JavaScript File Monitor with Telegram Notifications

This Python script monitors JavaScript files or HTML pages for changes and sends updates to a Telegram chat. It can detect new or removed JavaScript files from URLs and send a log of the changes to Telegram.

Features

• Monitors JavaScript files in URLs for changes.
• Sends notifications about added or removed JavaScript files via Telegram.
• Periodically checks for updates based on a configurable interval.
• Supports both file and URL monitoring.
• Sends logs to Telegram with details of the changes.

Requirements

• Python 3.8+
• External Libraries:
  • requests
  • python-dotenv
  • argparse

Install dependencies via pip:

pip install requests python-dotenv

Setup

1. Telegram Setup: You will need a Telegram bot and a chat ID to receive the messages.

   • Create a new Telegram bot via BotFather.
   • Get your Telegram chat ID. (You can find this by using a bot like @userinfobot to get your chat ID.)

2. Environment Variables: Create a .env file in the project directory and add your bot credentials:

   TELEGRAM_BOT_TOKEN=<your_telegram_bot_token>
   TELEGRAM_CHAT_ID=<your_telegram_chat_id>

Usage

1. Configuration File: Create a configuration file (e.g., config.txt) to list the URLs or files you want to monitor. Each item should be listed on a new line:

   Example config.txt:

   https://example.com
   https://example.com/page.html
   

2. Run the Script: You can run the script with the following command:

   python changes.py -c config.txt -t 60 --jjs

   Arguments:

   • -c or --config: The path to the configuration file.
   • -t or --interval: Time interval (in seconds) between checks (default: 60).
   • --jjs: If set, the script will extract and monitor JavaScript files in the HTML content of the URLs.

How It Works

1. Extract JavaScript Files: If the --jjs flag is used, the script extracts JavaScript files from the HTML content of the provided URLs.

2. Monitor for Changes: The script monitors for changes by comparing the previously fetched JavaScript files with the new ones. It detects additions and removals.

3. Telegram Notifications: When a change is detected, the script generates a log and sends it to your Telegram chat as a document.

4. Log File: The log file is generated dynamically, showing the changes with timestamps.

Example

For example, if a new JavaScript file is added or an existing one is removed, the log will look like this:

2025-01-11 12:00:00 https://example.com
[+] line 10: /scripts/new_file.js
[-] line 15: /scripts/old_file.js

[!] Finished

The log will be sent as a document to your Telegram chat.
