What's New in Next.js 14 - Test

Next.js 14 represents a significant step forward in the React ecosystem. In this article, we'll explore the new features and performance improvements that come with this latest version.

App Router Improvements

The App Router, introduced in Next.js 13 and further refined in 14, brings a new routing system that offers:

• Server Components: Server-side rendering by default
• Streaming: Progressive loading of page content
• Suspense: Native React support for loading states

// app/page.tsx
export default function HomePage() {
  return (
    <div>
      <h1>Hello Next.js 14!</h1>
      <Suspense fallback={<Loading />}>
        <AsyncComponent />
      </Suspense>
    </div>
  )
}

Server Actions

Server Actions are a revolutionary feature for form handling and server-side logic:

// app/actions.ts
'use server'

export async function createPost(formData: FormData) {
  const title = formData.get('title')
  const content = formData.get('content')
  
  // Database operations
  await db.post.create({
    data: { title, content }
  })
  
  revalidatePath('/blog')
}

Performance Optimizations

Performance improvements that come with Next.js 14:

1. Turbopack: Fast bundler developed as an alternative to Webpack
2. Partial Prerendering: Selective rendering of page parts
3. Image Optimization: Enhanced image optimization

Conclusion

Next.js 14 provides powerful tools for modern web development. With the maturation of App Router and the addition of Server Actions, developing full-stack React applications has never been easier.

Thanks to these innovations, we can build faster, more efficient, and user-friendly web applications.
