How can I use Vue's keep-alive in my application?

You can use Vue's keep-alive component to cache components and preserve their state when switching between them. This is particularly useful for improving performance in applications with multiple views.

Can you give me an example of where this would be beneficial?

Sure! For instance, in a tabbed interface where each tab represents a different component, using keep-alive allows users to switch tabs without losing their input or scroll position.

Are there any limitations I should be aware of?

Yes, keep-alive only caches components that are conditionally rendered. If a component is removed from the DOM, it will not be cached. Also, be mindful of memory usage when caching many components.

How do I implement it in my Vue app?

To implement keep-alive, wrap your dynamic component in the <keep-alive> tag in your template. For example: <keep-alive><component :is="currentComponent"></component></keep-alive>.
