WinUIStateBasedViewModel 1.0.4

WinUI 3 Event-State Based ViewModel

This library simplifies the use of ViewModels in WinUI 3 projects, providing easy access to state flows and event handling.

Features

• State Management: Manage state immutably using state flows.
• Event Handling: Handle events effectively with a clear structure.
• Simplified ViewModel: Provides a structured approach to ViewModel implementation in WinUI 3.

Installation

To install the library, add the following NuGet package to your project:

dotnet add package WinUIStateBasedViewModel

Usage

Define Your State

Create a class that extends ViewModelState and define the properties of your state.

using WinUIViewModel.Presentation.State;

public class TestState : ViewModelState
{
    public string Name { get; set; }
    public string Age { get; set; }

    public TestState(string name = null, string age = null)
    {
        Name = name;
        Age = age;
    }
}

Implement Your ViewModel

Create a ViewModel class that extends ViewModel<State, Event, Effect>. Implement the required methods and handle state updates and effects.

using WinUIViewModel.Presentation;
using WinUIViewModel.Presentation.State;

public class MyViewModel : ViewModel<TestState, MyEvent, MyEffect>
{
    public override TestState createInitialState()
    {
        return new TestState { Name = "DefaultName", Age = "DefaultAge" };
    }

    public override void handleEffect(MyEffect effect)
    {
        // Handle effect
    }

    public void UpdateAge(string newAge)
    {
        var newState = currentState.Copy(newValues =>
        {
            newValues.Age = newAge;
        });
        updateState(newState);
    }
}

Handling State and Events

Use the updateState method to update the state immutably. The sendEvent method can be used to handle events.

public void SomeMethod()
{
    // Update the age property of the state
    var newState = currentState.Copy(newValues =>
    {
        newValues.Age = "21";
    });
    updateState(newState);
}
