Next.js and React Development

Next.js and React development centers on using the React library within the structured environment of the Next.js framework to build modern, full-stack web applications. While React provides the core capability for creating dynamic and interactive user interfaces through its component-based architecture, Next.js extends this by providing a robust set of production-ready features out-of-the-box. These include file-system based routing, server-side rendering (SSR), static site generation (SSG), and built-in API routes, which together enable developers to create highly performant, scalable, and SEO-friendly applications with a streamlined development experience.
