Statiq uses a dependency injection container to provide certain services and you can register your own services and use them in your pipelines and modules.

You can register a service through the bootstrapper using the ConfigureServices extension method which provides an IServiceCollection:

using System;
using Statiq.App;

namespace MyGenerator
{
  public class Program
  {
    public static async Task<int> Main(string[] args) =>
      await Bootstrapper
        .Factory
        .CreateDefault(args)
        .ConfigureServices(services =>
          services.AddTransient<IMyService, MyServiceInstance>())
        .RunAsync();
  }
}

Once a service is registered, you can access it through the Services property of the execution context.

You can also inject dependencies into pipelines.
