modern-di is a python dependency injection framework which supports the following:
- Automatic dependency graph based on type annotations
- Also, explicit dependencies are allowed where needed
- Scopes and context management
- Python 3.10+ support
- Fully typed and tested
- Integrations with
aiogram,aiohttp,arq,Celery,FastAPI,FastStream,Flask,gRPC,Litestar,Starlette,taskiq, andTyper - Pytest integration (
modern-di-pytest) — turns any DI dependency into a pytest fixture
Install
uv add modern-di # or: pip install modern-di
Quick Start
import dataclasses
from modern_di import Container, Group, Scope, providers
@dataclasses.dataclass(kw_only=True, slots=True, frozen=True)
class Settings:
database_url: str = "postgresql+asyncpg://localhost/app"
@dataclasses.dataclass(kw_only=True, slots=True)
class UserRepository:
settings: Settings # auto-injected by type
class Dependencies(Group):
settings = providers.Factory(Settings, scope=Scope.APP)
user_repository = providers.Factory(UserRepository, scope=Scope.REQUEST)
with Container(groups=[Dependencies]) as container:
with container.build_child_container(scope=Scope.REQUEST) as request:
repo = request.resolve(UserRepository)
print(repo.settings.database_url)
See the documentation for scopes, lifecycles, finalizers, and framework integrations. modern-di is deliberately conservative — see Design decisions for what it leaves out on purpose, including auto-binding, in-package integrations, and graph rendering.
Usage examples:
- with Litestar - litestar-sqlalchemy-template
- with FastAPI - fastapi-sqlalchemy-template
