server telegram bot example

Test async bot on own laptop

prepare repo

clone echo_bot:

git clone https://github.com/ABaaaC/echo_bot_example.git

create own .env file with variables, how to get BASE_WEBHOOK_URL see in ngrok chapter:

BOT_TOKEN = #
BASE_WEBHOOK_URL = # "https://something-from-ngrok.ngrok-free.app"
WEBHOOK_PATH = "/webhook_echo"
WEBHOOK_SECRET = BOT_TOKEN
WEB_SERVER_HOST = "127.0.0.1" # for ngrok
WEB_SERVER_PORT = 8080 # for ngrok

conda environment

create conda environment

conda create --name echo_env
conda activate echo_env
conda install python=3.11.4
conda install pip=23.2.1 
pip install -r requirements.txt

python-dotenv
aiogram==3.0.0
gunicorn==21.2.0

ngrok

create account in ngrok.com

make new domain

go to the “Setup and Instalation”, choose pown platform

for Mac: in terminal install ngrok and create config for ngrok:

brew install ngrok/ngrok/ngrok
ngrok config add-authtoken $NGROK_TOKEN

run the node

ngrok http --domain=$DOMAIN $PORT

set webhook in browser, more here:

https://api.telegram.org/bot{$TELEGRAM_TOKEN}/setWebhook?url={$DOMAIN}/webhook_echo/{$TELEGRAM_TOKEN}

/webhook_echo/ in url was set in my bot.py

run

run bot using gunicorn, bot means echo_bot.py in the current directory:

gunicorn echo_bot:app -b 127.0.0.1:$PORT -k aiohttp.Gunicor
nWebWorker

Submit bot to the server (free yet)

Render

register on render.com

in dashboard: New → Web Service

connect github repo

edit Configure (suitable for my case):

• region: frankfurt (could be any)
• root: empty
• build command: pip install -r requirements.txt
• start command: gunicorn echo_bot:app -b 0.0.0.0:8443 -k aiohttp.GunicornWebWorker
• free plan

add env variable PYTHON_VERSION = 3.11.4

create service → it does not work yet.

We should add .env file in Enviroment → Secret Files

like here (be careful with ports):

BASE_WEBHOOK_URL will be changed to https://echo-bot-example.onrender.com for example

Telegram hook

create new telegram api hook like here.

it’s better to use different bots for test and release, so you need new TELEGRAM_TOKEN (and edit .env file in Render)

If you use the same bot for test and release, than you should every time set new webhook

Actually, that’s all🫡
