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

Lazy loading in Vue 3 can significantly improve performance. Here are some best practices: 1. Use dynamic imports for components. 2. Implement route-based code splitting. 3. Utilize Vue's built-in async components. 4. Consider using a loading indicator for better user experience.

Can you explain how to implement dynamic imports?

Sure! You can implement dynamic imports using the import() function. For example, instead of importing a component statically, you can do it like this: const MyComponent = () => import('./MyComponent.vue'); This way, the component will only be loaded when it's needed.

What about route-based code splitting?

Route-based code splitting can be achieved by defining routes with dynamic imports. For instance, in your router configuration, you can do: const routes = [{ path: '/my-route', component: () => import('./MyRoute.vue') }]; This loads the component only when the route is accessed.

Are there any libraries that can help with lazy loading?

Yes, libraries like vue-lazyload and vue-lazy can help manage lazy loading of images and components effectively. They provide additional features like placeholders and loading indicators.
