What is Next.js?
Next.js is defined as an open-source React framework designed by Vercel that enables server-side rendering, static site generation, and serverless edge functions.
Detailed Architectural Context
Next.js is the leading framework for modern React application development. Unlike standard single-page apps (SPAs) that render in the client's browser, Next.js prerenders HTML on the server. This results in incredibly fast page loading times (optimizing LCP) and makes it highly crawlable for search engine bots. It supports static site generation (SSG) for pre-rendering pages at build time, server-side rendering (SSR) for dynamic user data, and incremental static regeneration (ISR) to update static content in the background.
