Overview

Provides one single source of updating and retrieving data throughout entire application

Requirements

BlazorFocused or BlazorFocused.Store NuGet Package

Quick Start

WebAssembly Blazor Startup

public static async Task Main(string[] args)
{
    var builder = WebAssemblyHostBuilder.CreateDefault(args);
    builder.RootComponents.Add<App>("#app");

    builder.Services.AddScoped(sp =>
        new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });

    builder.Services.AddStore<TestStore>(new TestStore { FieldOne = "Initialized" })
        .AddTransient<TestAction>()
        .AddTransient<TestActionAsync>()
        .AddTransient<TestReducer>()
        .AddScoped<TestService>()
        .AddSingleton<TestSingletonService>();
    await builder.Build().RunAsync();
}

Server-side Blazor Startup

public void ConfigureServices(IServiceCollection services)
{
    services.AddControllersWithViews();
    services.AddRazorPages();

    services.AddStore<TestStore>(new TestStore { FieldOne = "Initialized" })
        .AddTransient<TestAction>()
        .AddTransient<TestActionAsync>()
        .AddTransient<TestReducer>()
        .AddScoped<TestService>()
        .AddSingleton<TestSingletonService>();
}

State

Retrieve static state value from store:

@inject IStore<TestStore> store;
...
store.GetState().FieldOne;

Retrieve state value and subscribe to store updates:

@inject IStore<TestStore> store;
...
TestStore currentState = default;
store.Subscribe((newState) => {
    // update state used in page
    currentState = newState;
    // inform blazor page to refresh with state update
    StateHasChanged();
});

Reducers

Subscribe to reduced value from store:

@inject IStore<TestStore> store;
...
TestStoreSubset subsetState = default;
store.Reduce<TestReducer, TestStoreSubset>(reducedState =>
{
    // helpful if you do not care about the full state in your component
    subsetState = reducedState;
    // inform blazor page to refresh with state update
    StateHasChanged();
});

Actions

Execute actions to update store:

@inject IStore<TestStore> store;
...
TestStore currentState = default;
// call action to be committed
// if action updates state, component will update
store.Dispatch<TestAction>();
store.Subscribe((newState) => {
    // update state used in page
    currentState = newState;
    // inform blazor page to refresh with state update
    StateHasChanged();
});
