FastAPI - dependency inside Middleware?

After struggling to get dependencies inside of middleware I learned that you can make global dependencies at the app level. I used this to set the user on every single route of the application without needing Depend on getting the user on each route.






        
from fastapi import Depends, FastAPI, Request


def get_db_session():
    print("Calling 'get_db_session(...)'")
    return "Some Value"


def get_current_user(session=Depends(get_db_session)):
    print("Calling 'get_current_user(...)'")
    return session


def recalculate_resources(request: Request, current_user=Depends(get_current_user)):
    print("calling 'recalculate_resources(...)'")
    request.state.foo = current_user


app = FastAPI(dependencies=[Depends(recalculate_resources)])


@app.get("/")
async def root(request: Request):
    return {"foo_from_dependency": request.state.foo}
