Next.js Architecture That Stays Healthy as Your Product Grows

Next.js gives you many building blocks: routing, server components, caching, and more. The challenge is deciding how to put them together in a way that will still make sense a year from now.

We also touch on localization, environment separation, and how to make the most of the App Router in real projects.
