Question 1

How do I set up lazy loading for routes in Vue Router?

Accepted Answer

Use dynamic imports in your route configuration, such as defining a component with `() => import('./views/MyComponent.vue')`. This splits code by route, loading components only when needed to optimize performance.

Question 2

Vue Router 3 or Vue Router 4: which should I use for a new project?

Accepted Answer

For new projects, choose Vue Router 4 with Vue 3, as Vue Router 3 is end-of-life and no longer maintained. Vue Router 4 offers better TypeScript integration and features aligned with Vue 3's composition API.

Question 3

Can Vue Router handle nested routes with dynamic parameters?

Accepted Answer

Yes, it supports nested routes with dynamic segments. Define child routes in the parent configuration and access URL parameters via `$route.params` in components, enabling complex hierarchical UIs as per the nested route feature.

Question 5

Is Vue Router 3 still safe for existing Vue 2 projects?

Accepted Answer

It's stable for existing Vue 2 projects but carries risks due to its end-of-life status. Consider migrating to Vue Router 4 if upgrading to Vue 3, or ensure no critical unpatched bugs affect your application.

What are navigation guards and how do I use them for authentication?
