Simple Flask app in Python that fetches messages from a Telegram channel using Telethon and displays them as a scrolling marquee in the browser.

Create .env file with your own admin password and secret key:

ADMIN_PASSWORD="[YOUR_SECURE_PASSWORD]"
SECRET_KEY="[YOUR_VERY_SECRET_KEY]"

Install packages:

pip3 install -r requirements.txt

Run the app:

python3 site.py

If you are running this app on the server, you would need to copy .env file to that server first.

Open the Admin page http://127.0.0.1:8000/admin and add your Telegram API credentials and Channel ID (your credentials will be stored in a local database). Your admin password is the string that you exported to ADMIN_PASSWORD environment variable from .env file, please keep it secure.

The first time you access Telegram API with your credentials Telegram will ask you to enter a confirmation code and the user_session.session file will be created. Please copy this file to the server where you plan to deploy this app if you don't want to enter the confirmation code again.

Just open http://127.0.0.1:8000 to see the scrolling marquee, it will update automatically every 60 seconds, fetching all messages from your Telegram channel using API credentials that you configured on Admin page.
