Strategizing 'Preloading' and 'Prefetching' with Vue Router

Preloading fetches resources needed for the current route immediately; prefetching fetches resources for future routes during browser idle time.

In a large Vue SPA, bundle size is an issue. Architecturally, you should use import() for lazy-loading. To optimize further, use webpack/vite 'magic comments' to hint to the browser. Preload critical paths (like the 'User Dashboard') so they are available immediately. Prefetch secondary paths (like 'Settings') so they are ready before the user even clicks the link.
