ReactiveUI.Samples

This repository will contain all of ReactiveUI samples.

Xamarin Forms

Cinephile

Example in Xamarin Forms (Android and iOS) shows you the upcoming movies from the movie api

Provides examples about:

App's bootstrapping
ViewModel first routing
ListView integration
ReactiveCommands
ObservableAsPropertyHelper

Xamarin Native

Examples provided:

Reactive Recycler View

Avalonia

To read navigation stack from disk, a suspension driver is required to support deserializing IRoutableViewModel interface implementations into more specific view model types, for Newtonsoft.Json this can be achieved by using TypeNameHandling.All json serialization setting. In the App.OnFrameworkInitializationCompleted method we initialize suspension stuff specific to our app. Don't forget to add .UseReactiveUI() and .StartWithClassicDesktopLifetime() to your app builder inside the Program.cs file.

Provides examples about:

Note: Avalonia produce and support the ReactiveUI plugin. You can get support on their

Testing

ReactiveUI.Samples.Testing.SimpleViewModels

Illustrates how to write testable and maintainable view models using ReactiveUI.Testing, XUnit and Microsoft.Reactive.Testing libraries. See related documentation. Contains immediate scheduling examples to make the tests run even faster by mocking long-running operations.

new TestScheduler().With(scheduler =>
{
    var fixture = new WebCallViewModel(new ImmediateWebService());
    fixture.InputText = "hi";

    // Run the clock forward to 800 ms. 
    // At that point, nothing should have happened.
    scheduler.AdvanceToMs(799);
    Assert.Equal(string.Empty, fixture.ResultText);

    // Run the clock 1 tick past and the result should show up.
    scheduler.AdvanceToMs(801);
    Assert.Equal("result hi", fixture.ResultText);
});

Universal Windows Platform

ReactiveUI.UwpRouting

Provides examples about ReactiveUI routing for Universal Windows Platform.

Razor

ReactiveUI.RazorExample

Building a web app with ReactiveUI and Razor Components.

Follow the Razor Components tutorial on MSDN to get started. Heavily based on @akourbat's work.

More Avalonia samples

Self-contained multiplatform samples to help understanding: ReactiveX, ReactiveUI, Avalonia UI. Featuring links to original reference material for each fresh chunk of code, e.g.

// https://reactiveui.net/docs/handbook/events/#how-do-i-convert-my-own-c-events-into-observables
Observable
    .FromEventPattern(wndMain, nameof(wndMain.Closing))
    .Subscribe(_ => Console.WriteLine("Main window closing..."))
    .DisposeWith(disposables);

Hello World

Uses a finite observable stream of timer ticks. At each tick a new greeting is displayed. The sample can be a template for ReactiveUI + Avalonia applications.

Topics: View, ViewModel, (de)activation, reactive property, type-safe bindings, WhenAnyValue, observable timer, UI thread and schedulers, window event.

Random Buddy Stalker

Shows how to use async/await in a ReactiveUI context. It calls a dummy (but real) RESTful API.

Topics: command binding, ReactiveUI.Fody, Rx event pattern, async/await, timeout, json, Flurl.
