Website Registration Monitor

A Python application that monitors website registration pages and sends Telegram notifications when registration status changes.

Features

• Monitors multiple URLs for registration availability
• Sends real-time alerts via Telegram
• Comprehensive error handling and logging
• Configurable check intervals
• Headless Chrome browser automation

Refactoring Changes

This application has been completely refactored with the following improvements:

Security

• Removed hardcoded credentials - Now uses environment variables
• Added .env.example template for secure configuration

Code Quality

• Object-oriented design - Introduced TelegramNotifier and WebsiteMonitor classes
• Proper error handling - Try-except blocks with specific exception handling
• Context managers - File operations use with statements
• Type hints - Added for better code clarity
• Logging - Comprehensive logging to file and console
• Clean imports - Removed duplicates and unused imports

Functionality

• Fixed scheduler logic - Removed broken scheduler implementation
• Simplified main loop - Clear, maintainable monitoring loop
• Configurable settings - Environment-based configuration
• Graceful shutdown - Proper cleanup on exit

Setup

Prerequisites

• Python 3.7+
• Chrome/Chromium browser
• ChromeDriver (matching your Chrome version)

Installation

1. Install dependencies:

pip install -r requirements.txt

2. Copy the example environment file:

cp .env.example .env

3. Edit .env and add your credentials:
   • Get a Telegram bot token from @BotFather
   • Get your chat ID by messaging your bot and visiting: https://api.telegram.org/bot<YOUR_BOT_TOKEN>/getUpdates

Configuration

Edit your .env file:

TELEGRAM_BOT_TOKEN=your_bot_token_here
TELEGRAM_CHAT_ID=your_chat_id_here
CHECK_INTERVAL=30  # Check every 30 seconds
SEARCH_STRING=нитЕ  # String to search for

Usage

Run the monitor:

python streamlit_app.py

To load the .env file automatically, you can:

1. Use python-dotenv in the code (add from dotenv import load_dotenv; load_dotenv() at the top)
2. Or export variables manually:

export $(cat .env | xargs)
python streamlit_app.py

How It Works

1. The monitor checks specified URLs at regular intervals
2. It searches for a specific string on each page
3. When the string is found: Registration is likely CLOSED
4. When the string is not found: Registration may be OPEN
5. Telegram alerts are sent for each check result

Logs

• Console output shows real-time monitoring status
• monitor.log file contains detailed logs
• All errors and alerts are logged

Stopping the Monitor

Press Ctrl+C to gracefully stop the monitor. It will clean up temporary files before exiting.

Security Notes

• Never commit your .env file - It contains sensitive credentials
• Keep your Telegram bot token secret
• The .env.example file is safe to commit (contains no real credentials)
