Introduction to Next.js 14

Next.js 14 represents a significant leap forward in web development, introducing groundbreaking features that make building modern applications faster and more intuitive than ever before.

The New App Router

The App Router is a paradigm shift in how we structure Next.js applications. Unlike the traditional Pages Router, it leverages React Server Components by default, enabling better performance and a more streamlined developer experience.

// app/page.tsx
export default function Home() {
  return 
Welcome to Next.js 14
}

Server Components by Default

All components in the app directory are Server Components by default. This means they render on the server, reducing JavaScript bundle sizes and improving initial page load times. To use Client Components, simply add the 'use client' directive at the top of your file.

Improved Performance

Next.js 14 introduces Turbopack for faster local development and improved build times. With incremental bundling and optimized hot module replacement, your development workflow becomes significantly more efficient.

Server Actions

Server Actions allow you to mutate data directly from your components without creating API routes. This simplifies form handling and data mutations while maintaining security.

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

Next.js 14 is production-ready and used by thousands of companies worldwide. Start building your next project with these powerful new features today!
