Top 5 Features in Next.js 14

Introduction

Next.js 14 continues to push the boundaries of React frameworks, focusing on performance and developer experience. Here are some of the standout features.

1. Turbopack

Claimed to be the successor to Webpack, Turbopack offers lightning-fast builds and development server startups. It's written in Rust and designed for incremental builds, which means your changes are reflected almost instantly.

2. Server Actions

Server Actions are now stable, allowing you to run server code directly from your components without creating separate API routes. This simplifies data mutations and makes your code more co-located.

export default function MyComponent() {
  async function myAction() {
    'use server';
    // ... perform some action on the server
  }
 
  return <form action={myAction}><button type="submit">Submit</button></form>;
}

3. Partial Prerendering (Preview)

This experimental feature combines the best of static site generation (SSG) and server-side rendering (SSR). It allows you to serve a static shell of a page instantly, while streaming in the dynamic parts.

4. Improved Metadata API

Managing metadata like title and meta tags is now more flexible. You can even export a dynamic generateMetadata function to handle route-specific metadata.
