`/parties/{party}/{room}`

Name: /parties/{party}/{room}
Creator: PartyKit

A PartyKit room channel. The `party` segment identifies which Party class to route to (defaults to `main`), and the `room` segment is the room id. The PartyKit runtime guarantees that every connection using the same `room` id is routed to the same Durable Object instance, so a room represents a single, isolated, stateful server. Clients open a WebSocket against this path; the server invokes `onCon

About AsyncAPI

The AsyncAPI specification describes event-driven APIs the way OpenAPI describes request/response APIs. A channel is the named pipe — a webhook URL, a Kafka topic, a WebSocket route, an MQTT subject — that producers and consumers publish or subscribe to. Each channel carries one or more messages with structured payloads, and an operation declares whether a given party sends or receives on that channel.
