Simplifying Dynamic Routes in Next.js App Router

[Awais-Asghar]

I really like how the new App Router handles nested layouts and dynamic segments, but I feel like there's room for improvement when dealing with deeply nested dynamic routes.
For example, building paths manually with multiple [slug] or [id] folders can become repetitive and error-prone. It would be great if Next.js provided something like a generatePath() utility, similar to React Router, to compose dynamic URLs based on route patterns.
Curious to know how others are managing this. Any suggestions, tips, or improvements you’ve found?
