Next.js
Next.js is a React-based open-source web development framework created by Vercel that enables server-side rendering, static site generation, and other advanced features for building fast, scalable web applications. It provides built-in optimizations like image optimization, API routes, and file-system routing, making it a popular choice for modern full-stack development. The framework supports both client-side and server-side rendering, allowing developers to choose the best approach for performance and SEO.
Developers should learn Next.js when building production-ready web applications that require high performance, SEO optimization, and scalability, such as e-commerce sites, blogs, or enterprise dashboards. It is particularly useful for projects needing server-side rendering to improve initial load times and search engine visibility, or static site generation for content-heavy sites. The framework's integrated tooling and deployment options through Vercel simplify development workflows and reduce configuration overhead.
