Scalability is not just about traffic-your Next.js app also needs to handle more features and more developers. This post shows practical patterns for structuring routes, separating server logic, using caching, and organizing UI and types so the codebase can grow without collapsing.
1Clarifies three dimensions of scalability: traffic, features, and team.
2Shows how to structure the App Router by domain sections (marketing, app, admin) and move reusable code into src.
3Demonstrates clean separation between server components, server utilities, and client components.
4Explains how to mix SSG/ISR/SSR and revalidate options to handle different kinds of data at scale.
5Covers database and external service considerations, plus patterns for UI primitives and feature modules to support team growth.
