Anna

Anna is an event-driven HTTP server library built with ReactiveExtensions (Rx). Anna was inspired in Node.js and Nancy.

Anna exposes observable sequences of HTTP requests to which you can subscribe to handle the request.

using (var server = new HttpServer("http://*:1234/"))
{
    // simple basic usage, all subscriptions will run in a single event-loop
    server.GET("/hello/{Name}")
          .Subscribe(ctx => ctx.Respond("Hello, " + ctx.Request.UriArguments.Name + "!"));

    // use Rx LINQ operators
    server.POST("/hi/{Name}")
          .Where(ctx => ctx.Request.UriArguments.Name == "George")
          .Subscribe(ctx => ctx.Respond("Hi, George!"));

    server.POST("/hi/{Name}")
          .Where(ctx => ctx.Request.UriArguments.Name == "Pete")
          .Subscribe(ctx => ctx.Respond("Hi, Pete!"));
}
