Version: v3_socketio_v1.x.x

SocketIO Legacy Event Shim

Compatibility shim for applications that used older socketio releases as a plain WebSocket event bus.

Deprecated: import github.com/gofiber/contrib/v3/websocket/event directly for new code. The root github.com/gofiber/contrib/v3/socketio package is reserved for the Engine.IO / Socket.IO protocol and clients such as socket.io-client.

Migration

Preferred import:

import "github.com/gofiber/contrib/v3/websocket/event"

Temporary compatibility import:

import "github.com/gofiber/contrib/v3/socketio/legacy"

The shim re-exports the old event-bus surface:

legacy.On(legacy.EventMessage, func(ep *legacy.EventPayload) {
	ep.Kws.Emit([]byte("pong"), legacy.TextMessage)
})

app.Get("/ws", legacy.New(func(kws *legacy.Websocket) {}))

Set tuning globals such as PongTimeout, SendQueueSize, or MaxSendRetry on github.com/gofiber/contrib/v3/websocket/event directly before accepting connections.
