Telegram Exception Alerts

THIS LIBRARY HAS BEEN EXTENSIVELY TESTED AND IS CONSIDERED VERY STABLE: IT WORKS FINE AND HAS NO EXTERNAL DEPENDENCIES. SO NO FUTURE UPDATES ARE EXPECTED UNLESS I HAVE SOME VERY BRIGHT IDEA ABOUT IT.

A very lightweight library for sending exception details to Telegram using a decorator. It uses no external dependencies.

Installation

pip install telegram-exception-alerts

or

poetry add telegram-exception-alerts

Usage

After you initialize the alerter instance you can attach the decorator to any function. If it raises an exception information will be send to the chat specified in chat_id (don't forget that if you want to send notification to a channel you need to prepend that chat_id with -100).

Normal initialization

from telegram_exception_alerts import Alerter

tg_alert = Alerter(bot_token='YOUR_BOT_TOKEN', chat_id='YOUR_CHAT_ID')

@tg_alert
def some_func_that_can_raise_an_exception():
    raise RuntimeError('this is an exception')

Initialization from environment (recommended)

You can also initialize the alerter from environment variables. This is the recommended way because it will make sure you're not committing sensitive information to the repo.

• ALERT_BOT_TOKEN - your bot token
• ALERT_CHAT_ID - your chat id to receive notifications

from telegram_exception_alerts import Alerter

tg_alert = Alerter.from_environment()

@tg_alert
def some_func_that_can_raise_an_exception():
    raise RuntimeError('this is an exception')

Here's what a telegram message from an example above looks like:

Sending messages

You can also use the Alerter as a simple way to send messages to Telegram:

from telegram_exception_alerts import Alerter

tg_alert = Alerter.from_environment()

tg_alert.send_message(chat_id=111222333, text='Message text')

For real bot programming I highly recommend the excellent python-telegram-bot library.
