verify-lazy-loading

To verify React.lazy and Suspense implementation, run a check that confirms components use dynamic imports and are wrapped in Suspense for fallback UI. This validation ensures efficient component loading and prevents large initial bundle sizes in your React application.

You need to use ErrorBoundary with lazy loaded components to handle dynamic import failures gracefully. Wrapping React.lazy components in an ErrorBoundary prevents application crashes when chunk loading fails, maintaining UI responsiveness during component loading errors.

Yes, this component loading check validates lazy loading patterns across various UI modules including tabs, modals, and managers. It verifies that large components in these modules are dynamically imported and properly wrapped with Suspense and ErrorBoundary.

The best way to optimize initial load times is implementing React.lazy with Suspense to dynamically import large components. Verifying correct import counts and Suspense wrapping ensures components load efficiently only when needed, reducing initial bundle size.

Performance bottlenecks after adding new tabs often occur when components are not lazy loaded. Without React.lazy and Suspense wrapping, all tab content loads synchronously, increasing initial bundle size and degrading application responsiveness.
