Nexus

Nexus is a state-driven service/controller framework for Luau and Roblox, powered by the high-performance Snap networking engine.

Documentation (Diátaxis Standard)

• Tutorial: A step-by-step guide to building your first Service and Controller.
• Recipes: Practical patterns for middleware, state management, and lifecycle events.
• Concepts: Understanding the Service-Controller architecture and the Marker-based networking system.
• Specification: Formal API reference and technical specification.

Technical Highlights

• Marker-Based Protocol: Define signals, methods, and shared properties using a declarative schema.
• Reactive Properties: Built-in state synchronization with Observe and OnChanged hooks.
• Lazy Proxies: Robust dependency injection that solves circular reference issues.
• Advanced Middleware: Inbound and outbound pipelines for granular control over every network packet.
• Unified Lifecycle: Streamlined NexusInit and NexusStart phases with full Promise support.

Minimal Example

-- Service (Server)
local DataService = Nexus.CreateService({
    Name = "DataService",
    Client = {
        Points = Nexus.Property(Nexus.t.uint32, 0)
    }
})

function DataService:NexusStart()
    self.Client.Points:Set(100)
end

-- Controller (Client)
local UIController = Nexus.CreateController({ Name = "UIController" })

function UIController:NexusInit()
    local DataService = Nexus.GetService("DataService")
    DataService.Points:Observe(function(val)
        print("Points updated:", val)
    end)
end

Architected for clarity. Optimized for state.
