Socket.IO Protocol

Bowire connects to Socket.IO 4.x servers, discovers events during a short listen window, and provides emit (unary) and listen (streaming) methods.

Setup

dotnet add package Kuestenlogik.Bowire.Protocol.SocketIo

Standalone

bowire --url http://localhost:3000

Discovery

On connect, Bowire listens for 2 seconds and collects every event name received. These become specific listen methods. Two generic methods are always available:

• emit (Unary) -- send an event with a JSON payload
• listen (ServerStreaming) -- subscribe to all or specific events

Emit Input

{
  "event": "message",
  "data": { "text": "hello" }
}

Listen Output

Each received event is streamed as:

{
  "event": "temperature",
  "data": "{ \"value\": 22.5 }",
  "timestamp": "2026-04-10T12:00:00Z"
}
