Next.js 14

Next.js 14 is a major release of the popular React framework that focuses on dramatically improving developer experience and performance. Here's a breakdown of its key features:

1. Turbopack

The Rust-powered successor to Webpack: Designed specifically for speed, Turbopack serves as the new build tool and bundler in Next.js 14. Blazing-fast development: Offers local server startup speeds 10x faster than Webpack, and up to 20x faster updates with Fast Refresh. This significantly accelerates your development workflow.

2. Improved App Router (formerly App Directory)

Simplifying complex routing and layouts: The App Router introduced in Next.js 13 has received significant upgrades making it more powerful and intuitive for handling nested routes and complex layouts.

3. Server Actions

Data mutations made easy: Server Actions provide a simple way to define API-like functions directly within the App Router, streamlining how you handle interactions that update data (e.g., form submissions). Progressive Enhancement: Supports both traditional forms and modern JavaScript, providing flexibility and enhanced user experiences.

4. Partial Prerendering (Preview)

Hybrid rendering: This feature allows you to prerender a static, lightweight version of a page initially, and then dynamically load and hydrate interactive components as needed. Performance and UX benefits: Delivers a fast initial load while allowing dynamic elements to be incorporated progressively.

5. Next.js Learn
