Building applications that scale is one of the biggest challenges in modern web development. In this guide, we'll explore how to architect Next.js applications that can grow from a small startup project to an enterprise-grade platform.

Understanding Next.js Architecture

Next.js provides a powerful foundation for building scalable applications. The App Router, introduced in Next.js 13, offers a file-system based routing system that makes it easy to organize large codebases.

app/layout.tsx
1// app/layout.tsx
2import { Inter } from 'next/font/google'
3
4const inter = Inter({ subsets: ['latin'] })
5
6export default function RootLayout({
7 children,
8}: {
9 children: React.ReactNode
10}) {
11 return (
12 <html lang="en" className={inter.className}>
13 <body>{children}</body>
14 </html>
15 )
16}

Data Fetching Strategies

Next.js offers multiple data fetching strategies, each optimized for different use cases. Understanding when to use Server Components, Client Components, and API routes is crucial for building performant applications.

Pro Tip

Use Server Components by default and only opt into Client Components when you need interactivity or browser APIs.

Performance Optimization

Performance is critical for user experience and SEO. Next.js provides built-in optimizations like automatic code splitting, image optimization, and font optimization. Additionally, you can leverage caching strategies, edge functions, and static generation to further improve performance.
