Remote

A lightweight, type-safe utility module for working with RemoteFunctions and RemoteEvents in Roblox. Simplifies server-client communication with a clean API and full Luau type support.

Installation

Add to your wally.toml:

[dependencies]
Remote = "stackyzdev/remote@0.1.0"

Then run:

wally install

API

local Remote = require(path.to.Remote)

Remote.Function<T..., U...>(name: string, parent: Instance?): Function<T..., U...>

Creates or retrieves a RemoteFunction with the given name.

Remote.Event<T...>(name: string, parent: Instance?): Event<T...>

Creates or retrieves a RemoteEvent with the given name.

Remote.Unreliable<T...>(name: string, parent: Instance?): Event<T...>

Creates or retrieves an UnreliableRemoteEvent with the given name.

If no parent is provided, it defaults to the module's script instance. On the server, instances are created automatically; on the client, the module waits for them to replicate.

Usage

RemoteEvent

local Remote = require(path.to.Remote)

local myEvent = Remote.Event("MyEvent")

-- Server
myEvent.OnServerEvent:Connect(function(player, message)
    print(player.Name, message)
end)

-- Client
myEvent:FireServer("Hello from client!")

RemoteFunction

local Remote = require(path.to.Remote)

local myFunction = Remote.Function("MyFunction")

-- Server
myFunction:OnServerInvoke(function(player, arg1)
    return "Got: " .. tostring(arg1)
end)

-- Client
local result = myFunction:InvokeServer("ping")
print(result) -- "Got: ping"

UnreliableRemoteEvent

local Remote = require(path.to.Remote)

local positionUpdate = Remote.Unreliable("PositionUpdate")

-- Server
positionUpdate:FireAllClients(Vector3.new(0, 10, 0))

Creating a Networking Package

Because every remote is fully typed, you can define all your game's remotes in a single shared module, acting as a central, type-safe networking layer that both server and client scripts import.

-- ReplicatedStorage/Network.luau
local Remote = require(path.to.Remote)

local Network = {
    -- Events
    PlayerDamaged = Remote.Event("PlayerDamaged") :: Remote.Event<number>,
    ChatMessage = Remote.Event("ChatMessage") :: Remote.Event<string, string>,
    ItemPickedUp = Remote.Event("ItemPickedUp") :: Remote.Event<string, number>,
    
    -- Unreliable (high-frequency, loss-tolerant)
    PositionSync = Remote.Unreliable("PositionSync") :: Remote.Event<Vector3, Vector3>,
    
    -- Functions
    GetInventory = Remote.Function("GetInventory") :: Remote.Function<(), { [string]: number }>,
    PurchaseItem = Remote.Function("PurchaseItem") :: Remote.Function<(string, number), boolean>,
}

return Network

Then use it anywhere with full autocomplete and type checking:

-- Server Script
local Network = require(ReplicatedStorage.Network)

Network.PlayerDamaged.OnServerEvent:Connect(function(player, damage)
    -- `player` is Player, `damage` is number ✓
end)

Network.GetInventory:OnServerInvoke(function(player)
    -- must return { [string]: number } ✓
    return { Sword = 1, Shield = 2 }
end)

-- Client Script
local Network = require(ReplicatedStorage.Network)

Network.ChatMessage:FireServer("general", "Hello!")        -- (string, string) ✓
Network.PositionSync.OnClientEvent:Connect(function(pos, vel)
    -- `pos` and `vel` are Vector3 ✓
end)

local inventory = Network.GetInventory:InvokeServer()      -- returns { [string]: number } ✓

This pattern gives you a single source of truth for every remote in your game, with full type safety across the server-client boundary.

Types

The module exports the following types for use in typed Luau code:
