What are the differences between Vue's keep-alive and router?

Can you explain the differences between Vue's keep-alive and router?

Sure! Vue's keep-alive is a built-in component that caches components to preserve their state, while the router is used for navigation between different views or components in a Vue application.

When should I use keep-alive instead of just relying on the router?

You should use keep-alive when you want to maintain the state of a component while navigating away from it, such as in a tabbed interface. The router is more about managing the application's views.

Can keep-alive be used with dynamic routes?

Yes, keep-alive can be used with dynamic routes. You can specify which components to cache based on the route, allowing for efficient state management.

Are there any performance implications of using keep-alive?

Yes, while keep-alive can improve user experience by preserving component state, it can also lead to increased memory usage if too many components are cached.
