This document demonstrates how to build a simple web application using Nancy and Simple.Data. It shows code samples for basic routing and data access using Simple.Data to query and insert data. It also covers adding authentication to Nancy applications using Nancy.Authentication.Forms to require authentication and redirect unauthorized users. The document proposes an exercise to build a Super-Duper-Happy ToDo application using these libraries with a SQL CE database and encryption helper.

1. Nancy & Simple.Data The Super-Duper-Happy Path

2. Nancy Inspired by Sinatra www.sinatrarb.com Low ceremony High productivity

3. Hello Nancy Demo

4. namespace NancyDemo { public class MainModule : Nancy.NancyModule { public MainModule() { Get["/hi"] = _ => "Hello World!"; } } }

5. Simple.Data Inspired by DataMapper & ActiveRecord datamapper.org rubyonrails.org Dynamic Flexible

6. Hello Simple.Data Demo

7. namespace Hello { classProgram { staticvoid Main() { vardb = Simple.Data.Database.Open(); var hello = db.Hello.FindById(1); Console.WriteLine("{0}, {1}!", hello.Greeting, hello.Subject); } } }

8. Nancy, meetSimple.Data Simple.Data, meet Nancy

9. publicclassMainModule : NancyModule { privatereadonlydynamic _db = Database.OpenNamedConnection("ProgNet"); publicMainModule() { Get["/"] = _ => { var scrawls = _db.Graffiti.All().OrderByAddedDescending(); returnView["index", scrawls]; }; Post["/"] = _ => { _db.Graffiti.Insert(Text: Request.Form.Text); returnnewRedirectResponse("/"); }; } }

10. Authentication Nancy.Authentication.Basic Basic HTTP authentication Nancy.Authentication.Forms Proper authentication Also works as basis for Social login (e.g. Facebook, Twitter)

11. publicclassMyBootstrapper: DefaultNancyBootstrapper { protectedoverridevoidInitialiseInternal(TinyIoC.TinyIoCContainer container) { base.InitialiseInternal(container); FormsAuthentication.Enable( this, newFormsAuthenticationConfiguration { RedirectUrl = "~/login", UsernameMapper = container.Resolve<IUsernameMapper>() }); } } publicclassMyModule: NancyModule { publicMyModule() : base("/secure") { this.RequiresAuthentication(); Get["/"] = _ => "Secure!"; } }
