Performance Optimizations
We implemented several key optimizations:
ProductList.tsx
// Optimized product list with lazy loading
import { FlashList } from '@shopify/flash-list';
const ProductList: React.FC = () => {
const { data, fetchNext } = useInfiniteQuery(
['products'],
fetchProducts,
{
getNextPageParam: (lastPage) => lastPage.nextCursor,
}
);
return (
<FlashList
data={data?.pages.flatMap(page => page.products)}
renderItem={({ item }) => <ProductCard product={item} />}
onEndReached={fetchNext}
estimatedItemSize={120}
/>
);
};Results
The app achieved remarkable success:
