What are the best practices for lazy loading in Vue.js?

Lazy loading in Vue.js helps improve performance by loading components only when needed. Some best practices include using dynamic imports, leveraging Vue Router's route-based code splitting, and implementing a loading state for better user experience.

Can you explain how to implement dynamic imports?

Sure! You can use dynamic imports with the import() function. For example, in your component, you can do: const MyComponent = () => import('./MyComponent.vue'); This will load MyComponent only when it's needed.

What about using lazy loading with images?

For images, you can use the v-lazy directive from libraries like vue-lazyload. This allows images to load only when they enter the viewport, improving initial load time.

Are there any performance metrics I should monitor?

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