A bootstrapper implementation, for the Nancy framework, based on the Autofac inversion of control container.

Usage

When Nancy detects that the AutofacNancyBootstrapper type is available in the AppDomain of your application, it will assume you want to use it, rather than the default one.

The easiest way to get the latest version of AutofacNancyBootstrapper into your application is to install the Nancy.Bootstrappers.Autofac nuget.

public interface ISmtpService { }

public class SmtpService : ISmtpService { }

public class Bootstrapper : AutofacNancyBootstrapper
{
    protected override void ConfigureApplicationContainer(ILifetimeScope container)
    {
        container.Update(builder => builder.RegisterType<SmtpService>().As<ISmtpService>().SingleInstance());        
    }
}

Customizing

By inheriting from AutofacNancyBootstrapper you will gain access to the ILifetimeScope of the application and request containers and can perform what ever registrations that your application requires.

public class Bootstrapper : AutofacNancyBootstrapper
{
    protected override void ApplicationStartup(ILifetimeScope container, IPipelines pipelines)
    {
        // No registrations should be performed in here, however you may
        // resolve things that are needed during application startup.
    }

    protected override void ConfigureApplicationContainer(ILifetimeScope existingContainer)
    {
        // Perform registration that should have an application lifetime
    }

    protected override void ConfigureRequestContainer(ILifetimeScope container, NancyContext context)
    {
        // Perform registrations that should have a request lifetime
    }

    protected override void RequestStartup(ILifetimeScope container, IPipelines pipelines, NancyContext context)
    {
        // No registrations should be performed in here, however you may
        // resolve things that are needed during request startup.
    }
}

Using container builder for registrations is simple.

container.Update(builder => builder.RegisterType<MyImplementation>().As<MyInterface>());

You can also override the GetApplicationContainer method and return a pre-existing container instance, instead of having Nancy create one for you. This is useful if Nancy is co-existing with another application and you want them to share a single container.

protected override ILifetimeScope GetApplicationContainer()
{
    // Return application container instance
}
