optimize

To fix a slow single-page app, you must identify performance bottlenecks like large bundle sizes and heavy images, then apply code splitting, lazy loading, and image optimization to lower Time to Interactive and improve runtime performance.

The best way to measure Core Web Vitals is running a performance audit that captures LCP, FID, and CLS metrics alongside bundle size, providing a baseline to identify loading and rendering bottlenecks across your web application.

Lazy loading improves web interface performance by deferring the download of non-critical resources until they are needed, directly reducing initial bundle size and accelerating loading speed for faster user interactivity.

Yes, you can use code splitting to reduce your web app's bundle size by breaking your JavaScript into smaller chunks, which minimizes the initial payload and significantly improves loading and Time to Interactive metrics.

If frontend animations are not rendering smoothly, you need to identify runtime performance bottlenecks in your rendering pipeline and apply CSS optimization and animation strategies to achieve smoother visual execution.

You need to optimize font loading for your website when performance audits indicate that custom fonts are delaying text rendering or shifting layout, negatively impacting your Core Web Vitals and overall loading speed.
