How wansky05/baileys works

Baileys is a TypeScript WebSocket client library for WhatsApp Web. An application supplies authentication and socket configuration to makeWASocket; layered socket modules connect to WhatsApp, exchange binary protocol frames, and expose messaging, chat, group, community, business, and newsletter operations. Incoming traffic is decoded and dispatched as events, while Signal-based encryption and authentication state support secure sessions. The tree documents media, history synchronization, calls, and USync capabilities as well. Only selected source files were sampled, so the graph omits uncertain internal call wiring and shows documented capabilities at their enclosing directories.
