##About

A robust, easy to use, strongly typed, end-to-end StackOverflow API Client Library.

Out of the box, Soapi provides you with a robust client library that abstracts away most all of the messy details of consuming the API and lets you concentrate on implementing your ideas.

A few features include:

• Full coverage of the API, all routes and all parameters.

• Strongly typed Domain Data Objects for all API data structures.

• Eager and Lazy Loading objects. Currently the Soapi workflow involves creating a RouteMap the corresponds to a specific API route and fetching results.

  As an example, when you query for questions, there is a skeleton User object provided that contains just the most relevant fields. Suppose you would like to get the full User object for the owner of a question and then in turn get some of his other good answers....

    var aSmartGuy = thisQuestion.AcceptedAnswer.Owner;
    \\ other answers by aSmartGuy
    aSmartGuy.Answers(sort:PostSort.Votes)
     .ForEach(a=>Console.WriteLine(a.Title));
  

  Now think about how many API requests are required to accomplish this and how nice it will be to just get the data and not worry about building routes.

  Lazy loading may be disabled.

• When finer grained control of requests is desired, the core RouteMap objects may be leveraged to request data from any of the API paths using all available parameters as documented on the help pages.

• A rich Asynchronous implementation.

• A configurable request cache to reduce unnecessary network traffic and to simplify your usage logic. There is no need to go out of your way to be frugal.

  The RequestCache caches all requests for a minimum of 60 seconds, by default. This value is adjustable. You may also set a distinct cache duration for any particular route.

  e.g. You typically need to get the list of sites from stackauth every few hours.

  RequestCache.SetDuration(typeof(SitesRouteMap), new TimeSpan(2,0,0));

• A configurable request throttle to ensure compliance with the api terms of usage and to simplify your code in that you do not have to worry about and respond to 503 errors.

  By default, the throttle is set to maintain a minimum interval of 170ms (.17 seconds) between requests. If you would like to manage your requests manually simply set the throttle to 0.

  The RequestCache and Throttled Queue are thread-safe, so can make as many requests as you like from as many threads as you like as fast as you like and not worry about abusing the api or having to write reams of management/compensation code.

• Configurable retry threshold that will, by default, make up to 3 attempts to retrieve a request before failing. Every request made by Soapi is properly formed and directed so most any http error will be the result of a timeout or other network infrastructure. A retry buffer provides a level of fault tolerance that you can rely on.

• An almost identical javascript library, Soapi.JS, that will enable you to leverage your server cycles and bandwidth for only those tasks that require it and offload things like status updates to the client's browser.

##Download

Source code lives @ http://soapics.codeplex.com. Binary releases are forthcoming.

codeplex is acting up again.

get the source @ http://bitbucket.org/bitpusher/soapi.cs

The source is C# 3.5. and includes projects and solutions for the following IDEs

• Visual Studio 2008
• Visual Studio 2010
• ModoDevelop 2.4

##Documentation

Full documentation is available at http://soapi.info/help/cs/index.aspx

##Sample Code / Usage Examples Sample code and usage examples will be added as answers to this question.

• Soapi.CS Full API Coverage all API routes are covered
• Soapi.CS Full Parameter Parity If the API exposes it, Soapi giftwraps it for you.

The CS/SL/WP7/MONO libraries all compile the same code and with the exception of environmental considerations of Silverlight, the code samples are valid for all libraries.

You may also find guidance in the test suites.
