**aiogram** modern and fully asynchronous framework for [Telegram Bot API](https://core.telegram.org/bots/api) written in Python 3.7 with [asyncio](https://docs.python.org/3/library/asyncio.html) and [aiohttp](https://github.com/aio-libs/aiohttp). It helps you to make your bots faster and simpler.


## Features

- Asynchronous ([asyncio docs](https://docs.python.org/3/library/asyncio.html), [PEP-492](https://www.python.org/dev/peps/pep-0492/))
- [Supports Telegram Bot API v{!_api_version.md!}](api/index.md)
- [Updates router](dispatcher/index.md) (Blueprints)
- Finite State Machine
- [Middlewares](dispatcher/middlewares.md)
- [Replies into Webhook](https://core.telegram.org/bots/faq#how-can-i-make-requests-in-response-to-updates)


!!! note
    Before start using **aiogram** is highly recommend to know how to work with [asyncio](https://docs.python.org/3/library/asyncio.html).

## Example

Simple usage
```python3 
from aiogram import Bot, Dispatcher, types
from aiogram.dispatcher.handler import MessageHandler

TOKEN = "42:TOKEN"
dp = Dispatcher()


@dp.message(commands=["start"])
class MyHandler(MessageHandler):
    """
    This handler receive messages with `/start` command
    """

    async def handle(self):
        await self.event.answer(f"<b>Hello, {self.from_user.full_name}!</b>")


@dp.message(content_types=[types.ContentType.ANY])
async def echo_handler(message: types.Message, bot: Bot):
    """
    Handler will forward received message back to the sender
    """
    await bot.forward_message(
        from_chat_id=message.chat.id, chat_id=message.chat.id, message_id=message.message_id
    )


def main():
    bot = Bot(TOKEN, parse_mode="HTML")
    dp.run_polling(bot)


if __name__ == "__main__":
    main()
```
