Next.js Development

Why do people pick Next.js over plain React? Mostly for two things — SEO and speed. Next.js renders pages on the server or at build time, so search engines see fully-formed content instead of a blank page waiting on JavaScript to load, and users get a site that feels instant even on a slow connection. I reach for Next.js when a project genuinely needs to rank on Google or load fast — marketing sites, content platforms, or full web apps where performance isn't optional. That includes API routes, image optimization, and deployment tuned for real traffic, not just a good Lighthouse score in a demo. The core problem Next.js solves is one plain React can't on its own: client-side rendering means the browser has to download and execute JavaScript before any real content appears, which is bad for both SEO (search engines historically struggle with content that isn't in the initial HTML) and perceived speed (users stare at a blank page or spinner longer than they should). Next.js fixes this with a choice of rendering strategies — Server-Side Rendering for pages that need fresh data on every request, Static Site Generation for content that doesn't change often, and Incremental Static Regeneration for a middle ground where static pages update in the background without a full rebuild. Picking the right strategy per page matters more than defaulting to one approach across an entire site. A marketing homepage might be fully static for maximum speed, a product catalog might use ISR to stay fresh without hammering the database on every visit, and a user dashboard might need full SSR or client-side fetching since the content is genuinely dynamic and user-specific. I make that call page by page, not project-wide. Beyond rendering strategy, I build with the App Router, TypeScript for type safety across the stack, and Tailwind CSS for styling, with attention to the details that actually move the needle on Core Web Vitals — proper image optimization through next/image, font loading that doesn't cause layout shift, and API routes structured cleanly when the project needs backend logic without a separate server. Deployment is typically on Vercel for native platform support, though I deploy to AWS or other providers when a project's requirements call for it.
