Bundling Frontend — Optimisation & Deployment

Optimize frontend bundle size in a Next.js application by configuring code splitting via dynamic imports, enabling Tailwind CSS purging, and using tree-shakeable icons. This reduces initial JavaScript payloads and improves load times.

The best way to prevent font flash of unstyled text during page load is implementing a zero-FOUT font loading strategy using `next/font`. This ensures fonts load efficiently without causing layout shifts or unstyled text flashes.

Code splitting improves Lighthouse scores for animation-heavy web apps by dynamically importing large scenes or libraries, which reduces the initial JavaScript payload. This significantly lowers First Contentful Paint and hydration costs.

You do not strictly need Tailwind, but leveraging Tailwind purging alongside CSS-only animations is the implemented strategy for minimizing CSS payloads. This approach ensures smaller file sizes for performance-critical web applications.

You should use dynamic imports for asset optimization in Next.js when deploying complex, interactive landing pages that require fast load times on slow networks. This defers heavy library loading until needed, protecting performance metrics.
