How can I improve performance in Vue 3 using lazy loading?

You can improve performance in Vue 3 by implementing lazy loading for components and routes. This means that components are only loaded when they are needed, reducing the initial load time.

What are the best practices for implementing lazy loading in Vue 3?

Some best practices include using dynamic imports for components, leveraging Vue Router's lazy loading for routes, and ensuring that you have proper error handling in place.

Can you show me an example of lazy loading a component?

Sure! You can use the defineAsyncComponent function from Vue to lazy load a component like this:

import { defineAsyncComponent } from 'vue';

const AsyncComponent = defineAsyncComponent(() => import('./MyComponent.vue'));

Are there any performance metrics I should monitor after implementing lazy loading?

Yes, you should monitor metrics like Time to Interactive (TTI), First Contentful Paint (FCP), and overall load times to see the impact of lazy loading.
