Basic initialization

import asyncio

from vk_teams_async_bot.bot import Bot
from vk_teams_async_bot.events import Event
from vk_teams_async_bot.filter import Filter
from vk_teams_async_bot.handler import CommandHandler

app = Bot(bot_token="TOKEN", url="URL")


async def cmd_start(event: Event, bot: Bot):
    await bot.send_text(chat_id=event.chat.chatId, text="Hello")


app.dispatcher.add_handler(
    CommandHandler(callback=cmd_start, filters=Filter.command("/start")),
)


async def main():
    await app.start_polling()


if __name__ == "__main__":
    asyncio.run(main())

Send messages

Without formatting

async def cmd_start(event: Event, bot: Bot):
    await bot.send_text(chat_id=event.chat.chatId, text="Hello")
    await bot.send_text(chat_id=event.chat.chatId, text="<b>Hello</b>")
    await bot.send_text(chat_id=event.chat.chatId, text="*Hello*")

Result:

async def cmd_start(event: Event, bot: Bot):
    text = \
        """
        *hello*
        _hello_
        __hello__
        """

    await bot.send_text(
        chat_id=event.chat.chatId, text=text, parse_mode=ParseMode.MARKDOWNV2
    )

Result:

InlineKeyboard

from vk_teams_async_bot.constants import StyleKeyboard
from vk_teams_async_bot.handler import CommandHandler
from vk_teams_async_bot.helpers import InlineKeyboardMarkup, KeyboardButton

def keyboad_start_menu():
    keyboard = InlineKeyboardMarkup(buttons_in_row=3)
    keyboard.add(
        KeyboardButton(
            text="🛠 first button",
            callback_data="cb_one",
            style=StyleKeyboard.PRIMARY,
        ),
        KeyboardButton(
            text="🕹 second button",
            callback_data="cb_two",
            style=StyleKeyboard.BASE,
        ),
        KeyboardButton(
            text="🌐 third button",
            url="https://example.com/",
            style=StyleKeyboard.ATTENTION,
        ),
    )
    return keyboard


async def cmd_start(event: Event, bot: Bot):
    text = """hello"""
    await bot.send_text(
        chat_id=event.chat.chatId,
        text=text,
        inline_keyboard_markup=keyboad_start_menu(),
    )

You can specify the number of buttons in a row InlineKeyboardMarkup(buttons_in_row=1)

Middleware

You can check the incoming request or add any data for further use in handlers.

Check the access rights of the user or group

from vk_teams_async_bot.middleware import Middleware

class AccessMiddleware(Middleware):
    async def handle(self, event, bot):
        allowed_chats = [
            "[e-mail]",
        ]

        if event.chat.chatId not in allowed_chats:
            text = f"Does not have rights to use the bot - {event.chat.chatId}"
            await bot.send_text(chat_id=event.chat.chatId, text=text)
            raise PermissionError(text)
        return event

async def main():
    app.dispatcher.middlewares = [AccessMiddleware(),]

    await app.start_polling()

if __name__ == "__main__":
    asyncio.run(main())

Add a user or group role

Let's imagine that we have a data source on our side with roles or user rights that we want to use to access a specific menu or handler

from vk_teams_async_bot.middleware import Middleware

class UserRoleMiddleware(Middleware):
    async def handle(self, event, bot):
        roles = {
            "[e-mail]": "admin",
        }
        event.middleware_data.update({"role": roles.get(event.chat.chatId)})
        logger.debug(
            "UserRoleMiddleware role for {chatID} - {role}".format(
                chatID=event.chat.chatId, role=event.middleware_data.get("role")
            )
        )
        return event


async def main():
    app.dispatcher.middlewares = [UserRoleMiddleware(),]

    await app.start_polling()

if __name__ == "__main__":
    asyncio.run(main())
