Routing Strategies

File-based routing system.

Route Types:

Rendering Strategies

Static Site Generation

Build-time rendering.

SSG Implementation:

// app/blog/page.tsx
async function getBlogPosts() {
  const res = await fetch('https://api.example.com/posts', {
    cache: 'force-cache' // Static by default
  });
  return res.json();
}

export default async function BlogPage() {
  const posts = await getBlogPosts();

  return (
    <div>
      <h1>Blog</h1>
      {posts.map((post) => (
        <article key={post.id}>
          <h2>{post.title}</h2>
          <p>{post.excerpt}</p>
        </article>
      ))}
    </div>
  );
}

Server-Side Rendering

Request-time rendering.

SSR Implementation:

// app/dashboard/page.tsx
async function getUserData() {
  const res = await fetch('https://api.example.com/user', {
    cache: 'no-store' // Always fresh
  });
  return res.json();
}

export default async function DashboardPage() {
  const user = await getUserData();

  return (
    <div>
      <h1>Welcome, {user.name}</h1>
      <p>Last login: {user.lastLogin}</p>
    </div>
  );
}

Incremental Static Regeneration

Best of both worlds.

ISR Configuration:

// app/products/page.tsx
async function getProducts() {
  const res = await fetch('https://api.example.com/products', {
    next: { revalidate: 3600 } // Revalidate every hour
  });
  return res.json();
}

export default async function ProductsPage() {
  const products = await getProducts();

  return (
    <div>
      <h1>Products</h1>
      {products.map((product) => (
        <ProductCard key={product.id} product={product} />
      ))}
    </div>
  );
}

File-based content.

MDX Configuration:

// contentlayer.config.ts
import { defineDocumentType, makeSource } from 'contentlayer/source-files';

export const Post = defineDocumentType(() => ({
  name: 'Post',
  filePathPattern: `blog/**/*.mdx`,
  contentType: 'mdx',
  fields: {
    title: { type: 'string', required: true },
    date: { type: 'date', required: true },
    description: { type: 'string', required: true },
    image: { type: 'string' },
  },
  computedFields: {
    slug: {
      type: 'string',
      resolve: (post) => post._raw.flattenedPath.replace('blog/', ''),
    },
  },
}));

export default makeSource({
  contentDirPath: 'content',
  documentTypes: [Post],
});

Performance Optimization

Image Optimization

Next.js Image component.

Image Implementation:

import Image from 'next/image';

export function HeroSection() {
  return (
    <section className="hero">
      <Image
        src="/hero-image.jpg"
        alt="Hero background"
        width={1920}
        height={1080}
        priority // Load immediately for LCP
        quality={85}
        placeholder="blur"
        blurDataURL="/hero-blur.jpg"
      />
    </section>
  );
}

type Props = {
  params: { slug: string }
};

export async function generateMetadata({ params }: Props): Promise<Metadata> {
  const post = await getPost(params.slug);

  return {
    title: post.title,
    description: post.description,
    openGraph: {
      title: post.title,
      description: post.description,
      images: [post.image],
      type: 'article',
      publishedTime: post.date,
    },
    twitter: {
      card: 'summary_large_image',
      title: post.title,
      description: post.description,
      images: [post.image],
    },
  };
}

Structured Data

Rich snippets implementation.

JSON-LD Schema:

// components/BlogPostSchema.tsx
export function BlogPostSchema({ post }) {
  const schema = {
    '@context': 'https://schema.org',
    '@type': 'BlogPosting',
    headline: post.title,
    description: post.description,
    image: post.image,
    datePublished: post.date,
    author: {
      '@type': 'Person',
      name: post.author,
    },
    publisher: {
      '@type': 'Organization',
      name: 'Your Company',
      logo: {
        '@type': 'ImageObject',
        url: 'https://example.com/logo.png',
      },
    },
  };

  return (
