Topic Explanation

Next.js extends React with routing, rendering strategies, server components, API endpoints, metadata, image and font optimization, caching, and deployment conventions. Instead of assembling many libraries by hand, you get a framework that handles common production needs while still letting you write React components.

Next.js Code

Next.js

// Next.js gives you pages, layouts, metadata, APIs, and server logic
// in one React project.

export default function HomePage() {
  return (
    <main>
      <h1>Build with Next.js</h1>
      <p>React UI, server rendering, routing, and deployment together.</p>
    </main>
  );
}

Learning Goals

Explain why Next.js is useful beyond plain React.
Identify where routing, rendering, APIs, and optimization fit.
Know the prerequisites: HTML, CSS, JavaScript, React, and basic TypeScript.

Code Notes

Next.js still uses React; it adds framework features around React.
The App Router is the modern routing model based on the app directory.
Server Components can render on the server and send less JavaScript to the browser.

Practice Task

Write a short comparison of React-only SPA routing versus a Next.js app with server rendering and file-based routes.
