WebSocket
Establish persistent WebSocket connections for real-time bidirectional messaging between a Roblox executor script and a remote endpoint.
A persistent, two-way connection to a server of your own. Where request is one shot, a WebSocket stays open, which is what you want for a remote control panel, a live logger, or anything that has to push to you rather than be polled.
A full session
local socket = WebSocket.connect("ws://localhost:8080")
socket.OnMessage:Connect(function(message)
print("server said:", message)
end)
socket.OnClose:Connect(function()
warn("connection closed")
end)
socket:Send("hello")
-- ... later
if not socket.IsClosed then
socket:Close()
endGuard the send
Sending on a closed socket errors. Check IsClosed, and treat OnClose as the signal to stop rather than as a notification.
OnMessage and OnClose are typed Signal instances; connect to them with :Connect(callback). They share the same surface as BindableEvent.Event, so any pattern you would use with a BindableEvent works here too.
