🚀 Introduction to Next.js

Next.js is a powerful React framework that has become one of the most popular choices for building modern web applications. Developed by Vercel, it extends the capabilities of React by providing features like server-side rendering (SSR), static site generation (SSG), and API routes, making it a complete solution for both frontend and backend development.

Unlike traditional React apps, where rendering happens entirely on the client side, Next.js allows developers to choose how each page should be rendered. This flexibility improves performance, SEO, and user experience. For example, e-commerce websites can use SSR for dynamic product pages, while blogs can use SSG for faster load times.

Next.js also comes with built-in routing, meaning you don’t need third-party libraries like React Router. File-based routing makes navigation simple — just add a new file in the pages/ directory, and it automatically becomes a route.

Other notable features include API routes (to build serverless functions), Image Optimization (faster image loading), and Internationalization (i18n) support. With its seamless developer experience and production-ready features, Next.js has become the go-to choice for startups, enterprises, and solo developers alike.

🔥 In short, Next.js helps you build fast, scalable, and SEO-friendly web applications with ease.
