🤗 [Question]: Not sure how the socket.io requests are being handled about contrib

[antoniodipinto]

Any websocket requires a GET route to initiate, that's why @struckchure is getting a 404.
And also there is no socketio.New established

func NewWebsocketModule(app *fiber.App, deploymentHandler handlers.DeploymentHandlerInterface) {
	wsGroup := app.Group("/socket.io/")

	wsGroup.Use(func(c *fiber.Ctx) error {
		// IsWebSocketUpgrade returns true if the client
		// requested upgrade to the WebSocket protocol.
		if websocket.IsWebSocketUpgrade(c) {
			c.Locals("allowed", true)
			return c.Next()
		}
		return fiber.ErrUpgradeRequired
	})

	socketio.On(socketio.EventConnect, func(ep *socketio.EventPayload) {
		fmt.Printf("Connection event 1 - User: %s", ep.Kws.GetStringAttribute("user_id"))
	})
	socketio.On(types.DEPLOYMENT_LOG_STREAM_EVENT, deploymentHandler.StreamMachineDeployment)
	socketio.On(types.DEPLOYMENT_NOTIFICATION_EVENT, deploymentHandler.DeploymentNotification)
	
	
	// =================== socketio.New added for GET request =====================
        wsGroup.Get("/init", socketio.New(func(kws *socketio.Websocket) {
             // handle the connection
             // more examples here https://github.com/gofiber/recipes/blob/master/socketio/main.go
	}))
}

The url is the right one, this library is not meant to be compatible with socketio client. Use a standard javascript implementation to use this. Something like this:

let socket = new WebSocket("ws://127.0.0.1:8000/socket.io/init");

socket.onopen = function(e) {
  alert("[open] Connection established");
  alert("Sending to server");
  socket.send("My name is John");
};

// here you will receive
socket.onmessage = function(event) {
  alert(`[message] Data received from server: ${event.data}`);
};

socket.onclose = function(event) {
  if (event.wasClean) {
    alert(`[close] Connection closed cleanly, code=${event.code} reason=${event.reason}`);
  } else {
    // e.g. server process killed or network down
    // event.code is usually 1006 in this case
    alert('[close] Connection died');
  }
};

socket.onerror = function(error) {
  alert(`[error]`);
};

Send data like this

socket.send({
// the payload you expect to receive in fiber
});

Remember, to fire an event you should use the Fire function from the decoded message object

@antoniodipinto can you help here ?

Thanks a lot @antoniodipinto

This was very helpful!

Thanks @antoniodipinto

To be sure, my connection URL should looks something like this ws://127.0.0.1:8000/socket.io/init?
And also, would I be able to use the socket.io client with it?

I'm testing with postman with the ws client, it works, but it does not work with the socket-io client
