Getting Started with Next.js 14: A Complete Guide

Next.js 14 represents a significant milestone in the evolution of React-based web development. This latest version introduces groundbreaking features that make building fast, scalable web applications easier than ever before.

What's New in Next.js 14?

App Router (Stable)

The App Router is now stable and provides a more intuitive way to structure your applications. It leverages React Server Components by default, offering better performance and developer experience.

// app/page.tsx
export default function HomePage() {
  return (
    <div>
      <h1>Welcome to Next.js 14</h1>
      <p>Building the future of web development</p>
    </div>
  );
}

Server Actions

Server Actions allow you to run server-side code directly from your components, eliminating the need for API routes in many cases.

async function createPost(formData: FormData) {
  'use server';
  
  const title = formData.get('title');
  // Save to database
}

Performance Improvements

Next.js 14 includes significant performance improvements:

• Faster Local Development: 53% faster local server startup
• Improved Memory Usage: 22% less memory usage
• Better Tree Shaking: Smaller bundle sizes
