Installation

pip install fastapi_better_di

Usage

# routes.py
from fastapi_better_di import APIRouterDI

from custom_types import MyType

api = APIRouterDI()

@api.get("/")
def handler(my_type: MyType):  # <- DI without Depends()
    return {"my_type": my_type.value}

# app.py
from fastapi_better_di import FastAPIDI

from custom_types import MyType

app = FastAPIDI()

# Register types for DI
app.dependency_overrides[MyType] = lambda: MyType(123)

def register_routers():
    from routes import api

    app.include_router(router=api)

register_routers()

How it works

fastapi-better-di simply patch the handler function and add = Depends(func) as the default argument
