SwapState

The Problem

In SPAs, state management is complex. Redux, Context, Signals—all exist to synchronize client state with server data.

The Solution

The server is the single source of truth. State is serialized into hidden inputs and travels with each request.

1. Define Your State

public class FilterState : SwapState

{

    public string Group { get; set; } = "all";

    public bool ShowCompleted { get; set; } = false;

}

2. Render & Bind

<swap-state state="Model.State" />

public IActionResult Filter([FromSwapState] FilterState state)
