Digging deeper into ServiceStackThere is more than just easy webservices

All the boring stuff you will forget after the slides have passedWho, where, what?

Why am I here…• Stefan Daugaard Poulsen• @cyberzeddk• AP in Computer Science• Developer/Architect at Atea Denmark• Currently working on Atea Tele

• .NET developer since 2002• Silverlight developer back in 2011 with high use of

WCF• “Caught” in a discussion about webservices in

November 2011• Got annoyed by RPC style, code-gen webservices

Is it needed? Does it solve anything?

Why is ServiceStack interresting?

What are bad ideas for webservices• Code-gen• It fails…too often

• Archaic Xml configuration• Distribution, misspelling…or even horrible merges

• Defaults that is bound to make you cry• Why do I need to set values that should be default!

• Fixed serialization• Could be nice to talk to more systems no matter who they are

• RPC style services• Maintenance hell

• Chatty services• Bulk it!

What is this ServiceStack thing• Official subtitle:• Web Services done right, REST services done easy :)

• Simple and model-driven• Endpoint ignorant• Authentication built-in• IoC based• Easy access to HTTP• Fast as lightning• Cross platform• Extendable• Oh!... And clients are in the box

This is where the most wheels are turning in your developmentSeen from the serverside

Gentlemen, start your engines…• IService• Service• And a lot more…

Quick steps• Conventionbased registrations• Throw exceptions and have magic

httpstatuscodes• Strong typed returns• It’s more than CRUD• PATCH etc.

• Restrict access to your services

Endpoint ignorant• JSON• Xml• JSV• CSV• SOAP• 1.1• 1.2

• Custom

What was lost in the ”war”• Funq• OrmLite• ICacheClient• MiniProfiler• Validation• Custom responses• Headers

Funq – it’s almost to easy• It’s dead simple• Fullfills the basic needs• It’s fast• If you don’t like …add an adaptor

OrmLite – why stick to EF or Nhibernate?• Do you really need EF?• Do you trust your developers to know SQL?• Want to get closer to the server?• Pragmatic over academic

Caching – we need more problems?• You added caching so now you have more

problems• Cachekey generation• It’s so darn hard!!!

Profiling – it’s so darn easy• Estimates and guesses leaves you nowhere• Easy to give response to the average Joe• Thank you mr. Saffron and Dixon• Don’t reinvent the wheel!!!

Validation – what everyone hates to repeat• if( request.Id != default(int) )• It’s getting boring!

• Leverage the same validation in several places• Fine grain it where needed

Customized responses• If you want another content type• If you need to return an image• If you want to be a joker?

Custom headers – this is a hard one...NOT!!!• CORS• Please don’t use AddHeader

• If you want to you can do it• Location• …Link?• Not sure you want to go that way ;)

…unless you want to go all JS on me :)Welcome to the clientside

Clients• Client interfaces• IServiceClient• IRestClient• IRestClientAsync

• Implementations• Soap11ServiceClient (only for IServiceClient)• Soap12ServiceClient (only for IServiceClient)• JsonServiceClient(Async)• JsvServiceClient(Async)• XmlServiceClient(Async)

• Or you can hookup to the XSDs or WSDLs as well• Might be handy when delivering services to external partners

If you order now you will get … for only $19.99But that’s not all kids…

It’s a freaking swiss army knife!!!• OrmLite• MySQL• PostgreSQL• Sqlite 32 & Sqlite 64• Firebird• Oracle

• Authentication• MongoDB• Nhibernate• OpenId• RavenDB

• Razor

• Caching• Memcached• Azure

• Protobuf• MessagePack• Logging• NLog• Log4Net• ELMAH• Eventlog

• Swagger

Show off time…Grab your whiskies and smile

I’m in the need for speed!• Fastest JSON serializer• Burning Monk JSON Benchmarks (19/11/2012)

Crossplatform• Supports ASP.NET and HttpListener hosts• Runs on Windows with .NET 3.5 and 4.0• IIS 5/6/7 (uses IHttpHandler)• VS.NET WebDev Server (Cassini)• IIS Express• Console App, Windows Gui, Windows Service

• Linux/OSX with Mono• Apache + mod_mono• Nginx + MonoFastCGI• XSP• Console App

• A demo have been done inside iOS with MonoTouch

Hosting – it can be cheap or really expensive!

Hetzner• 2.67 GHZ• 2GB RAM• 80GB HDD• 4TB Traffic

• €19.90• €238.80

Windows Azure• 1.67 GHZ• 1.75GB RAM• 100GB HDD• 2TB Traffic

• €219.50• €2634

Where do we go next?Well where I am going I don’t need roads!!!
