This is a socket.io client for Roblox, using the HTTPService.
This allows you to connect to a socket.io server and emit and receive messages.
FEATURES
- Connect to a socket.io server
- Emit messages
- Recive messages
DOWNSIDES
- Does not support socket.io binary data
- Uses all HTTPService requests
- Limited messages every minute (due to HTTP ratelimits)
- Does not currently have support for message acknowledgement (yet)
Tutorial
First, create an instance of the io class:
local io = require(game.ServerStorage.SocketIO) -- Replace the path to where you are storing the module. This returns a function.
local client = io("http://localhost:5000") -- Replace this with your own URL.
You will need a socket.io server, I am using this simple one I made in python:
import socketio
import eventlet
from eventlet import wsgi
sio = socketio.Server()
app = socketio.WSGIApp(sio)
@sio.on("test")
def recv(sid,data):
sio.emit("response",data["data"],room=(sid))
wsgi.server(eventlet.listen(('localhost',5000)),app)
You can listen to events using the :on function:
client:on("response",function(data)
print(data)
end)
And emit events with the :emit function:
client:emit("test",{data="Test Data"})
The finished script looks like:
local io = require(game.ServerStorage.SocketIO) -- Replace the path to where you are storing the module. This returns a function.
local client = io("http://localhost:5000") -- Replace this with the URL to the socket.io server
client:on("response",function(data)
print(data)
end)
client:emit("test",{data="Test Data"})
And if you did every thing right the output should print:
Test Data
If you get HttpError: ConnectFail, that means the server is disconnected.
