By creating router instances in separate files (like users.py and posts.py), defining routes with router.get/post decorators, and including them in the main app with prefixes and tags, you achieve better code organization, separation of concerns, and improved documentation structure. The pattern maintains identical URLs and functionality while making codebases more maintainable and scalable for production applications. ## Full article daily.dev links to this article rather than hosting it.
