SpawnDev.BackgroundServices

NuGet

Add support for auto-starting background services based on the running scope. Register services that start automatically in specific contexts - browser windows, web workers, desktop/server, or all of the above.

Getting Started

Add the NuGet package:

dotnet add package SpawnDev.BackgroundServices

Setup

using SpawnDev.BackgroundServices;

var builder = WebAssemblyHostBuilder.CreateDefault(args);

// Add the background service manager
builder.Services.AddBackgroundServiceManager();

// Register services that auto-start in ALL scopes
builder.Services.AddSingleton<IBackgroundService, MyService>();

// Register services that only auto-start in specific scopes
builder.Services.AddSingleton<IBackgroundService, MyWindowService>(GlobalScope.Window);
builder.Services.AddSingleton<IBackgroundService, MyWorkerService>(GlobalScope.AllWorkers);
builder.Services.AddSingleton<IBackgroundService, MyDesktopService>(GlobalScope.NonBrowser);

// Start all background services for the current scope
await builder.Build().Services.StartBackgroundServices();

Interfaces

IBackgroundService

Marker interface. Services implementing this are auto-started when StartBackgroundServices() is called, filtered by the registered GlobalScope.

public class MyService : IBackgroundService
{
    public MyService(ILogger<MyService> logger)
    {
        logger.LogInformation("MyService started");
    }
}

IAsyncBackgroundService

Extends IBackgroundService with a Task Ready property. The background service manager awaits Ready during startup, ensuring the service is fully initialized before other services that depend on it start.

public class MyAsyncService : IAsyncBackgroundService
{
    public Task Ready { get; }

    public MyAsyncService()
    {
        Ready = InitAsync();
    }

    private async Task InitAsync()
    {
        // async initialization
        await Task.Delay(100);
    }
}

IAsyncService

Interface with a Task Ready property. When resolved via GetServiceAsync<T>(), the container awaits Ready before returning the service.

GlobalScope

Flags enum controlling which scopes a service auto-starts in:

Value Description
Window Browser window
DedicatedWorker Dedicated web worker
SharedWorker Shared web worker
ServiceWorker Service worker
NonBrowser Desktop/server (.NET)
AllWorkers All worker types combined
AllBrowser Window + all workers
All Every scope
None Never auto-start
