What are the best practices for using Vue Lazyload with async components?

When using Vue Lazyload with async components, consider the following best practices: 1. Use the v-lazy directive for images and components. 2. Ensure that your async components are properly chunked to optimize loading. 3. Implement a loading placeholder to enhance user experience. 4. Monitor performance and adjust lazy loading thresholds as needed.

Can you explain how to implement a loading placeholder?

To implement a loading placeholder, you can use a simple <div> or an image that displays while the async component is loading. For example, wrap your async component in a <template v-if="isLoading"> block that shows the placeholder until the component is fully loaded.

What are the performance implications of lazy loading?

Lazy loading can significantly improve performance by reducing the initial load time of your application. It allows you to load only the components that are needed at the moment, which decreases the amount of JavaScript that needs to be parsed and executed upfront.

Are there any common pitfalls to avoid?

Yes, some common pitfalls include not properly handling the loading state, overusing lazy loading for small components, and failing to test the user experience across different devices and network conditions.
