Question 1

What is Next.js?

Accepted Answer

Next.js is a React framework developed by Vercel that adds server-side rendering, static site generation, API routes, file-based routing, and full-stack capabilities to React. It is the most popular production-ready React framework.

Question 2

When should I choose Next.js over plain React?

Accepted Answer

Choose Next.js when SEO matters, when you need server-side rendering for performance, when you want a full-stack solution, or when you're building a production SaaS or marketing site. Plain React (Vite SPA) is sufficient for internal tools or apps where SEO doesn't matter.

Question 3

What is the App Router in Next.js?

Accepted Answer

The App Router is Next.js 13+ feature that uses React Server Components by default, provides nested layouts, streaming, and co-located server/client code. It replaces the older Pages Router and is the recommended approach for all new Next.js projects.

Question 4

What are React Server Components?

Accepted Answer

React Server Components (RSC) run on the server, can access databases and APIs directly, and send only the rendered HTML to the client. They reduce client-side JavaScript bundle size and improve performance. Next.js App Router uses Server Components by default.

Question 5

What is the difference between SSR, SSG, and ISR in Next.js?

Accepted Answer

SSR (Server-Side Rendering) generates pages on each request for always-fresh content. SSG (Static Site Generation) pre-renders pages at build time for maximum performance. ISR (Incremental Static Regeneration) pre-renders pages but revalidates them on a schedule. Stacklyn chooses the right strategy per page based on content freshness requirements.

Question 6

Does Stacklyn build Next.js SaaS products?

Accepted Answer

Yes. SaaS development with Next.js is a core Stacklyn specialization. We build multi-tenant SaaS apps with authentication (Clerk/Auth.js), subscription billing (Stripe), team workspaces, role-based access control, and analytics.

Question 7

How does Next.js help with SEO?

Accepted Answer

Next.js improves SEO through: server-rendered HTML that's immediately indexable, the Metadata API for canonical tags, OG images, and structured data, Next/Image for image optimization, and fast loading speeds that improve Google Core Web Vitals scores.

Question 8

Does Stacklyn optimize Core Web Vitals for Next.js?

Accepted Answer

Yes. Core Web Vitals optimization is standard in all Stacklyn Next.js projects. We target: LCP under 2.5s, FID/INP under 200ms, and CLS under 0.1. Optimization includes lazy loading, image optimization, code splitting, and caching.

Question 9

Can Stacklyn deploy Next.js on AWS instead of Vercel?

Accepted Answer

Yes. We deploy Next.js on AWS using ECS containers, Lambda@Edge, or EC2 with Nginx. This is preferred when you need more control over infrastructure, custom networking, or cost optimization at scale.

Question 10

Does Next.js support TypeScript?

Accepted Answer

Yes. Next.js has built-in TypeScript support. Stacklyn always uses TypeScript with Next.js for type-safe components, API routes, server actions, and database queries.

Question 11

What is Next.js middleware and when is it used?

Accepted Answer

Next.js middleware runs before a request is completed, enabling authentication checks, redirects, A/B testing, and geo-routing at the edge. It executes on Vercel's Edge Network for sub-millisecond latency.

Question 12

Does Stacklyn integrate headless CMS with Next.js?

Accepted Answer

Yes. We integrate headless CMS platforms like Sanity, Contentful, Strapi, and Notion with Next.js. Content editors manage content via the CMS, and Next.js fetches and renders it with SSG/ISR for optimal performance.

Question 13

What is the cost of Next.js development at Stacklyn?

Accepted Answer

Next.js development starts at ₹2 lakh for simple apps. Full Next.js SaaS products range from ₹5–25 lakh. Marketing sites and landing pages start at ₹1 lakh. We provide fixed-price quotes after discovery.

Question 14

Does Stacklyn use Prisma with Next.js?

Accepted Answer

Yes. Prisma is our preferred ORM for Next.js applications using PostgreSQL. It provides type-safe queries, schema migrations, and excellent TypeScript integration. Drizzle ORM is an alternative for performance-critical queries.

Question 15

Can Stacklyn migrate my existing app to Next.js?

Accepted Answer

Yes. We migrate from Create React App, Gatsby, or legacy Pages Router to Next.js App Router. Migrations are done incrementally to minimize risk and disruption.

Question 16

Does Next.js work with authentication?

Accepted Answer

Yes. Authentication options for Next.js include Clerk (hosted auth with UI components), Auth.js (open-source, self-hosted), NextAuth, or custom JWT implementation. Stacklyn recommends Clerk for most projects for its developer experience.

Question 17

How does Stacklyn handle environment variables in Next.js?

Accepted Answer

Environment variables in Next.js are managed via .env files (local), Vercel environment variables (production), or AWS Secrets Manager (self-hosted). Public variables use NEXT_PUBLIC_ prefix and server-only variables remain unexposed to the client.

Question 18

Does Stacklyn build e-commerce sites with Next.js?

Accepted Answer

Yes. We build e-commerce sites with Next.js + Stripe for custom platforms, or Next.js + Shopify/Medusa for headless commerce. Next.js's SSG is ideal for product catalog pages with thousands of products.

Question 19

What monitoring does Stacklyn set up for Next.js apps?

Accepted Answer

We configure Vercel Analytics or Google Analytics for user tracking, Sentry for error monitoring, Datadog or New Relic for performance monitoring, and custom dashboards for business metrics.

Question 20

Accepted Answer
