The original title is "Next.js Dynamic Imports & Lazy Loading: The Complete Guide (2026)"

Short summary

Next.js dynamic imports split heavy components into separate chunks that load only when rendered, reducing initial bundle size and improving Time to Interactive. Use next/dynamic with the loading prop for loading states, or ssr: false for browser-only components. Benchmark the impact on Core Web Vitals, especially for common offenders like Recharts (200-400KB) or rich text editors (300-600KB).
