Building Scalable Web Apps with Next.js 13 App Router

The Next.js App Router introduced in version 13 fundamentally changed how we build React applications. In this article, we explore server components, data fetching patterns, and how to structure your application for performance and maintainability. Server components allow you to render parts of your application on the server, reducing the JavaScript shipped to the client. This has massive implications for performance, especially on content-heavy pages. We'll cover the key patterns we use at Asidotech to ship production applications: streaming, suspense boundaries, incremental static regeneration, and how to mix server and client components effectively.
