JavaScript Filename Extractor

This project provides a Python script for extracting and saving filenames of JavaScript files (index.js) from a given webpage. It leverages the requests library for making HTTP requests and loguru for enhanced logging.

---

Features

• URL Validation: Ensures the provided base URL is valid.
• Retry Mechanism: Automatically retries failed HTTP requests.
• JavaScript Filename Extraction: Uses regular expressions to locate JavaScript files in the HTML source of a webpage.
• Storage Support: Saves extracted filenames to a specified file.
• Customizable Base URL and Output File: The script allows configuring the base URL and output file path.

Prerequisites

Ensure the following Python packages are installed:

• requests
• loguru

Install them via pip:

pip install requests loguru

Usage

1. Clone this repository:

git clone https://github.com/Enukio/Update-Index.git

cd Update-Index

2. Edit the script to set the correct BASE_URL and OUTPUT_FILE in the Index.py file:

BASE_URL = "https://example.com"  # Replace with your target URL
OUTPUT_FILE = "./cgi"  # File where filenames will be saved

3. Run the script:

python Index.py

4. Output files will be saved to the specified OUTPUT_FILE path.

Example Output

When run with a valid URL containing JavaScript files, the script will find <script> tags with src attributes like:

<script src="/assets/index-abc123.js"></script>

The resulting list will include:

index-abc123.js

---

Logging

The script outputs detailed logs with colored formatting, including:

• The number of JavaScript files found.
• Success or error messages for file-saving operations.
• Issues with fetching the webpage or unexpected content types.

Limitations

• Assumes JavaScript filenames match the pattern /index*.js.
• Designed for basic extraction and may require adjustments for complex or dynamically loaded webpages.
