Next.js
Next.js is a React-based open-source web development framework created by Vercel. It enables server-side rendering, static site generation, and other performance optimizations for React applications, providing features like file-based routing, API routes, and built-in CSS support. It simplifies building fast, scalable, and SEO-friendly web applications with React.
Developers should learn Next.js when building production-ready React applications that require improved performance, SEO, or server-side capabilities, such as e-commerce sites, blogs, or dashboards. It's particularly useful for projects needing static generation for fast loading or server-side rendering for dynamic content, as it handles these complexities out-of-the-box with minimal configuration.
