Setup

Install the extension
Place the following script in your executor's autoexec folder:

local WS_HOST = "ws://localhost:7777"
local RECONNECT_DELAY = 5

local Players = game:GetService("Players")
local player = Players.LocalPlayer
if not player then
    repeat task.wait(0.1) until Players.LocalPlayer
    player = Players.LocalPlayer
end

local function connect()
    local ok, socket = pcall(function()
        return WebSocket.connect(WS_HOST)
    end)

    if not ok then
        task.delay(RECONNECT_DELAY, connect)
        return
    end

    pcall(function()
        socket:Send("__VOLT_USER__:" .. player.Name)
    end)

    socket.OnMessage:Connect(function(script)
        local fn, _ = loadstring(script)
        if not fn then return end
        pcall(fn)
    end)

    socket.OnClose:Connect(function()
        task.delay(RECONNECT_DELAY, connect)
    end)
end

connect()
