aiogram3-di 2.0.0

Dependency Injection implementation for aiogram 3.

Example of usage

import logging
from os import getenv
from typing import Annotated

from aiogram import Router, Bot, Dispatcher
from aiogram.types import Message, User
from aiogram3_di import setup_di, Depends

router = Router()


def get_user_full_name(event_from_user: User) -> str:
    return event_from_user.full_name


@router.message()
async def start(
        message: Message, full_name: Annotated[str, Depends(get_user_full_name)]
) -> None:
    await message.answer(f"Hi {full_name}")


def main() -> None:
    logging.basicConfig(level=logging.INFO)

    bot = Bot(token=getenv("BOT_TOKEN"))

    dp = Dispatcher()

    dp.include_router(router)

    setup_di(dp)

    dp.run_polling(bot)


if __name__ == "__main__":
    main()

Handler Dependencies.

You can use Depends in the flags parameter of the handler, for example:

flags={"dependencies": [Depends(verify_user)]}

Details

It is inspired by FastAPI.

If you define a normal def, your function will be called in a different thread.
