How to document a Socket.IO API?
summary
Claims that the Socket.IO protocol maps cleanly to AsyncAPI, demonstrates a full YAML spec for a 90-line minimal chat server, and proposes an x-act acknowledgement extension to model Socket.IO acks. Uses AsyncAPI channels for namespaces, websocket bindings for handshake query params, JSON Schema for payloads, and the AsyncAPI playground for visualization. Ships Asynction, a Python framework (Flask‑SocketIO) that auto-registers handlers, validates traffic, generates docs and runs a mock server via CLI — it works end to end.
