Hepsiburada Price Tracking System

When building this project, my goal was to create an automated system that can track price changes of products on Hepsiburada, one of Turkey’s largest e-commerce platforms. The project:

• ▹ Performs price tracking: It regularly checks prices of products I define.
• ▹ Stores data in a database: Maintains historical price logs in PostgreSQL.
• ▹ Sends Telegram notifications: Sends instant alerts when prices drop or new items are added.
• ▹ Includes a web UI: Provides a React-based frontend for viewing tracked products and price histories.

The setup instructions and dependencies are detailed in the README; the system requires Node.js and database configuration.

Project Story and Challenges

When I started this project, my aim wasn’t just to write a simple price-tracking script. I wanted to build a platform that systematically logs price history, interprets changes, and runs reliably in a production-like environment. Initially, getting consistent results from scraping Hepsiburada pages was challenging. Parsing price data correctly and filtering out malformed or incomplete page data required multiple iterations. I also spent time stabilizing the Telegram bot to ensure reliable, real-time notifications.

Integrating the database and maintaining consistent data flow between the frontend and backend required careful architectural planning. Through this process, I gained clear insights into the practicalities and limitations of scraping-based systems when no paid API is available.
