nostr-websocket-utils/dist/browser/nostr-websocket-utils.min.js

Robust WebSocket utilities for Nostr applications with automatic reconnection, supporting both ESM and CommonJS. Features channel-based messaging, heartbeat monitoring, message queueing, and comprehensive error handling with type-safe handlers.
