Why Use Next.js Over React?

React is powerful, but it only handles the UI part (frontend part), while Next.js enhances React and makes it a full framework.

1. Built-In Routing

React requires React Router.

Next.js has file-based routing, no configuration needed.

2. Better SEO

React is client-side → so there is a problem, so it renders empty HTML.

For SEO purposes, Next.js is better than React because it renders HTML on the server.

3. Server-Side Rendering

Next.js has server-side rendering, while React does not server-side rendering.

4. Built-In API Support

React → needs a separate backend.

Next.js → you can create /api/ routes inside the same project.

5. Performance Optimization

There are many features for optimization in Next.js

1. Automatic lazy loading

2. Image optimization

3. Script optimization

4. Caching & revalidation

6. Faster Development

Next.js is famous for fast development, so you can check details below.

1. App Router

2. Pre-configured Webpack

3. Built-in TypeScript support
