Lazy loading in Angular improves application performance by loading feature modules only when users navigate to specific routes. As the creator of CoreUI with extensive Angular development experience since 2014, I’ve implemented lazy loading in numerous large-scale applications to reduce initial bundle sizes. The most effective approach uses dynamic imports in route configurations to load modules on demand. This pattern dramatically improves initial load times while maintaining full functionality for all application features.

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.

React Suspense provides a powerful way to handle loading states for asynchronous operations like lazy component loading and data fetching. As the creator of CoreUI, a widely used open-source UI library, I’ve used Suspense extensively in React applications to create smooth user experiences. From my 25 years of experience in web development and 11 years with React, the most effective approach is to wrap components that might suspend with a Suspense boundary and provide appropriate fallback UI. This pattern creates declarative loading states and better error handling.

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.
