I integrated Twitter posting into the scraper using the Tweetinvi library. Now when the scraper finds sale products, it automatically tweets one with the product image, discount percentage, original price, sale price, and a link to buy.

I also refactored the application to use .NET’s generic host pattern with dependency injection and configuration from user secrets. This cleaned up the main entry point considerably and moved the Chrome driver setup and product fetching into dedicated methods. The configuration now pulls Twitter API credentials and connection strings from environment variables or user secrets rather than command line arguments.
