Configure your FastAPI app with the Pypendency class:

Pypendency(
    app,
    "_dependency_injection",
    [os.path.dirname(os.path.abspath(__file__))],  # ["src"],
)

A sample controller:

# get_user_controller.py
class GetUserController:
    def get(self) -> dict:
        return {"user": "John Doe"}

# _dependency_injection/get_user_controller.yaml
GetUserController:

On your router:

from fastapi import APIRouter
from fastapi import Request
from fastapi_pypendency import ContainerBuilder
from fastapi_pypendency import get_container
from get_user_controller import GetUserController


router = APIRouter(
    prefix="/user",
    tags=["user"],
    dependencies=[],
    responses={404: {"description": "Not found"}},
)

@router.get("/")
def get_user(request: Request):
    container: ContainerBuilder = get_container(request)
    controller: GetUserController = container.get("GetUserController")
    return controller.get()
