⚡ Synchronizer

A high-performance state synchronization library for Roblox.

---

Overview

Synchronizer manages server-authoritative data channels with automatic client replication, batched networking, and event-driven updates. Instead of manually firing RemoteEvents, you mutate a channel and Synchronizer handles the rest.

Features

• Channel-Based Architecture — Isolated, reusable data channels per-player, per-entity, or global.
• Batched Networking — All mutations within a frame sent as a single RemoteEvent per listener.
• Action Deduplication — Multiple Set calls to the same path only send the final value.
• Event-Driven — Subscribe to Changed, ArrayInsert, ArrayRemoved, DictionaryInsert, DictionaryRemoved.
• Listener System — Control which players receive updates from each channel.
• Security — Rate limiting and listener-only data access validation.
• Strict Typing — Full --!strict with exported types for IDE autocompletion.
• Zero Memory Leaks — Complete cleanup on channel destruction.

Quick Example

-- Server
local channel = Synchronizer:Create(player.UserId, {
    coins = 0;
    level = 1;
})
channel:AddListener(player)
channel:Set("coins", 100):Increase("coins", 50)

-- Client
local channel = Synchronizer:Wait(player.UserId)
channel:OnChanged("coins", function(new, old)
    print("Coins:", old, "→", new)
end, true)
