NexusLabs.Needlr.Hosting

Generic Host support for Needlr - enables auto-discovery and plugin system for worker services and console applications.

Quick Start

Option 1: Needlr Controls the Host

using NexusLabs.Needlr.Hosting;
using NexusLabs.Needlr.Injection;

var host = new Syringe()
    .ForHost()
    .UsingOptions(() => CreateHostOptions.Default
        .UsingArgs(args)
        .UsingApplicationName("MyWorkerService"))
    .BuildHost();

await host.RunAsync();

Option 2: User Controls the Builder

using Microsoft.Extensions.Hosting;
using NexusLabs.Needlr.Hosting;
using NexusLabs.Needlr.Injection;

var builder = Host.CreateApplicationBuilder(args);

// Your own configuration
builder.Services.AddMyServices();

// Add Needlr discovery
builder.UseNeedlrDiscovery();

var host = builder.Build();

// Optionally run IHostPlugin plugins
host.RunHostPlugins();

await host.RunAsync();

Plugin Interfaces

IHostApplicationBuilderPlugin

Runs during builder configuration (before Build()):

public sealed class MyBuilderPlugin : IHostApplicationBuilderPlugin
{
    public void Configure(HostApplicationBuilderPluginOptions options)
    {
        options.Builder.Services.AddSingleton<IMyService, MyService>();
    }
}

IHostPlugin

Runs after Build() but before Run():

public sealed class MyHostPlugin : IHostPlugin
{
    public void Configure(HostPluginOptions options)
    {
        var service = options.Host.Services.GetRequiredService<IMyService>();
        service.Initialize();
    }
}

Key Features

  • ForHost() - Transitions Syringe to host mode, Needlr controls lifecycle
  • UseNeedlrDiscovery() - Integrates discovery into user-controlled builders
  • IHostedService auto-discovery - Background services registered automatically
  • Full parity between reflection and source-gen modes
