Next.js 15 brings exciting new features that make building scalable React applications easier than ever. In this article, we'll explore the key improvements and how to leverage them in your projects.
The new App Router has matured significantly, offering improved performance and developer experience. Server Components are now the default, reducing client-side JavaScript and improving initial load times.
One of the most impactful changes is the improved caching strategy. Next.js 15 introduces more granular control over caching, allowing developers to optimize for both static and dynamic content.
Server Actions have also been refined, making it easier to handle form submissions and mutations without setting up API routes. This simplifies the architecture and reduces boilerplate code.
For large-scale applications, the new parallel routes and intercepting routes features enable complex UI patterns like modals and split views without compromising on performance.
We've seen significant improvements in our projects after migrating to Next.js 15, with some clients reporting up to 40% faster page loads and improved Core Web Vitals scores.
