Building Scalable Web Applications with Next.js

Next.js provides a powerful toolkit for shipping production-ready applications quickly.

Hybrid Rendering Strategies

Leverage SSR for personalization, SSG for marketing pages, and ISR for content that evolves.

Edge Functions and Middleware

Use edge logic for localization, A/B testing, and auth checks before requests hit your origin.

Observability and Performance

Combine Vercel Analytics or OpenTelemetry with Core Web Vitals tracking to identify regressions early.

Checklist

• Optimize fonts and images with built-in utilities.
• Cache expensive fetches with React cache or SWR.
• Measure performance using Lighthouse and WebPageTest.
