socketio

socketio parses event-style Socket.IO text packets without forcing Socket.IO into the WebSocket transport itself.

That design is intentional:

• wsproxy stays reusable for all WebSocket traffic
• Socket.IO decoding remains optional
• higher-level protocol interpretation happens in your adapter layer

Main entry point

namespace, event, argsJSON, ok := socketio.ParseEvent(packet)

What it supports

ParseEvent understands common Socket.IO v3 and v4 event-like text packet forms:

• 42 event packets
• 45 binary event packets
• 43 ack packets
• 46 binary ack packets

Example

namespace, event, argsJSON, ok := socketio.ParseEvent(`42/chat,17["message",{"body":"hello"}]`)

Typical result:

• namespace: /chat
• event: message
• argsJSON: raw JSON array payload

Why raw JSON output is useful

The package returns the event payload as JSON text instead of binding it to a fixed struct.

That keeps the package:

• lightweight
• schema-agnostic
• useful for debuggers, inspectors, and custom adapters
