Open Event SDK

Open Event SDK for Node.js (v1.0.1) enables WebSocket-based event subscription for open platforms, primarily targeting WPS KSO ecosystem. It supports automatic reconnection with exponential backoff, KSO-1 signature authentication, and two event handling modes: single handler and dispatcher with per-event-code registration. Ships TypeScript definitions with typed event handlers for common events. Requires Node.js >=18. Compared to alternatives, it provides a typed, configurable WebSocket client with built-in reconnection and signature auth.
