Lazy loading routes in Vue applications significantly improves initial load performance by loading route components only when they’re needed. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented lazy loading in numerous Vue admin dashboards and large-scale applications. From my 25 years of experience in web development and 11 years with Vue, the most effective approach is to use dynamic imports with arrow functions in route definitions. This pattern enables automatic code splitting and optimizes bundle size for better user experience.

Lazy loading routes in React applications reduces initial bundle size and improves performance by loading components only when they’re needed. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented lazy loading in countless React admin dashboards and large-scale applications. From my 25 years of experience in web development and 11 years with React, the most effective approach is to use React.lazy() with Suspense for dynamic imports. This pattern provides automatic code splitting and seamless loading states.

Async components in Vue.js allow you to load components on-demand, reducing initial bundle size and improving application performance. As the creator of CoreUI with over 11 years of Vue.js development experience, I use async components extensively for code splitting and lazy loading in large applications. Async components are particularly useful for routes, modals, and heavy components that aren’t needed immediately.
