Next.js, the popular React framework, has released its version 14, bringing a host of new features and improvements that promise to revolutionize web development. In this blog post, we’ll explore the key features of Next.js 14, discuss why you should consider using it, and how it can benefit your projects.

Key Features of Next.js 14

1. Partial Prerendering (Preview)

Next.js 14 introduces Partial Prerendering, a game-changing feature that combines static and dynamic content seamlessly.

How it works:

• Initial static shell is served instantly
• Dynamic content is streamed in on the client
• Fallback UI can be shown while loading dynamic parts

Benefits:

• Faster initial page loads
• Improved SEO with static content
• Better user experience with progressively loaded dynamic content

jsx

// Example of a partially prerendered page
export default function Page() {
  return (
    <div>
      <h1>Welcome to My Store</h1>
      <Suspense fallback={<p>Loading products...</p>}>
        <Products />
      </Suspense>
    </div>
  )
}

2. Server Actions (Stable)

Server Actions, now stable in Next.js 14, allow you to write server-side code directly in your React components.

Benefits:

• Simplifies form handling and data mutations
• Reduces client-side JavaScript
• Improves security by keeping sensitive operations server-side

jsx

// Example of a Server Action
export default function Form() {
  async function handleSubmit(formData: FormData) {
    'use server'
    const name = formData.get('name')
    await saveToDatabase(name)
  }

  return (
    <form action={handleSubmit}>
      <input type="text" name="name" />
      <button type="submit">Submit</button>
    </form>
  )
}

3. Improved Rendering and Caching Model

Next.js 14 refines its rendering and caching model for better performance and developer experience.

Improvements:

• More intuitive caching behavior
• Enhanced static and dynamic rendering options
• Better control over revalidation and data fetching

jsx

// Example of using the new fetch options
async function getData() {
  const res = await fetch('https://api.example.com/data', { next: { revalidate: 3600 } })
  return res.json()
}

export default async function Page() {
  const data = await getData()
  return <div>{data.title}</div>
}

4. Turbopack Improvements (Beta)

Turbopack, Next.js’ Rust-based bundler, sees significant improvements in version 14.

Enhancements:

• Faster build times
• Improved compatibility with npm packages
• Better error reporting

5. Built-in SEO Support

Next.js 14 introduces new built-in components and utilities for improved SEO.

jsx

import { Metadata } from 'next'

export const metadata: Metadata = {
  title: 'My Page Title',
  description: 'Page description',
  openGraph: {
    title: 'My Open Graph Title',
    description: 'Open Graph Description',
    images: ['/og-image.jpg'],
  },
}

export default function Page() {
  return <h1>Welcome to my page</h1>
}
