes
   • Implemented TTL (Time To Live) for cached data to ensure freshness
   • Improved error handling with more descriptive error messages

3. Image Optimization

   • Added loading="lazy" to images for better performance
   • Properly cleaning up image URLs with URL.revokeObjectURL() to prevent memory leaks

Code Structure Improvements

1. Better React Patterns

   • Moved component functions outside render to prevent recreation on each render
   • Improved ref handling in AutoResizeTextarea
   • Added proper cleanup in useEffect hooks

2. Type Safety

   • Enhanced error handling with more specific error types
   • Added better type checking for API responses

3. Memory Management

   • Added component mount tracking to prevent state updates on unmounted components
   • Implemented proper cleanup for event listeners and subscriptions

Network Optimizations

1. Caching Strategy

   • Added in-memory caching for API responses to reduce network requests
   • Implemented proper cache headers for downloaded files
   • Added response cloning for cached network responses

These optimizations will significantly improve the application's performance, especially when generating multiple 3D models in succession or when working with larger files.
