Development Builds

Development builds are available on the feedz.io feed. A development build is promoted to the main NuGet feed when it's determined to be stable.

In your Package Manager settings add the following package source for development builds: https://f.feedz.io/loresoft/open/nuget/index.json

Features

• Run tasks on application start-up
• Extension model to add library specific start up tasks
• Common IoC container adaptor based on IServiceProvider
• Singleton instance of an application level IoC container Kick.ServiceProvider

Example

This example will scan the assembly containing UserModule. Then it will find all Autofac modules and register them with Autofac. Then, all AutoMapper profiles will be registered with Automapper. Finally, it will find all classes that implement IStartupTask and run it.

Kick.Start(config => config
    .IncludeAssemblyFor<UserModule>()
    .UseAutofac()
    .UseAutoMapper()
    .UseStartupTask()
);

Pass data to the startup modules

Kick.Start(config => config
    .Data("environment", "debug")
    .Data(d =>
    {
        d["key"] = 123;
        d["server"] = "master";
    })
);

Extensions

• StartupTask - Run any class that implements IStartupTask
• Autofac - Registers all Autofac Module classes and creates the container
• AutoMapper - Registers all AutoMapper Profile classes
• DependencyInjection - Register all IDependencyInjectionRegistration instances for Microsoft.Extensions.DependencyInjection
• MongoDB - Registers all BsonClassMap classes with MongoDB serialization

• SimpleInjector - Run all ISimpleInjectorRegistration instances allowing container registration
• Unity - Run all IUnityRegistration instances allowing container registration

StartupTask

The StartupTask extension allows running code on application start-up. To use this extension, implement the IStartupTask interface. Use the Priority property to control the order of execution.

Basic usage

Kick.Start(config => config
    .IncludeAssemblyFor<UserModule>() // where to look for tasks
    .UseStartupTask() // include startup tasks in the Kick Start
);

Run a delegate on startup

Kick.Start(config => config
    .IncludeAssemblyFor<UserModule>()
    .UseAutofac() // init Autofac or any other IoC as container
    .UseStartupTask(c => c =>
    {
        c.Run((services, data) =>
        {
            //do work here
        });
    })
);

Autofac

The Autofac extension allows registration of types to be resolved. The extension also creates a default container and sets it to the Kick.Container singleton for access later.

Basic usage

Kick.Start(config => config
    .IncludeAssemblyFor<UserRepository>() // where to look for tasks
    .UseAutofac() // initialize Autofac
);

Use with ASP.NET MVC

Kick.Start(c => c
    .IncludeAssemblyFor<UserModule>()
    .UseAutofac(a => a
        .Initialize(b => b.RegisterControllers(typeof(MvcApplication).Assembly)) // register all controllers 
        .Container(r => DependencyResolver.SetResolver(new AutofacDependencyResolver(r))) // set asp.net resolver
    )
    .UseAutoMapper()
    .UseMongoDB()
    .UseStartupTask()
);

To install Autofac extension, run the following command in the Package Manager Console

PM> Install-Package KickStart.Autofac

DependencyInjection

The DependencyInjection extension allows using Microsoft.Extensions.DependencyInjection for depenancy injection.

Basic Usage

Kick.Start(config => config
    .LogTo(_output.WriteLine)
    .IncludeAssemblyFor<UserRepository>() // where to look
    .UseDependencyInjection() // initialize DependencyInjection
);

Integrate with asp.net core 2.0

public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        // this will auto register logging and run the DependencyInjection startup
        services.KickStart(c => c
            .IncludeAssemblyFor<UserRepository>() // where to look
            .Data("configuration", Configuration) // pass configuration to all startup modules
            .Data("hostProcess", "web") // used for conditional registration
            .UseStartupTask() // run startup task
        );
    }
}

To install DependencyInjection extension, run the following command in the Package Manager Console

PM> Install-Package KickStart.DependencyInjection

SimpleInjector

The SimpleInjector extension allows registration of types to be resolved by running all instances of ISimpleInjectorRegistration. The extension also creates a default container and sets it to the Kick.Container singleton for access later.

Basic usage

Kick.Start(config => config
    .IncludeAssemblyFor<UserRepository>() // where to look
    .UseSimpleInjector () // initialize SimpleInjector
);

Using SimpleInjector with ASP.NET WebAPI

Kick.Start(c => c
    .LogTo(_logger.Debug)
    .IncludeAssemblyFor<UserModule>()
    .Data("hostProcess", "web")
    .UseSimpleInjector(s => s
        .Verify(VerificationOption.VerifyOnly)
        .Initialize(container =>
        {
            container.Options.DefaultScopedLifestyle = new WebApiRequestLifestyle();
            container.RegisterWebApiControllers(httpConfiguration); // register all controllers
        })
        .Container(container =>
        {
            httpConfiguration.DependencyResolver = new SimpleInjectorWebApiDependencyResolver(container); // set asp.net resolver
        })
    )
    .UseStartupTask()
);

To install SimpleInjector extension, run the following command in the Package Manager Console

PM> Install-Package KickStart.SimpleInjector

Unity

The Unity extension allows registration of types to be resolved by running all instances of IUnityRegistration. The extension also creates a default container and sets it to the Kick.Container singleton for access later.

Basic usage

Kick.Start(config => config
    .IncludeAssemblyFor<UserRepository>() // where to look
    .UseUnity () // initialize Unity
);

To install Unity extension, run the following command in the Package Manager Console

PM> Install-Package KickStart.Unity

xUnit

Example of bootstraping and logging with xUnit tests.

public class StartupTaskStarterTest
{
    private readonly ITestOutputHelper _output;

    public StartupTaskStarterTest(ITestOutputHelper output)
    {
        _output = output;

        // bootstrap project
        Kick.Start(config => config
            .LogTo(_output.WriteLine)
            .Data("environment", "test") // pass data for conditional registration
            .IncludeAssemblyFor<UserRepository>()
            .UseSimpleInjector () // initialize SimpleInjector
            .UseStartupTask()
        );

    }

    [Fact]
    public void RunTest()
    {
        var userRepository = Kick.ServiceProvider.GetService<IUserRepository>();
        Assert.NotNull(userRepository);

        // more tests
    }
}

Generic Service Registration

KickStart has a generic service registration abstraction. This allows for the creation of a generic class module that registers services for dependency injection that is container agnostic.

Example module to register services

public class UserServiceModule : IServiceModule
{
    public void Register(IServiceRegistration services, IDictionary<string, object> data)
    {
        services.RegisterSingleton<IConnection, SampleConnection>();
        services.RegisterTransient<IUserService, UserService>(c => new UserService(c.GetService<IConnection>()));

        // register all types that are assignable to IService
        services.RegisterSingleton(r => r
            .Types(t => t.AssignableTo<IService>())
            .As(s => s.Self().ImplementedInterfaces())
        );

        // register all types that are assignable to IVehicle
        services.RegisterSingleton(r => r
            .Types(t => t.AssignableTo<IVehicle>())
            .As(s => s.Self().ImplementedInterfaces())
        );
    }
}
