Why App Router Matters

For developers who've been working with Pages Router, the shift to App Router brings several game-changing benefits:

Modern Architecture Alignment

App Router embraces the latest Next.js patterns, including server components, streaming, and improved data fetching. This means your XM Cloud projects leverage cutting-edge web technologies right out of the box.

Performance Improvements

By reducing the amount of JavaScript that runs in the browser and embracing server-side rendering patterns, applications built with App Router deliver faster page loads and better Core Web Vitals scores.

Cleaner Code Structure

The migration to the app/ directory brings more intuitive file organization, making projects easier to navigate and maintain. Data fetching becomes more declarative, and the separation of concerns between server and client components creates cleaner architecture.

Better Developer Experience

With server components as the default, developers write less boilerplate code and the framework handles more optimization automatically. This leads to faster development cycles and fewer potential bugs.
