Why use Nancy?

Agenda

LightweightWrite less

Sensible defaults

No non sense

DynamicBest effort – very best

Readable!!!!

Testable!!!!

Domain Model

Data access

Accounting

Inventory

Fully composable

Dependency Injection

Easy to isolate

Runs anywhereWindows

» IIS» Windows Service» .exe

Linux + Mono

» ASP.NET» Kayak» executables

Hello World

Where your Nancy experience starts

Organizes your routes

NancyModule

public class MainModule : NancyModule { public MainModule() { Get["/"] = _ => "Hello from root"; } } public class SubModule : NancyModule { public SubModule() : base("subpath") { Get["/"] = _ => "Hello from subpath"; } }

Defines which verbs you accepts

NancyModule

public class MainModule : NancyModule { public MainModule() { Get["/"] = _ => "Hello from root"; Post["/”] = _ => DoPost(Request.Form.my_value) Delete["/{id}”] = p => Delete(p.id); Put["/”] = _ => … Patch["/”] = _ => DoPut(Request.my_data) } }

Allows to setup before and after

NancyModule

public class MainModule : NancyModule { public MainModule() { Before += context => ... ; After += context => ... ; } }

Nancy.Hosting

Your Application

Nancy.Hosting

Usage:> Install-Package Nancy.Hosting.*

Hosts:ASP.NET

Nancy.Hosting

Install: > Install-Package Nancy.Viewengines.*

View engines: Razor

NDjango

DotLiquid

Out-of-the-box: Super Simple View Engine

Nancy.Viewengines

public class MainModule : NancyModule { public MainModule() { Get["/"] = _ => View[”home.cshtml”]; Get["/sayhello"] = _ => View[”say”, ”hello”]; } }

Nancy.Viewengines

INancyBootstrapper

2 methods

DefaultNancyBootstrapper

18 overrideables

Container configuration

Pipeline setup

Override Nancy defaults

NuGets for 5 IoC/DI containers

Nancy.Bootstrapper

public class Bootstrapper : DefaultNancyBootstrapper{ protected override void ApplicationStartup(TinyIoC.TinyIoCContainer container, IPipelines pipelines) { base.ApplicationStartup(container, pipelines); pipelines.BeforeRequest += context => context .Request.Headers .AcceptLanguage .Contains("Danish") ? null : "Only Danish";

pipelines.AfterRequest += context => AddToCache(context.Request.Path, context.Response.Contents); }}

Nancy.Bootstrapper

Usage:> Install-Package Nancy.Authentication.*

Authentication types:Basic

public class SecureModule : NancyModule{ public SecureModule() : base("/secure”) { this.RequiresAuthentication(); Get["/"] = x => View["secure.cshtml”]; } }

public class FormsAuthBootstrapper : DefaultNancyBootstrapper{ protected override void RequestStartup( TinyIoCContainer requestContainer, IPipelines pipelines, NancyContext context) { var formsAuthConf = new FormsAuthenticationConfiguration() { RedirectUrl = "~/login”, UserMapper = requestContainer.Resolve<IUserMapper>() };

FormsAuthentication.Enable(pipelines, formsAuthConf); }}

Will be demoed later …

Nancy.Testing

NancyModule

Nancy.Hosting

Nancy.ViewEngines

Nancy.Bootstrapper

Nancy.Testing

…And we’re only at v 0.9

Close to http

Very, very readable code

Very explicit routing

Embraces modularity

Embraces IoC/DI

Embraces testing

Embraces JSON

Runs anywhere
