Socket.IO Godot Client

This is a Socket.IO and Engine.IO client addon for Godot written in GDScript that supports both HTTP long-polling and Websocket.

This is still a work in progress and is not yet fully featured. Please make sure to check out the #features section before using it. The current implementation is functional and works, but there are some known cases that have not been implemented or covered yet (like binary messages)

Compatibility

I haven’t checked the current implementation with older versions of the Godot and Socket.IO server. I hereby ask you to do this and inform me if it works or not.

Quickstart

Add the Socket.IO node to your tree and fill out the parameters in the Inspector, connect the signals via code or IDE, and use it.

@onready var client: SocketIO = $SocketIO

func _ready() -> void:
    client.socket_connected.connect(_on_socket_connected)
    client.event_received.connect(_on_event_received)

func _on_connect_pressed() -> void:
    client.make_connection()

func func _on_socket_connected() -> void:
    client.emit("hello")
    client.emit("some_event", { "value": 10 })

func _on_event_received(event: String, data: Variant, ns: String) -> void:
    print("event %s with %s as data received" % [event, data])
