What is Next.js?

Next.js is a powerful React framework created and maintained by Vercel. It extends React's capabilities with features specifically designed for building production-grade applications.

While React is excellent for building user interfaces, it has some limitations for real-world applications:

React Limitations

  1. SEO support
  2. Routing
  3. Server-side rendering
  4. Performance optimization
  5. API routes

Next.js addresses all these challenges with built-in solutions and production-ready features.

Next.js Key Advantages

  1. Server-side Rendering (SSR) - Render pages on the server for better SEO and performance
  2. Static Site Generation (SSG) - Pre-build pages at compile time for blazing-fast load times
  3. File-based Routing - Automatic route creation based on file structure
  4. Built-in API Routes - Create backend endpoints without separate server setup
  5. Automatic Performance Optimization - Image optimization, code splitting, and lazy loading
  6. Easy Deployment - Seamless deployment with Vercel and other platforms

Thanks to these features, Next.js is the go-to choice for building blogs, business websites, eCommerce platforms, and large-scale applications.

Next.js vs React

React is a JavaScript library for building user interfaces. Next.js is a React framework that adds features like server-side rendering, static site generation, and file-based routing.

Feature React JS Next.js
Type UI Library Full React framework
Rendering Client-side rendering (CSR) Server-side rendering (SSR) and static site generation (SSG)
Routing Type Manual routing File-based routing
SEO Weak SEO SEO Friendly
Performance Client-side rendering (CSR) can be slower Server-side rendering (SSR) and static site generation (SSG) are faster

Quick Tip: In short, Next.js is React with superpowers.

Installing Next.js

Next.js can be easily installed using the official `create-next-app` command. This CLI tool sets up a new Next.js project with all necessary configurations and dependencies.

To install Next.js, run the following command:

npx create-next-app@latest

For macOS and Linux

sudo npx create-next-app@latest

Default Setup Questions

During installation, you'll be prompted with the following questions:

  1. Project name: Choose a name for your Next.js project
  2. Use TypeScript? → Yes (recommended for type safety)
  3. Use ESLint? → Yes (for code quality)
  4. Use App Router? → Yes (modern Next.js routing)
  5. Use Tailwind CSS? → Optional (for styling)

Starting Your Next.js Project

After the project is created, navigate to your project directory and start the development server:

cd your-project-name

Now run the development server:

npm run dev

Open your browser and navigate to http://localhost:3000 to see your Next.js application in action.

Congratulations! Your Next.js development environment is now ready. You can start building your application by editing files in the `app` directory.

Conclusion

Next.js transforms React development by making it simpler, faster, and more powerful. It provides everything you need to build modern, production-ready web applications.

With built-in server-side rendering, static site generation, automatic routing, and performance optimization built-in, Next.js is the ideal choice for contemporary web development projects.

If you're already familiar with React, learning Next.js will feel intuitive and will significantly enhance your ability to build scalable, SEO-friendly web applications.
