Next.js

The React Framework for Production

Next.js is a powerful React framework developed by Vercel that enables functionality such as server-side rendering and generating static websites. It provides a complete solution for building production-ready React applications with optimal performance out of the box. Next.js abstracts away complex configurations and provides smart defaults, allowing developers to focus on building features rather than configuring build tools. It has become the go-to choice for React applications that need SEO, performance, and great developer experience.

What is Next.js?

Next.js is a React-based framework created by Vercel that makes it easy to build fast, user-friendly web applications. While React is a library for building user interfaces, Next.js extends React with powerful features like server-side rendering, static site generation, API routes, and more - all with minimal configuration.

Released in 2016, Next.js has grown to become one of the most popular React frameworks, trusted by companies like TikTok, Nike, Uber, and thousands more. It solves many common challenges in React development, particularly around SEO, performance, routing, and deployment.

Key Features & Capabilities

1

Hybrid Rendering Strategies

Support for SSR (Server-Side Rendering), SSG (Static Site Generation), and ISR (Incremental Static Regeneration) in the same application, giving you maximum flexibility for each page.

2

File-based Routing System

Automatic routing based on file structure in the pages or app directory - no configuration needed, just create files and folders to define your application routes.

3

API Routes

Build API endpoints within the Next.js application using serverless functions, enabling full-stack development without a separate backend server.

4

Image Optimization

Automatic image optimization, lazy loading, modern formats (WebP, AVIF), responsive images, and blur placeholders with the next/image component.

5

Automatic Code Splitting

Automatic code splitting for faster page loads - only load JavaScript needed for the current page, reducing initial bundle size significantly.

6

Built-in TypeScript Support

Zero-configuration TypeScript support with automatic type checking, IntelliSense, and type inference for better developer experience.

7

Fast Refresh

Instant feedback on edits with hot module replacement that preserves component state during development, making the development experience incredibly smooth.

8

Edge Runtime & Middleware

Deploy functions to edge locations worldwide for ultra-low latency. Use middleware for authentication, redirects, and request manipulation.

Rendering Strategies

🔄

SSR - Server-Side Rendering

Pages rendered on each request on the server

Best for: Dynamic content, personalized pages, real-time data
📄

SSG - Static Site Generation

Pages pre-rendered at build time

Best for: Content that doesn't change often, blogs, marketing sites
♻️

ISR - Incremental Static Regeneration

Static pages that update in the background

Best for: E-commerce products, news sites, content with updates
💻

CSR - Client-Side Rendering

Pages rendered in the browser like traditional React

Best for: Dashboards, admin panels, user-specific interfaces

Simple Next.js Page Example

app/page.tsx
// Server Component (runs on server by default)
async function getProducts() {
  const res = await fetch('https://api.example.com/products');
  return res.json();
}

export default async function ProductsPage() {
  const products = await getProducts();
  
  return (
    <div className="container mx-auto">
      <h1 className="text-4xl font-bold mb-8">
        Our Products
      </h1>
      <div className="grid grid-cols-3 gap-6">
        {products.map(product => (
          <div key={product.id} className="card">
            <h2>{product.name}</h2>
            <p>${product.price}</p>
          </div>
        ))}
      </div>
    </div>
  );
}

What's happening here?

  • Server Component: Runs on the server, reducing JavaScript sent to client
  • Async/Await: Fetch data directly in the component using async functions
  • Zero Config: No need to set up API routes or data fetching libraries
  • SEO Optimized: HTML is fully rendered on server for search engines
