React + Next.js Basics

React is a UI library, and Next.js is a React framework that provides building blocks for web applications.

Why Next.js?

• Server-Side Rendering (SSR): Improves SEO and initial load performance.
• Routing: Built-in file-system based routing (App Router).
• API Routes: Build your backend directly within your Next.js app.
• Optimization: Automatic image, font, and script optimizations.

Getting Started

To create a new Next.js application:

npx create-next-app@latest

Follow the prompts to configure your project (we recommend using TypeScript, Tailwind CSS, and the App Router).

Basic Component

export default function HelloWorld() {
  return (
    <div className="p-4 bg-gray-100 rounded">
      <h1 className="text-xl font-bold">Hello World!</h1>
    </div>
  );
}
