What's SwizzleV

What is SwizzleV?​

SwizzleV is a lightweight framework for managing ViewModels and encapsulating component behavior in UI applications. It provides clear patterns for defining whether a ViewModel instance should be unique (transient) or shared (scoped), allowing developers to design components with well-contained logic and lifecycle control.

SwizzleV is not a global state management system.
It focuses on local ViewModel instances, giving developers precise control over behavior without introducing shared application-wide state.

What Makes SwizzleV Different?​

  • Precise Lifetime Control: SwizzleV lets you define ViewModels as either transient (per component instance) or scoped (shared across related components). This prevents unintended reuse or leakage.

  • Framework-Agnostic Design: ViewModels in SwizzleV are not tied to any specific UI framework. They work independently and can be used in Blazor, MAUI, WPF, or any other system that supports C#.

  • Explicit UI Binding via Interface: Instead of automatic change propagation, SwizzleV uses a simple binding contract:
    The consumer (such as a Blazor component) explicitly binds to a ViewModel, implementing an interface that exposes an OnChange() method or similar action.

  • Change Notification via SpreadChanges(): When a ViewModel needs to notify its bound user (UI/s), it calls SpreadChanges(), which invokes the consumer’s provided callback. This enables full decoupling from UI frameworks and provides a clean reactive loop without hardwiring to component lifecycles.

Summary​

SwizzleV is purpose-built for managing component-level behavior and logic through ViewModels. Its framework-agnostic, opt-in change propagation system gives developers a high degree of flexibility, making it ideal for projects that value modularity, clarity, and UI-framework independence
