Dependency injection (DI) is an implementation of the dependency inversion principle with the aim of separation of concerns by separating the depndency's implementation from the class that's using it. That kind of abstraction makes it possible to have different implementations with the same public methods so the class using it, doesn't need to care which of the implementations is used. This is also especially useful for unit testing.
There are different types of dependency injection:
A backend template using FastAPI, designed to be adaptable and framework-agnostic. Implements Clean Architecture and DDD principles with modular layer separation and dependency inversion for maintainability. Includes session-based authentication with tokens in cookies to manage session IDs and a simple user permissions management system.
