Symfony - separating backend and frontend?

Question

symfony

Good afternoon, please tell me:

1. How to split a symfony project into backend and frontend?
2. How to create independent modules for backend and frontend, which include: controllers, views, settings, etc.?
3. Separation of routing for static pages, controllers, ie:
3.1 For frontend - example.com/test-page - ie if "test-page" for example is not a module controller. then we transfer control to the content controller
3.2 Respectively, routing for backend applications - example.com/backend/controller-name

Answer 1

1. Separate applications.
2. Folders in the project.
