Structuring a bigger project with multiple routers
When building a real-world web application, you're likely to have lot of code and logic: data models, API endpoints, and services. Of course, all of those can't live in a single file; we have to structure the project so that it's easy to maintain and evolve.
FastAPI supports the concept of routers. They are "sub-parts" of your API and are usually dedicated to a single type of object, such as users or posts, that are defined in their own file. You can then include them in your main FastAPI app so that it can route it accordingly.
In this section, we'll explore how to use routers and how you can structure a FastAPI project. While this structure is one way to do it, and works quite well, it's not a golden rule and can be adapted to your own needs.
In the code examples repository, there is a folder named chapter3_project, which contains a sample project with this structure: https://github.com...
