Next.js: Beyond Just React

Next.js has revolutionized how I build React applications. It's not just a framework; it's a complete solution that handles everything from routing to optimization, making it incredibly powerful for production applications.

Why Next.js is a Game Changer

Full-Stack Capabilities

Next.js bridges the gap between frontend and backend:

• API Routes: Build APIs alongside your frontend
• Server-Side Rendering: Better SEO and performance
• Static Site Generation: Lightning-fast static sites
• Edge Functions: Run code closer to users

Developer Experience

The DX is phenomenal:

# Create a new Next.js app
npx create-next-app@latest my-app --typescript --tailwind --app

# Development server with hot reload
npm run dev

# Production build with optimizations
npm run build

File-Based Routing

No more complex routing configurations:

app/
├── page.tsx              # /
├── about/page.tsx        # /about
├── blog/
│   ├── page.tsx          # /blog
│   └── [slug]/page.tsx   # /blog/[slug]
└── api/
    └── users/route.ts    # /api/users

App Router vs Pages Router

App Router (Recommended)

The new App Router with React Server Components:

// app/page.tsx - Server Component by default
export default async function HomePage() {
  const posts = await fetchPosts(); // Server-side data fetching
  
  return (
    <div>
      <h1>My Blog</h1>
      {posts.map(post => (
        <PostCard key={post.id} post={post} />
      ))}
    </div>
  );
}

Pages Router (Legacy)

The traditional approach:

// pages/index.tsx
import { GetStaticProps } from 'next';

export default function HomePage({ posts }) {
  return (
    <div>
      <h1>My Blog</h1>
      {posts.map(post => (
        <PostCard key={post.id} post={post} />
      ))}
    </div>
  );
}

export const getStaticProps: GetStaticProps = async () => {
  const posts = await fetchPosts();
  return { props: { posts } };
};

Key Features I Love

Image Optimization

Automatic image optimization with the Image component:

import Image from 'next/image';

<Image
  src="/hero.jpg"
  alt="Hero image"
  width={800}
  height={600}
  priority
  placeholder="blur"
/>

Built-in CSS Support

Multiple styling options out of the box:

• CSS Modules: Scoped CSS
• Tailwind CSS: Utility-first CSS
• Sass: CSS preprocessor
• CSS-in-JS: Styled-components, Emotion

Performance by Default

Next.js optimizes everything:

• Code splitting
• Bundle optimization
• Font optimization
• Script optimization

Best Practices I Follow

Performance Optimization

1. Use Image component for all images
2. Implement code splitting with dynamic imports
3. Optimize fonts with next/font
4. Use Suspense boundaries for loading states

SEO & Accessibility

1. Proper meta tags with next/head or metadata API
2. Semantic HTML structure
3. Alt text for all images
4. Keyboard navigation support

Development Workflow

1. TypeScript for type safety
2. ESLint + Prettier for code quality
3. Husky for pre-commit hooks
4. Vercel for deployment

Deployment Options

Vercel (Recommended)

• Zero-config deployment
• Preview deployments for PRs
• Edge functions support
• Built-in analytics

Self-Hosted

• Docker containers
• PM2 for process management
• Nginx reverse proxy
• CDN for static assets
