New App Directory Structure in Next.js 13
One of the most significant changes in Next.js 13 is the introduction of the new app directory structure. This new structure offers improved file system routing by allowing developers to manage their app routes more effectively. It paves the way for nested layouts and automatically organizes routes based on their locations in the file system. This improvement is designed to enhance modularity in large-scale applications, making it easier to maintain source code.
Optimized Image Handling with Next.js 13
With Next.js 13, Vercel has further optimized the next/image component, one of the highly appreciated features of the previous versions. The new improvements include enhanced performance through automatic image size and quality optimization. This means users can now load images faster without sacrificing quality, leading to improved page loading times and enhancing overall user experience.

Enhanced Developer Experience with Turbopack
Turbopack, a modern build system introduced with Next.js 13, aims to replace Webpack, offering faster build speeds and improved compilation efficiency. It’s particularly advantageous in development settings where incremental builds and instant updates are crucial. Turbopack leverages Rust’s compiler speed, making it one of the fasted build tools available, thus significantly improving the development lifecycle of large applications.
Support for React Server Components
Next.js 13 fully supports React Server Components, allowing developers to render components on the server to improve user experience. This means that only the necessary logic and views are sent to the client-side, reducing the client-side bundle size. It’s particularly beneficial for rendering initial loads on the server and providing highly performant pages that are more SEO-friendly.
Improved API Routes and Edge Middleware
Next.js 13 continues to excel in its support for server-side functionalities. It has improved API routes, allowing developers to easily create servers on top of Vercel’s infrastructure. Additionally, the introduction of Edge Middleware provides more options for running middleware closer to the user, enabling faster responses and better handling of real-time data.

Refined Internationalization and Routing
Internationalization (i18n) is an important consideration for global apps. Next.js 13 improves its support for localization with advanced routing capabilities. Developers can now define language-specific content and routing more seamlessly, enhancing the delivery of culturally and regionally appropriate user experiences.
