A desktop system for managing tickets to a basketball tournament. The application provides secure authentication, ticket sales, search, and logout. Connected clients receive live updates about seat availability.
Match administration (CRUD) is handled through a separate Next.js web module.
- Cashier authenticates with username & password (passwords stored using BCrypt).
- On success, the desktop application opens, showing the list of matches.
- Sell tickets by entering customer name, address, and number of seats.
- All active clients instantly see updated seat availability (Observer pattern with gRPC streaming).
- Sold-out matches are marked in red.
- Search tickets by name and/or address.
- If multiple customers share the same name → all tickets are displayed.
- Results include: customer, address, match, and seats.
- Session invalidation.
- Clean disconnection from the server.
- Web module for CRUD operations on matches: teams, stage (semifinal, final), price, capacity, date/time.
