How can you measure the effectiveness of your lazy loading implementation?
The effectiveness of lazy loading should be measured by analyzing bundle sizes, load times, and performance metrics. Key metrics include: initial bundle size reduction, Time to Interactive improvement, First Contentful Paint, and overall page load time. Tools like Webpack Bundle Analyzer can visualize bundle composition and size, while Chrome's Lighthouse and Performance tabs can measure real-world loading performance. A/B testing different lazy loading strategies with real users can also provide valuable insights into the actual user experience impact.
