I'll refactor the SemVer calculator to use SWR (stale-while-revalidate) for data fetching. This will simplify our state management and provide automatic revalidation and caching.

These changes accomplish the following:

1. We've created a custom hook usePackageVersions that uses SWR to fetch and manage package data.
2. The hook handles fetching, caching, and revalidation of package data.
3. Version matching is now done within the hook, simplifying the main component.
4. The main component now uses fewer state variables, relying on the SWR hook for most of the data management.
5. Real-time version highlighting is maintained as you type the version range.
6. Loading and error states are handled by SWR, simplifying our component logic.
7. The UI remains consistent with the previous version, maintaining accessibility and using shadcn/ui components.

This refactored version provides several benefits:

• Automatic caching and revalidation of package data
• Simplified state management in the main component
• Improved separation of concerns with data fetching logic in a custom hook
• Maintained functionality and UI from the previous version

The SemVer calculator now uses SWR for data fetching, resulting in a more efficient and maintainable codebase while preserving all the functionality from the previous version.

To address the error, I'll modify the main component file to ensure it's properly exported as the default export. Here's the revised code:

The main changes made to address the error are:

1. Ensured that the SemverCalculator component is exported as the default export using export default function SemverCalculator().
2. Double-checked that all imports are correct and the file names match the imports.
3. Verified that the custom hook usePackageVersions is properly exported and imported.

These changes should resolve the "Component cannot be found" error. The component is now correctly exported as the default export, which should allow it to be imported and used in other parts of the application.

Remember to import this component in your main application file (e.g., app/page.tsx or wherever you're using it) like this:

This should resolve the error and allow the SemVer Calculator to function correctly in your application.
