Next.js

Next.js (created by the massive cloud deployment titan Vercel) is a colossally disruptive, fiercely modern, and massively accelerating framework that completely solved React's biggest problem. React is a 'Client-Side' framework, meaning it is terrible for SEO (Search Engine Optimization) and can be slow to load on mobile devices. Next.js wraps around React and adds "Server-Side Rendering (SSR)." The absolute core differentiator of Next.js is its "Hybrid Rendering and SEO Dominance." With Next.js, the server pre-builds the React HTML and sends a fully formed, blindingly fast webpage to the user. This means Google's search crawlers can read it perfectly. Once loaded, it seamlessly turns back into a highly interactive React application. Because it offers staggering performance, flawless SEO, and an incredibly streamlined developer experience (zero-configuration routing), Next.js is the absolute, unquestioned default framework for modern React developers building e-commerce stores, SaaS marketing sites, and high-traffic blogs.
