React has been the foundation of modern frontend development for years, but as applications grow, developers often need tools that go beyond a simple UI library. That’s where Next.js comes in. It builds on top of React and solves some of the framework’s biggest real-world challenges—performance, routing, SEO, and developer experience.
In this post, I’ll break down why more React developers are shifting toward Next.js and why it might be the right move for your next project.
1. Built-in Routing (No More react-router Setup)
React doesn’t include a router out of the box—you have to install react-router and configure everything yourself.
Next.js eliminates this by using a file-based routing system:
/pages/index.js → Home
/pages/about.js → About
/pages/products/[id].js → Dynamic route
No configuration. No boilerplate. Just create files and go.
2. Server-Side Rendering & Static Generation
React apps are typically client-side rendered, which isn’t ideal for SEO and can slow down initial page load.
Next.js gives you:
SSR (getServerSideProps)
SSG (getStaticProps)
Incremental Static Regeneration
App Router (Server Components)
This makes dynamic apps feel faster and more SEO-friendly right out of the box.
Traditional React applications are client-side rendered, which can slow down initial load times and weaken SEO.
Next.js provides multiple rendering strategies:
- SSR (Server-Side Rendering)
- SSG (Static Site Generation)
- ISR (Incremental Static Regeneration)
- React Server Components via App Router
This flexibility ensures better performance and significantly improved SEO.
3. The App Router Advantage
The Next.js App Router introduces a more modern and structured way to build applications:
- Server and Client Components
- Nested layouts
- Streaming + Suspense support
- Built-in SEO & metadata handling
This architecture promotes cleaner code and better performance.
