You can optimize JavaScript bundle size by identifying large components and suggesting dynamic import strategies. This process analyzes component sizes and dependency graphs to implement route-level splitting and conditional loading of non-critical UI elements, improving initial page load times.

Dynamic import strategy works for component optimization by deferring the loading of heavy or non-critical UI elements until they are required. By analyzing dependency graphs, you can break down large components and fetch them on demand, which minimizes the initial JavaScript payload sent to the browser.

Yes, you can use Next.js App Router for route-level code splitting. The optimizer leverages the App Router's built-in capabilities to automatically split code at the route level, ensuring users only download the JavaScript necessary for the requested page rather than the entire application bundle.

The best way to conditionally load non-critical UI components is through dynamic imports triggered by user interaction. This strategy defers loading heavy elements like modals or complex charts until they are explicitly needed, preventing them from blocking the initial page load and degrading user experience.

You should avoid code splitting for small, lightweight components where the overhead of additional network requests outweighs the benefits. Splitting is most effective for large, complex components that heavily impact initial load times, rather than critical UI elements needed immediately upon page render.
