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 ?
from contrib.
Thanks a lot @antoniodipinto
This was very helpful!
from contrib.
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
