FAQPage Schema

How do I build a high-performance Next.js 14 app with App Router?▼

App Router in Next.js 14 uses file-based routing with server components by default, enabling fast page loads through server-side rendering, automatic code splitting, and native fetch caching. Set up a root layout, create routes as nested folders, and use server actions for mutations to achieve Core Web Vitals > 90.

What's the difference between Pages Router and App Router in Next.js?▼

App Router replaces Pages Router with modern file-based structure, server components as default, and streaming UI support. App Router enforces TypeScript strict mode, native fetch with caching, and the Metadata API for SEO, delivering better performance and production-ready patterns out of the box.

How do I optimize images and SEO in a Next.js 14 app?▼

Use next/image for automatic optimization—responsive sizing, lazy loading, and modern formats reduce Core Web Vitals impact. Apply the Metadata API to inject structured data and canonical tags on each page, ensuring search engines index content correctly and pages rank higher.

Can I use server actions for form submissions and data mutations in Next.js?▼

Server actions let you write backend logic directly in server components, handling form submissions and mutations without separate API routes. They integrate with App Router caching and revalidation, keeping full-stack pages fast and reducing client-side JavaScript.

What deployment options work best for Next.js 14 apps?▼

Vercel provides first-class Next.js 14 support with zero-config deployments and automatic optimizations. Self-hosting is also supported—build once, deploy to any Node.js environment, and configure ISR and streaming revalidation to maintain performance at scale.

How does data fetching and caching work in App Router?▼

Next.js 14 uses native fetch with automatic caching by default—responses cache at build time. Use revalidateTag() or revalidatePath() for incremental static regeneration (ISR), and enable streaming to progressively render pages while data fetches, improving perceived performance.
