How yourswaroop/bookzs-backend works

Bookzs is a backend API for a book marketplace, supporting user accounts, book and listing management, sales, exchanges, and messaging. Users enter through the Express app; authenticated routes pass requests to domain controllers, which invoke services and, in sampled flows, query modules. The server also initializes Socket.IO. The tree and excerpts establish the major domains, but most route, service, and query implementations were not sampled, so their internal wiring is left unspecified.
