n8n WebSocket Standalone Nodes

Community node package for n8n (v2.0.9) that provides standalone WebSocket trigger and response nodes, enabling real-time WebSocket server creation without relying on n8n's HTTP server. Supports custom port/path configuration, connection persistence between trigger and response nodes, automatic ping/pong keep-alive, and JSON/plain text messaging. Updated irregularly on GitHub. Differentiator: fully independent WebSocket server mode vs n8n's built-in WebSocket node.
