The Evolution of Next.js
Next.js started as a simple React framework for server-side rendering (SSR). Over the years, it transformed into a full-stack, production-grade web platform, integrating static site generation (SSG), dynamic routing, API routes, and edge rendering.
Now, with Next.js 15, the framework pushes performance, scalability, and developer experience to an entirely new level — empowering teams to build fast, secure, and intelligent web experiences with minimal configuration.

Turbocharging Performance with Turbopack
One of the biggest highlights of Next.js 15 is Turbopack, the next-generation bundler designed as a successor to Webpack. Built in Rust, Turbopack is incredibly fast — up to 10× faster than Webpack and 700× faster during incremental builds.
This means developers can enjoy near-instant hot reloads, faster builds, and smoother workflows, even in large projects. It's a huge productivity boost that makes development feel effortless.

React Server Components (RSC) — Now More Powerful
Next.js continues to refine its integration with React Server Components, allowing developers to fetch data directly on the server without shipping unnecessary JavaScript to the client.
In Next.js 15, the RSC implementation is more stable and optimized, reducing network overhead and improving page performance — all while keeping the codebase clean and maintainable.
This change makes apps lighter, faster, and more SEO-friendly, aligning perfectly with the future of web performance standards.

Smarter Routing and Layouts
The App Router, first introduced in Next.js 13, has matured beautifully in version 15. It now supports nested layouts, shared state, parallel routes, and loading states more seamlessly than ever.
This allows developers to create complex user experiences — like dashboards or multi-step pages — with clean code and minimal duplication.
In short, routing in Next.js 15 feels natural, organized, and intuitive.
