modern-di-taskiq 2.1.0

Modern-DI integration for taskiq.

Full guide: taskiq integration docs

Installation

uv add modern-di-taskiq      # or: pip install modern-di-taskiq

Usage

setup_di stores the container on broker.state and registers WORKER_STARTUP/WORKER_SHUTDOWN handlers that open/close it, and builds a Scope.REQUEST child container for each task the worker executes. FromDI resolves a provider (or type) into a task parameter — no per-task decorator is needed.

import typing

from modern_di import Container, Group, Scope, providers
from modern_di_taskiq import FromDI, setup_di
from taskiq import InMemoryBroker


class Settings:
    def __init__(self) -> None:
        self.greeting = "hello"


class Greeter:
    def __init__(self, settings: Settings) -> None:   # auto-injected by type
        self._settings = settings

    def greet(self, name: str) -> str:
        return f"{self._settings.greeting}, {name}"


class AppGroup(Group):
    settings = providers.Factory(Settings, scope=Scope.APP, cache=True)
    greeter = providers.Factory(Greeter, scope=Scope.REQUEST)


broker = InMemoryBroker()
setup_di(broker, Container(groups=[AppGroup], validate=True))


@broker.task
async def greet(
    name: str,
    greeter: typing.Annotated[Greeter, FromDI(Greeter)],   # resolve by type
) -> str:
    return greeter.greet(name)

The WORKER_STARTUP/WORKER_SHUTDOWN events fire when the broker's worker process starts and stops, so a script that calls tasks directly (like InMemoryBroker in a test) must drive the container lifecycle itself — e.g. async with broker: .... The per-task Scope.REQUEST child is torn down asynchronously (close_async()), so async REQUEST-scoped finalizers run correctly while factories build synchronously. taskiq.TaskiqMessage is resolvable within DI via the pre-built taskiq_message_provider context provider.
