Questions about rebuilding Booking.com price tracker
How does the extension capture price history?
A content script reads the room type, dates, and price from the Booking.com DOM whenever you visit a hotel page, saving the data with a timestamp to your local storage or Supabase.
How is the price history chart rendered on the page?
The content script injects a floating container or modifies the hotel pricing section, using a lightweight charting library like Chart.js to plot previous prices.
Can it alert me when a price drops?
Yes. You can store your target price thresholds and have the extension trigger native browser notifications or trigger a Supabase Edge Function to email you.
