WebSocket V2 commands provide a more powerful, event-driven alternative to the basic WebSocket commands. They support long-running connections with hooks for connection, message, error, and close events. Multiple protocol variants are supported: native, SignalR, SignalR-legacy, and Socket.IO.

​
Overview

WebSocket V2 commands provide functionality for:
  • Long-running WebSocket connections with configurable event hooks
  • SignalR, Socket.IO, and native protocol support
  • Decode of SignalR/LZ4/gzip payloads
  • Clean connection teardown

​

Common Use Cases

  • SignalR Feeds: Subscribe to SignalR hubs for live data streams
  • Socket.IO Integration: Connect to Socket.IO servers and subscribe to events
  • Long-Running Connections: Maintain connections that receive many messages over time
  • Heartbeat Patterns: Use onInterval to send periodic heartbeat messages
